GSA 2016 - Denver, Co

Kevin Gardner :

Hello, UALR!!!

 I have yet to post to until now due to the adventurous journey from Little Rock to Kansas, Kansas to Denver, in Denver, and then the flight home. But I will admit, waiting to blog until now was a huge mistake! I have so much to talk about!

THE JOURNEY:

Let us begin with the drive. Simply, it was great! I have never been north of Belle Vista, Ar on I-49 until this trip. Observing the scenery was a wonderful experience! We stopped at the Joplin History and Mineral Museum that had rock and mineral specimens from the mines in the area, and lots of historical artifacts and replicas. Though I enjoy unique rocks and minerals, I will say that at this stop I enjoyed the history more. The stories and pictures from the old, original town and mines were interesting to see and put the work that went into establishing the area into major perspective.

We spent the night in Salina, Kansas and continued our journey the next day. The windmills were EVERYWHERE!!! I'm talking ~400 feet tall! The blades that are manufactured near the LR airport are actually being put to use in rural Kansas... Pretty cool!

We made a stop at the Fort Hays University Museum of Natural History where we able to see an extensive collection of live rattlesnake species (photos not allowed for snake safety/stress on the snakes), which was fascinating. They also had lots of fossil displays, and even showed how they removed the fossils from rock to display them within the museum.

You may have heard of the newer fish species that can breath outside of water and has arms that allow them to walk across land... Well, here you go! The little fella actually does breath air outside of water and has real, little arms!

Even though I enjoyed this stop very much, I will say that I had a constant feeling of insecurity. I'm not quite sure what the problem was, but I felt uneasy, followed, and VERY SMALL! I even heard strange noises behind me at times (image below)... Perhaps we will never know the real reason behind these feelings?

We eventually arrived in Colorado and, after a short time, the Rocky Mountains were visible. We entered Denver and were all very excited to be there. I never realized that Denver sits before the front range of the Rocky Mountains and is actually a flat city. The mountainous landscape in the background sure was good for pictures though!

The GSA meeting began with an "Ice-Breaker" social gathering for all attendees. It was nice, but very crowded. We rested off our road trip tiredness and prepared for the busy schedule of talks and presentations ahead.

TALKS:

I attended lots of great sessions, posters, discussions, and talks of current work being done in the earth science field. One of the talks was from Dr. David London, University of Oklahoma. Dr. London is working on pegmatite (a large, course grained, igneous rock) research. I had the privilege of visiting OU and Dr. London about two weeks ago for my own research presentation being presented in Denver at this meeting. Dr. London in his talk was attempting to identify why the zoning of minerals normally always occurs in pegmatites, and what causes the zoning of the minerals in very uniformed and predictable ways. Long story short, through his experiments, Dr. London was able to correlate the host rock of the pegmatite intrusion to the zoning across the pegmatite. If the host rock where the intrusive melt makes contact is calcium (Ca) rich, then the melt begins to crystallize Ca-rich minerals first, against the Ca-rich host material. The melt will deplete its Ca content as it works towards the center, making component substitutions as it loses components in the melt. This, overall, will give the appearance of zoned minerals in the pegmatite once it has cooled and viewed as a whole. Very interesting stuff, especially since my research presentation is on pegmatites. I also attended a mineralogy/petrology teaching talk. It was amazing!!! I can not wait to talk to Dr. DeAngelis about the details of this teaching research and the new tools for teaching the material that I observed.

I gave my presentation on the last night of the conference and enjoyed my experience very much. This was the first time that I have presented any material outside of the UALR campus and the EIT research expo. I was a bit nervous initially, but quickly got over it as the evening progressed.

I was able to meet several interesting people from across the country and world that all have an interest in pegmatites and the minerals that form them. One notable attendee that I spoke with was from the Museum of Natural History in Washington, D.C. and is friends with one of my references/sources that I have used in my research presentation(s).

It was a great trip and atmosphere to experience. I hope that I am privileged with another opportunity to attend a GSA meeting and present further research in the future.

*** More to come shortly: an amazing Feed Your Brain discussion that was definitely a highlight of the trip.

Fulfillment of Dreams at GSA

Wow! What an exceptional great time I have had attending the 2016 Geological Society of America conference in Denver, Colorado the "Mile High City". This was not my first GSA conference, nor will it be my last.

What can I talk about that won't be a bazillion words long?

I attended so many talks in these past few days. Much of my time has been spent literately "camping" out in one room all morning. Much of this time has been spent with me mouth open in aww with all the exciting topics coming out of the Hydrogeology division and the Karst division. I went to other talks as well regarding Geoinformatics, Energy Conservation, and even Geology and Religion.

