The historical Berkeley Pit in Butte, Montana was developed during open-pit mining of polymetallic veins that overlie a porphyry stockwork vein deposit at depth. The veins are hosted in the Butte granite, one of many granitic phases of the Boulder batholith. View is to the north-northeast.
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.

Gravity data in the Wet Mountains area, southcentral Colorado, 2023
The U.S. Geological Survey collected ground gravity data as part of a helicopter reconnaissance campaign of the Democrat Creek alkaline complex and Deer Peak quadrangle in the Wet Mountains, Colorado. A total of 60 measurements were collected using a LaCoste and Romberg gravity meter. High accuracy geographic coordinates and elevations were collected using a survey grade Leica GS16 differential GP

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 resistivity va
