Drilling down on fracking in Indiana – IU Bloomington Professor Michael Hamburger in HT interview
Fron the IU Newsroom, a courtesy posting of a Bloomington Herald-Times article: Geologists and environmental activists have been raising concerns for years about increased hydraulic fracturing – called "fracking" for short – and other unconventional oil production methods in the United States. Hydraulic fracturing is the drilling and injection of fluid into the ground to create cracks in rock formations and release natural gas, oil and other energy-producing resources.
"It turns out that many things that we do that affect the subsurface of the Earth are also capable of triggering earthquakes,” said Michael Hamburger, a professor of geological sciences at Indiana University. “This is one of the unexpected side effects of oil and gas exploration. There are places in Kansas or Texas that have never experienced an earthquake that have now experienced an earthquake and have no idea what to do about them." IU Newsroom article
Indiana University geochemists model underground movement of stored carbon dioxide
Fron the IU Newsroom: Computer modeling by geochemists at Indiana University and colleagues in China and Sweden takes scientists several steps closer to understanding what happens when greenhouse gases are injected deep underground in a process called carbon capture and storage. Chen Zhu, professor in the Department of Geological Sciences in the College of Arts and Sciences at IU Bloomington and lead author of an article in the International Journal of Greenhouse Gas Control entitled, "Benchmark modeling of the Sleipner CO2 plume: Calibration to seismic data for the uppermost layer and model sensitivity analysis" said the model should apply to similar underground storage systems elsewhere, including carbon capture and storage projects that could be built in the U.S. Midwest.

If you are interested in participating, contact Gary Pavlis by the end of the day on Friday, Feb. 27.
David Grossnickle is a contributing author on Science article
Recent IU alum David M. Grossnickle, now at University of Chicago, helped describe the oldest known tree-dwelling mammal, Agilodocodon scansorius, from the Jurassic of China, whose specializations indicate that it feed on plant sap and other foodstuffs. Agilodocodon was a docodont, a stem branch of the mammalian radiation whose ecological specializations are now known to include not only tree-dwellers but also beaver-like swimming species, small burrowing species, and a range of dietary specializations from herbivorous to insectivorous. Grossnickle helped demonstrate that the proportions of the animal's limbs are more consistent with a climbing lifestyle than with other modes of life. The paper was published in the journal Science on 13 February 2015.
About his contribution, David writes, "I helped analyze the finger bone dimensions of the fossil and found that they are most similar to modern tree-dwelling mammals, providing strong evidence for our conclusion that the species lived in trees. This is especially significant because it means close relatives of mammals were diversifying ecologically in the Middle Jurassic, which is prior to similar diversifications by later mammal groups. The research benefitted heavily from quantitative methods and anatomical knowledge that I learned while studying under David Polly and Jackson Njau at Indiana University."

G420: Regional Tectonic field trip, May 10-23, 2015
A regional tectonic field course across the Appalachians from central Pennsylvania to Boston crossing many suspect terranes is being offered. Emphasis will be placed on interpreting the rock record.
This will include:
- making mineralogical, petrologic, and structural observations, and
- inductively synthesizing these observations into an understanding of the geological history of an outcrop or set of outcrops.
- integrating the geology learned from this collection of outcrops to an increased understanding of the Paleozoic evolution of the Appalachian orogen.
Skills expected to be sharpened include:
- hand lens petrography
- igneous, sedimentary, and metamorphic petrology
- recognition of multiple cleavages and fabrics, and use of the Brunton compass to measure their attitudes,
- structural mapping by pace and compass,
- and manipulation of stereonets
The course will be offered for 3 credits in the second 8 weeks of this semester, and will involve weekly meetings in seminar format to prepare for the field trip. The trip itself will actually leave Bloomington Sunday, May 10 (or Saturday, May 9 if possible) and return by May 21 or at the latest May 23rd.
Registration for 3 credits in Summer Intensive Session I can be considered but participation in seminars is required.
Prerequisites: Required - Competence in G222, Petrology. Recommended, G323. Structural Geology.
See Bob Wintsch (Gy 325) for details and authorization to register.

February 4, 2015: Department mourns the passing of Professor Haydn Murray
Prof. Haydn H. Murray passed away peacefully on February 4, 2015 in Bloomington, IN. Many of you are familiar with Haydn’s varied scientific contributions to applied clay science, and he was one of the few members of our science elected to the National Academy of Engineering in 2003. In addition, he made tremendous contributions to many aspects of Indiana University and was awarded an honorary doctorate in 2004. Prof. Murray mentored an incredible group of graduate students including 68 M.S. and Ph.D. students, and he served on an additional 60 graduate committees. He was also instrumental in establishing the Grassmann Fellowship for clay mineralogy graduate students and the Haydn Murray Chair of Applied Clay Mineralogy in the Department of Geological Sciences at Indiana University. His presence will be missed in the Indiana University community and in the greater international mineralogical community.
A memorial service will be held for Professor Murray at 2:00 pm on Saturday, February 21, 2015 in the Tudor Room at the Indiana Memorial Union. If you were close to Haydn or the family, Juanita, Haydn’s wife of more than 70 years, would be happy to hear from you. Her address is: 901 S. Fieldcrest Ct., Bloomington, IN 47401
A bill has been introduced in the Indiana Legislature to designate a state fossil for Indiana: the elegant sea lily, Elegantocrinus hemisphaericus.
Elegantocrinus hemisphaericus, the Elegant sea lily, is a crinoid, a group of animals that are related to starfish and sea urchins. Elegantocrinus was first discovered at Crawfordsville, Indiana in 1865.
This crinoid was first described from the famous Mississippian-aged Borden Group crinoid beds at Crawfordsville, Indiana. Originally classified in the genus Platycrinites, the species was moved to the new genus Elegantocrinus by department alum Bill Ausich (now of Ohio State University) and Tom Kammer. The platycrinid group is distinctive in having oval shaped columnals, which are the round bits that made up the stem of the crinoid, common around Monroe Lake and elsewhere. E. hemisphaericus itself is also found at Monroe Lake. Here’s a PDF file with more information about the fossil.
The 500 Earth Sciences Club and the Indiana Society of Paleontology are the groups that have worked to push the bill forward. Both sites have a photo of a beautiful calyx of E. hemisphaericus on their homepage. The bill is SB114, which is introduced by the bipartisan pair of Mark Stoops (District 40 - Bloomington’s senator) and Philip Boots (District 23 - Crawfordville’s senator) can be viewed here. SB114 has initially been assigned to the senate rules committee.
Evolution of the snake body form reveals homoplasy in amniote Hox gene function
From the Bloomington Newsroom: Skeleton study sheds new light on how snakes evolved
Research by paleontologists at Indiana University and the University of Nebraska sheds new light on how snakes evolved their elongated, legless bodies.
Hox genes, which establish the boundaries of the neck, trunk, lumbar, sacral and tail regions in birds, lizards, crocodiles and mammals, were previously thought to have been disrupted in snakes, resulting in a loss of regions in their seemingly simplified body form as they evolved from four-legged lizard ancestors.
P. David Polly of Indiana University and Jason Head of the University of Nebraska-Lincoln examined regional differences in the shapes of individual vertebral bones in snakes, lizards, alligators and mice. Snakes are different from these other amniote groups in that they lack forelimbs, shoulder girdles and sternal skeletons. Snake vertebrae were assumed to have become less regionalized when the limbs were lost. IU Newsroom article and the Nature article
