Structural Geology Lab

Computing Lab for Structural Geology and Tectonics Research

Lab Supervisor:

Dr. David R. Lageson, Professor of Geology

Lab Mission:

The purpose of the structural geology and tectonics research laboratory is to provide high-end computing capabilities and field equipment that support surface and subsurface structural analysis and synthesis. The lab offers software capabilities that are currently used in industry, thus providing training and experience for graduate students in computing applications they will likely encounter after graduate school. In addition, the lab provides office space for graduate students under the direction of Dr. Lageson.  Primary users include Dr. Dave Lageson, Dr. Colin Shaw (Research Professor), and an outstanding group of masters and doctoral graduate students in structural geology.

Lab Support:

The structural geology and tectonics research laboratory has been generously supported for several years by Scott Larson (former MSU student) and his employer, El Paso Exploration and Production Company.  Thank you Scott and El Paso E&P!  Other organizations have generously helped to fund the research of graduate students in structural geology over the years, including the MSU Energy Research Institute for carbon sequestration, USGS EDMAP program, GSA, AAPG, RMAG (Rocky Mountain Association of Geologists), TRGS (Tobacco Root Geological Society), Marathon Oil, MAGIP (Montana Association of Geographic Information Professionals), the MSU Department of Earth Sciences with various in-house awards, and others.  Thank you!
