Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits.

Spatial databases for map units, strike and dip, geologic contacts, faults, dikes, in addition to a topographic base map are provided in an Esri file geodatabase. The geologic mapsheet is also provided as a PDF.

Surficial geochemical methods used to identify subsurface mineral deposits covered by alluvium. Can a geophysical anomaly, interpreted as a buried granite pluton, be discerned from the geochemical characteristics of overlying Quaternary sediments?

Geologic map GIS which represents the original content of the published geologic map and which can be queried in many ways to produce a variety of geologic maps and derivative products.

Measurements of in-situ magnetic properties of several map units to determined whether or not mapped lithologies were responsible for aeromagnetic anomalies observed in a previous high-resolution survey (data of Sweeney, 2000).