This year was the first year that I knew what people were talking about in the talks. I can safely say that after all of my core classes in the UALR Geology program that it has made me gained the knowledge that is needed to think like a Geo-scientist. I feel like I have taken something away from this conference and that is that I cannot wait to spend everyday with awesome professionals and researchers doing the things I enjoy. Learning, Collaborating, Motivating.

While at GSA, I met with so many bright and intelligent people. I was selected to participate in the GSA Hydrogeology Division lunch and award ceremony where I had the opportunity again to use my formal dinner etiquette skills. I also had a table full of top researchers from schools like Nebraska and UC Davis.

  Also I got to meet with several different graduate schools.

My most exciting moment of this trip was when I had the opportunity to me with Jason Polk from Western Kentucky University, a professor in the Karst division. I talked to him and his students about the exciting things going on at WKU. It's a top school on my list of schools I will be applying to for the Fall '17.

Another person I got to speak with was John Mylroie, professor emeritus from Mississippi State University. Mylroie is one of the leading researchers for Karst environments on San Salvador, Bahamas. I have read several papers that he has published and when we saw each other both of our faces lit up. He remembered me from attending a talk that he did at UALR. Mylroie is my idol in the Geoscience world.

Overall, this has been a great trip!

I want to think the University and the Department of Earth Science for allowing me to attend this conference.

Quandaries and Questions: A GSA Experience

At the end of each conference day, it's all come down to questions. 

Today is Wednesday, and we have only a few more hours left at GSA 2016. I've gone to over thirty different talks on everything from preservation of rivers in the rock record to the role sexual versus asexual reproduction plays in survival likelihood during major extinction events. During these presentations I've been struck by a number of different emotions: excitement, boredom (I do not give a single damn about microbial mats, no matter how hard I try), confusion, and (on Monday after seemingly endless fancy statistical analyses that I couldn't make heads or tails of) utter despair that I'll ever be smart enough to make any meaningful contributions to the geologic community. 

However, my main take-away from these technical sessions hasn't been discouragement but overwhelming curiosity. Almost every talk has inspired new questions. After several discussions about megafaunal extinctions at the end-Pleistocene, I want to learn more about the influence of body size on survival chances during extinction events. A geoscience education talk about using phylogenetic trees in a non-major historical geology class made me wonder what other creative tools could be used to engage non-science majors in geology classes. In a session about the conflict between the conservative religious and the scientific communities, I started thinking about how some of the approaches presented by the speakers could be incorporated into introductory geology courses. 

Even though I felt as lost as an accountant in a mineralogy class in a good portion of the talks, what I did understand greatly enhanced my knowledge base and, even more importantly in my opinion, started me thinking in terms of potential research directions that I myself would like to pursue rather than simply learning from the research of others. And this, I believe, is the first step towards the next phase of my career.

Best GSA Ever

Good Morning, 

Today is the last day of GSA, and I feel like I have taken full advantage of the conference. Monday and Tuesday I volunteered, with yesterday  being the most interactive day.  I hung around the speaker ready room helping presenters upload their presentations.  This was really fun, and a great opportunity to meet as many professors from all over.  It was also great to meet Phil Wernette from Texas A and M.  We talked a lot about research, and had an immediate bond, and connection due to our fondness of geology.  I will go to as many talks today as possible, and take off some time around noon to catch my flight at 3:45.  For now this is me signing off.

Harper's GSA Poster

Poster Time! Man I need to lose some weight!

Sunday was time to present and I was a little apprehensive, but after a few moments and several visits from my compadre's from UALR, relaxation finally set in. Many people came by who were interested in the carbonatites. Dr. Peter Modreski shared with me the similarities between the carbonites at Magnet Cove with those of the Iron Hill Carbonatite Complex in Colorado. Another related them to those in the Rift Valley of Africa.

One of the more interesting visits was with Dr. Nelson Eby from the University of Massachusetts Lowell. He has done EPMA analysis on the mica of Magnet Cove and steered me to his website. There he has a wealth of information on the mica. This should be of great help with the future work I want to do regarding the Magnet Cove Mica.

So, the contacts I have made here at GSA have made the trip worthwhile. Looking forward to our remaining time here and the people I will meet and information I will attain.

Feed Your Brain

Monday afternoon, I attended a "Feed Your Brain" lunch time discussion. The discussion was led by Jen Russel-Houston. Jen works at Osum Oil Sands Corp. located in Alberta, Canada.


