Geochemical Database for Intrusive Rocks of North-Central and Northeast Nevada

By Edward A. du Bray, Michael W. Ressel, and Calvin G. Barnes

Oil Shale DataPreview Data

North-central and northeast Nevada contains numerous large plutons and smaller stocks but also contains many small, shallowly emplaced intrusive bodies, including dikes, sills, and intrusive lava dome complexes. Decades of geologic investigations in the study area demonstrate that many ore deposits, representing diverse ore deposit types, are spatially, and probably temporally and genetically, associated with these igneous intrusions. However, despite the number and importance of igneous intrusions in the study area, no synthesis of geochemical data available for these rocks has been completed. This report presents a synthesis of geochemical data for these rocks. The product represents the first phases of an effort to evaluate the time-space-compositional evolution of Mesozoic and Cenozoic magmatism in the study area and identify genetic associations between magmatism and mineralizing processes in this region.
