Anjana K Shah

Biography

Anji Shah is a research geophysicist with the Crustal Geophysics and Geochemistry Science Center in Denver, CO, specializing in the use of gravity, magnetic and radiometric methods for geologic characterization and interpretation. She is currently working on several projects involving subsurface geologic characterization for earthquake hazard, mineral resource, and energy resource applications. She also has a background in marine geophysics.

For earthquake hazard studies, Dr. Shah uses gravity and magnetic data to distinguish contacts between subsurface rocks with different densities or magnetic properties. In some regions, these contacts may delineate buried faults and other structures that suggest seismic risk (see this article for application to the 2011 Mw5.8 Mineral, Virginia earthquake). Gravity and magnetic data can also be used to distinguish areas that may be more likely to exhibit seismicity in response to fluid injection (see this article for application to north-central Oklahoma).

Dr. Shah has also led several projects involving imaging and evaluation of rare-earth-element (REE) deposits. Concentrations of REE-bearing minerals in certain geological environments can be detected using radiometric and magnetic methods.  Heavy mineral sands are of particular interest because their extraction involves minimal impact; REE-bearing monazite and xenotime have been observed throughout the southeastern U.S. (visit related project page).  The Eastern Adirondacks were mined in the 1800’s and 1900’s for magnetite. The ores also contain REE-bearing apatite, and often REE’s are present in mining tailings. A combination of geophysical, geological and geochronological approaches is being used to study this area (visit related project page).