What are oil sands you may ask? Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen.


Canada is right behind Saudi Arabia for number or oil reservoirs. Most of this oil that comes from Canada will filter to the United States for refining. Canada ranks in at number 3 and the United States ranks in at number 6 for producing oil. Together however, we are ranked number 1.


In Jen's talk, she stated that retrieving oil from oil sands is hard. Her company is developing new ways in better locating and extracting it. One method that the company uses is called Steam Assisted Gravity Drilling or (SAGD)


Using such method requires a lot of wells, more water, and a larger footprint


Jen's goals is to eventually lower cost, safer operations, lower water use, and reduce the footprint


In the future she [Jen] wishes to optimize and become more efficient with steam, she wants to put more wells on one pad, and wants to have better well placement and reservoir quality

Monday Blues

Attended a couple of excellent sessions today. The first was on Evolution of the Rocky Mountains. The discussion of the Larimide orogeny was informative. The second session I enjoyed was on petrology and orogenic systems. Use of garnet-spinel-corundum ternary diagrams brought back fond memories of Igneous Metamorphic Petrology.

Chris Butterworth’s blog:

On our way to GSA we stopped at Joplin History and Mineral Museum in Missouri, where there are displays of mining equipment and samples of the minerals mined there.  These are mainly galena and calcite.  Upstairs are models of the local mines, showing shafts and seams.  There are also displays of items from a bygone age, as are found in most local museums.  There were vendors of gems, minerals and fossils, and I bought a couple of 40 million year old (according to the vendor) shark teeth for my son.  I avoided the Moroccan trilobites as they have a reputation for being fake.

In Kansas we stopped at Fort Hays State University’s Sternberg Museum of Natural History.  This is a large building under a dome, with a simulated journey through time in the middle, with large mockups of dinosaurs, one of which growls so loudly that it can be heard all over the museum.  For a local museum this one has an impressive set of collections, which are Paleontology, Paleobotany, Geology, Botany, and Zoology.  Most of these were relevant to us.  I photographed all the snakes in the exhibit at the lower level under the central dome.  These were of interest to me, having studied zoology in the spring.  Then I walked up the slope representing different geological periods, with models of various reptiles.  For the 80 million year point was also marked by a boundary between Kansas and Colorado, mainly because of the location of local sites where many fossils were found.  The actual fossils were displayed in glass cases, including their famous “fish within a fish.”  I took a selfie in front of a mammoth skeleton, and then tried to take in the dozens of minerals on display.  I would have liked to stay for longer but we were on a schedule.

I spent my first day at the annual meeting of the GSA in Denver listening to talks about Mars.  The morning session was a collection of talks about sedimentary geology in Gale Crater, based on satellite photos and data collected by Curiosity Rover.  The afternoon session was about igneous geology from previous Mars missions and from meteorites from Mali.  I have chosen to write about a morning session talk by Kathryn M. Stack called “Facies Analysis and Stratigraphic Context of the Pahrump Hills Outcrop, Type Locality of the Basal Murray Formation, Gale Crater, Mars.”

Curiosity Rover has spent the last four years climbing Mount Sharp in Gale Crater.  This sounds dramatic but the “mountain” is actually not steep and the rover can easily drive up its gradient.

The rover landed at a place called Aeolis Palus at the foot of Mount Sharp, which lies within Gale Crater.  The area is named for the type of deposits found there: wind-blown sediments, with coarse cross-bedding.  Satellite photos show that this is in the lowest unit of Mount Sharp, the Murray Formation.  Curiosity spent two years there and then crossed a facies boundary into the Palump Hills outcrop.  Here it photographed features such as conglomerate rocks, resistant ridges, platy-bedded lenses, and resistant outcrops.  In the distance could be seen the mesas of the Bradbury Group and the Stimson Sandstones.

The field strategy used was to walk this outcrop using Curiosity’s ChemCam, which can do laser spectroscopy, and its MastCam.  Several stops were selected because they looked interesting, and, for the sake of objectivity, other points were chosen between these spots precisely because they were not interesting.  The rover’s core sampling drill and its “hand-lens” tool were used to examine the rocks at some of the points.  The sandstones and gravels found here were of fluvial origin but the mudstones had grains so fine that they could not be resolved under the lens.  They must have been deposited under deep water, and some of their laminations were fine and regular, others less well-expressed.

