Mike Hudec was interviewed by filmmaker Wendy Taylor of Arizona State University for a Virtual Field Trip to Upheaval Dome, Utah. The origin of Upheaval Dome is contentious, with competing hypotheses of meteor impact and pinched-off salt dome. Mike was presenting arguments in favor of the salt-dome hypothesis. The virtual field trip can be found online here, or Mike’s 19 podcasts can be found on YouTube here. If we all work together we can push Mike’s YouTube hits up into the double digits!

BEG

May 1—AGL is pleased to announce three job openings:

Position #1: Early-career salt tectonics. We are looking for expertise in structural geology or stratigraphy with interests in structure. The research scientists will study the evolution of salt structures using 3D seismic data and section restoration to determine principles governing their behavior. Experience with workstation seismic interpretation is required, and experience in salt basins or section restoration would be beneficial. We hope to fill this position either with a postdoc or with somebody having 0–10 years of work experience. We will begin reviewing applications on June 1. More information and instructions for application are available on-line at https://utdirect.utexas.edu/apps/hr/jobs/nlogon/140509030708.

Position #2: Mid-career salt tectonics. We are looking for expertise in structural geology or stratigraphy with interests in structure. The research scientists will study the evolution of salt structures using 3D seismic data and section restoration to determine principles governing their behavior. Experience with workstation seismic interpretation is required, and experience in salt basins or section restoration would be beneficial. Qualified individuals should have 10–25 years of experience. We will begin reviewing applications on June 1. More information and instructions for application are available on-line at https://utdirect.utexas.edu/apps/hr/jobs/nlogon/140509010708.

Position #3: Early-career geomechanics. We are looking for expertise in geomechanical numerical modeling and soil/rock mechanics, and experience modeling fluid flow in conjunction with large deformations. The candidate will be part of an integrated team of geologists and engineers and use state-of-the-art numerical modeling to couple complex soil behavior with geological-scale deformation in settings ranging from salt basins to thrust belts. We hope to fill this position either with a postdoc or with somebody having 0–10 years of work experience. We will begin reviewing applications on June 1. More information and instructions for application are available on-line at https://utdirect.utexas.edu/apps/hr/jobs/nlogon/140509020708.

On May 23 Mike Hudec met with filmmaker Wendy Taylor from the Arizona State University School of Earth and Space Exploration to film a series of podcasts on the salt-tectonics model for the origin of Upheaval Dome, Utah. ASU is building a series of web-based virtual field trips with funding through the NASA Astrobiology Institute. The virtual field trip will present both the meteor-impact and salt-dome-pinchoff models for the evolution of the enigmatic structure.


Luo

May 30 – AGL bids a regretful farewell to Gang Luo, who leaves us to accept a faculty position at the University of Chinese National Academy of Sciences in Beijing. Gang joined AGL in 2009, and (with Maria Nikolinakou) was instrumental in re-inaugurating AGL’s finite-element-modeling program in collaboration with Peter Flemings’ UTGeoFluids consortium. Gang’s expertise and sense of humor will be sorely missed, but we wish him all the best in his new assignment.
