Geologic Framework of the Intermountain West
The Geologic Framework of the Intermountain West (IMW) Project is creating a seamless, integrated, geologic map database that spans the Intermountain West region. The database will serve enhanced geologic map data to support geoscience research, environmental and resource assessments, and the communication of geologic information for all U.S. Geological Survey stakeholders.
This innovative approach to serving geologic map data synthesizes new and existing geologic mapping into a spatially consistent geologic framework, preserves source metadata, and improves the queryability of map unit information. The stratigraphic framework that underpins the geologic mapping is constructed dynamically using a process-based, time-dependent, hierarchical classification of map units. This data set can be integrated with users’ data via GIS hosted feature layers or can be viewed using the Intermountain West Geologic Map Explorer .
Research groups within this project investigate the magmatic, tectonic, stratigraphic, and landscape evolution of the Intermountain West through targeted studies of geologic processes.