Kathryn described some bedding features called “scour and scrape” structures, along with the “climbing ripples” found at a feature called Newspaper Rock.  Rover was able to examine sandstone from a higher elevation without going there, because a large boulder had rolled down the hill.  At this point Kathryn’s team was able to reconstruct the depositional environment as being plunging plumes which created mudstone in lacustrine varves, without aeolian ripples.  The scour and drape bedding was, apparently, indicative of hyperpycnal flows.  The overall environment was a deep body of varying depth, with plunging river plumes flowing turbidly down the slopes.

One of Kathryn’s team members is Dr Linda Kah, with whom I hope to do some research for my Master’s in Applied Science.  This talk gave a very interesting background into the work being done by Curiosity Rover in Gale Crater.

On Monday I spent the morning as an alternate student volunteer, and in the afternoon attended the sessions on Aeolian transport mechanisms.  Most of these talks were about Mars, and there was much overlap with the previous day’s material.

Good Evening Everybody!

Today I had a great time at GSA.  For the first part of the day I went to a bunch of Geomorphology talks, and learned a lot of information about what type of research there is in the geomorph field.  After lunch where I ate at fresh market on 16th street mall, I had a volunteer spot.  This involved being trained to help as a technical session helper.  I aided at 1:30-5:45, on the talks about national parks, research, mapping, and more.  One particular talk I found interesting was on phosphate in Loch Vale lake, in Rocky Mountain National Park.  According to the speaker 0.1 % of apatite (a mineral composed of Ca5(PO4)3(Cl,F,OH))) was being dissolved off the rocks nearby, and deposited into the lake.  He was looking at how much phosphate (PO4) was being left behind in the lake after snow melt.  Quite the beautiful lake if you haven't ever been up to Loch Vale Lake, crystal clear, with scenic views of Longs Peak, and Timberlake Falls.  Personally this is one of the lakes I've been to many times.  In fact I believe it was one of the hikes I did in Rocky Mountain National Park at the age of 6.  At any rate, I hope you enjoyed the read.

Signing off,

GSA 2016

Hi all,

As of today (9/26/2016) I have been to talks on topics ranging from 3D models of field areas created using photogrammetry to paleoenvironments associated with the origins of the genus homo. I have learned much from the talks so far, but the most productive time I have spent has been the time I've spent at the posters. There were "digital poster sessions", at which the presenters demonstrated a variety of digital models and virtual field trips created from an even larger variety of relatively recently-developed software. At these poster sessions I was able to pick the brains of those applying this software and network without the time constraints of the talks. 

That's all for now!

GSA 2016-Monday September 26

Hey Readers,
This is Matt Carey and I will be writing about the past couple days at the GSA 2016 conference.  I had the opportunity yesterday to sit in on a talk given by Dr. DeAngelis, on a class he taught a couple of semesters ago about planetary geology.  Dr. DeAngelis is a fantastic speaker and his enthusiasm for teaching is very clear.  After that Jason and I checked out the Celebration of Lakes technical session.  The most interesting talk I heard was on Garibaldi Lake of British Columbia, Canada.  This lake was formed volcanically by a dacite flow damming snowmelt.   The research was mostly focused on bathymetry calculations and orthoimagery created from drone photography.  The use of drones is a popular thing I've noticed and has got me interested in learning how to use one for my own research.  Later that day, after some Indian buffet and a nap, I checked out the poster presentations.  I met a man from the University of Santa Barbara who has been studying giant stromatolites in the Green River Formation of northwest Colorado.  Let me tell you, these suckers are huge.  A standard size was 5 meters tall by 7 meters wide.  At the bottom of most of these stromatolites were logs.  The logs served as a base for the stromatolites to grow off of.  Having only been exposed to stromatolites that formed within marine type environments, it was so cool to have something new to compare with my past knowledge.  Earlier this morning I sat in on talk titled Unearthing the History of Women in Geosciences.  Geological history is something I have not been exposed to much and after the talk I want more.  I heard the life story of a woman named Tilly Edinger.  She was the founder of a paleontological subfield called paleoneurology.  If you would like to know more about this come find me and I will blabber wildly about it.  Another great thing about today was I have got to spend time with my greatest friends ever and UALR graduate Ashley Horton.  Conferences are great for reconnecting with friends who I do not get to see often.  Thanks for the read.

Tri-State Mineral Museum

The Tri-State Mineral Museum in Joplin, MO is impressive! Be prepared for LOADS of Galena (hint: it's the state mineral - thanks Kuper). The best part is, the meseum is free! My favorite piece so far, the giant chunk of Galena with Sphalerite, Marcasite, and Dolomite.



See you soon,
Jason
