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).

Extensive core drilling has delineated a large, deep seated, structurally intact deposit here. Distribution of elements and minerals determined for this study provide a zoning model applicable to similar deposits and useful for resource exploration.

Audiomagnetotelluric (AMT) sounding data collected in 2008 in this area in support of assessments of concealed mineral resources.
