Metallogeny of the Great Basin: Crustal Evolution, Fluid Flow, and Ore Deposits

Project Objectives

Key objectives of this project were

1. synthesis of the enormous amount of information generated over past decades in the Great Basin by the USGS, States, academia, mining and petroleum industry into an atlas of digital maps, cross sections, and relational databases,
2. these maps, sections and databases augmented and combined with new information from critical topical or geographic areas to address fundamental problems of ore genesis for a variety of ore deposit types,
3. a digital 4-D geologic model constructed in northern Nevada that encompasses the major mineral belts,
4. detailed 4-D models constructed for large mining districts such as the Carlin trend,
5. the 4-D models used to reconstruct the geology for important periods of ore formation on regional and district scales, and
6. the resulting 3-D reconstructions the foundation for numerical models of fluid flow, metal transport, and ore deposition.

Relevance & Impact

The geologic maps, sections, data bases, 4-D models and reconstructions produced by this project will be valuable products in their own right and will increase understanding of the geology of the Great Basin and the relation of ore deposits to its tectonic history. Documentation of the spatial and temporal relationships between ore deposits of different types and ages together with the fluid flow and chemical modeling results will result in an improved understanding of the fundamental controls on metallogeny in this world class gold province and the roles of crustal structures and inheritance in mineral belts. The identification of these controls and the methods of study developed during the course of this project are exportable to other regions of interest and should be of value to future metallogenic and assessment studies at home and abroad. Further, resulting data and interpretations, in particular an information bank on areas in the Great Basin likely to receive focused attention from the mining industry in the future, will provide scientific syntheses highly relevant to decision makers in other Federal, State, and Local agencies.
