Eric D. Anderson, Ph.D.
Eric Anderson is a Research Geophysicist with the Geology, Geophysics, and Geochemistry Science Center.
Eric's research is focused on solving mineral resource problems through the theory and application of geophysical methods. He integrates geophysical data with geology and mineral deposit models to understand the three-dimensional geologic framework within which ore deposits occur. He works mostly in the western US on mineral deposits that form in convergent margin settings.

Airborne electromagnetic and magnetic survey data, Silverton, Colorado, 2019 Airborne electromagnetic and magnetic survey data, Silverton, Colorado, 2019
Airborne electromagnetic (AEM) and magnetic survey data were collected during April and May 2019 along 1,467 line-kilometers in the San Juan-Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field. Data were acquired by Geotech, Ltd. with the versatile time-domain electromagnetic (VTEM-ET) system together with a Geometrics optically pumped cesium vapor...
Gravity data in the Wet Mountains area, southcentral Colorado, 2021 to 2022 Gravity data in the Wet Mountains area, southcentral Colorado, 2021 to 2022
The U.S. Geological Survey (USGS) collected gravity data in the Wet Mountains, CO from September 2021 to July 2022 to compliment newly collected airborne magnetic data for surface and subsurface geologic mapping. A total of 261 measurements were collected across two Ediacaran-Ordovician alkaline complexes (Gem Park and McClure Mountain) and gabbroic outcrops suspected Ediacaran...
Magnetic susceptibility measurements in the Wet Mountains, Colorado, 2021 to 2022 Magnetic susceptibility measurements in the Wet Mountains, Colorado, 2021 to 2022
The U.S. Geological Survey (USGS) collected rock magnetic susceptibility measurements to understand the causative sources of airborne magnetic survey anomalies in the Wet Mountains, Colorado. A total of 808 measurements were collected over 50 locations from August 2021 to June 2022 on rocks ranging from Paleoproterozoic to Oligocene age. These measurements aid the interpretation of newly...
Magnetic susceptibility measurements on hydrothermally altered rocks in the Silverton caldera, southwest Colorado Magnetic susceptibility measurements on hydrothermally altered rocks in the Silverton caldera, southwest Colorado
The U.S. Geological Survey (USGS) collected magnetic susceptibility measurements on rock outcrops to help understand causative sources of magnetic survey anomalies in the Silverton caldera region, southwest Colorado. A total of 1,400 measurements of magnetic susceptibility from 87 locations have been conducted on Paleogene volcanic and plutonic rocks that have been hydrothermally altered...

Resistivity imaging over porphyry copper systems in the Red Mountain district, southwest Colorado, USA Resistivity imaging over porphyry copper systems in the Red Mountain district, southwest Colorado, USA
The Red Mountain district in southwestern Colorado produced base and precious metals hosted in breccia pipes and vein structures related to an extensive lithocap that overlies pervasive quartz-sericite-pyrite alteration. A helicopter-borne time-domain electromagnetic survey flown over the district yielded resistivity values that range from tens to thousand or more ohm-m, with lesser...

Executive Summary The U.S. Geological Survey carries out a wide variety of multidisciplinary science projects through the Bureau’s regions, mission areas, programs, and science centers. However, this structure can limit interactions among individual scientists, segregate data holdings, and make it difficult to apply holistic, interdisciplinary science. In addition, technological advances...

Ediacaran-Ordovician magmatism and REE mineralization in the Wet Mountains, Colorado, USA: Implications for failed continental rifting Ediacaran-Ordovician magmatism and REE mineralization in the Wet Mountains, Colorado, USA: Implications for failed continental rifting
Structures associated with Ediacaran-Ordovician alkaline magmatism and the timing of rare earth element (REE) mineralization in the Wet Mountains, CO, were analyzed using field, geophysical, and U-Th-Pb isotope methods to interpret their tectonic setting in the context of previously proposed rift models. The Wet Mountains are known for thorium and REE mineralization associated with...

Introduction More than 840 publications, 575 data releases, and 330 project web pages from the U.S. Geological Survey (USGS) pertain to the Colorado River Basin. Limited interconnections between Colorado River Basin publications, data, and web pages restrict the ability to synthesize and interpret scientific resources. Currently, these pieces are spread across multiple isolated locations...
