V. J. Grauch
V. J. S. ("Tien") Grauch has been employed by the U.S. Geological Survey in Denver, Colorado since 1977, where she is currently a Scientist Emeritus (senior research geophysicist) with the Geology, Geophysics, and Geochemistry Science Center.
Her research interests include application of high-resolution aeromagnetic data to map intrasedimentary faults, integration of geologic and geophysical data to develop 3D geologic and hydrogeologic frameworks, the relation between magnetic sources and geology, interpretation of aeromagnetic data over rugged magnetic terrain, and development of new interpretation methods.

Aeromagnetic expression of faults that offset basin fill, Albuquerque basin, New Mexico Aeromagnetic expression of faults that offset basin fill, Albuquerque basin, New Mexico
High-resolution aeromagnetic data acquired over the Albuquerque basin show widespread expression of faults that offset basin fill and demonstrate that the aeromagnetic method can be an important hydrogeologic and surficial mapping tool in sediment-filled basins. Aeromagnetic expression of faults is recognized by the common correspondence of linear anomalies to surficial evidence of...

High-resolution aeromagnetic data, a new tool for mapping intrabasinal faults: Example from the Albuquerque basin, New Mexico High-resolution aeromagnetic data, a new tool for mapping intrabasinal faults: Example from the Albuquerque basin, New Mexico
High-resolution aeromagnetic surveys flown over the Albuquerque basin, New Mexico, demonstrate that aeromagnetic methods can successfully map concealed and poorly exposed faults in sediment-filled basins. This is the first known use of aeromagnetic data as an aid to surficial mapping and hydrogeologic studies in a basin. Aeromagnetic maps show detailed fault patterns within the basin...

Principal facts for gravity data collected in the southern Albuquerque Basin area and a regional compilation, central New Mexico Principal facts for gravity data collected in the southern Albuquerque Basin area and a regional compilation, central New Mexico
Principal facts for 156 new gravity stations in the southern Albuquerque basin are presented. These data fill a gap in existing data coverage. The compilation of the new data and two existing data sets into a regional data set of 5562 stations that cover the Albuquerque basin and vicinity is also described. Bouguer anomaly and isostatic residual gravity data for this regional compilation...

Digital airborne time domain electromagnetic data from surveys over Cochiti Pueblo, Rio Puerco, and Rio Rancho, New Mexico Digital airborne time domain electromagnetic data from surveys over Cochiti Pueblo, Rio Puerco, and Rio Rancho, New Mexico
The Albuquerque-Santa Fe region is rapidly growing. The Santa Fe Group aquifer in the Middle Rio Grande Basin (MRGB) is the main source of municipal water for the greater Albuquerque metropolitan area and is more limited than previously thought (Thorn et al., 1993). The MRGB, as defined hydrologically and used here, is the area within the Rio Grande Valley extending from Cochiti Dam...

Geophysical framework of the southwestern Nevada volcanic field and hydrogeologic implications Geophysical framework of the southwestern Nevada volcanic field and hydrogeologic implications
Gravity and magnetic data, when integrated with other geophysical, geological, and rock-property data, provide a regional framework to view the subsurface geology in the southwestern Nevada volcanic field. The region has been loosely divided into six domains based on structural style and overall geophysical character. For each domain, the subsurface tectonic and magmatic features that...
