The USGS Headwaters Province project in western Montana and
northern and central Idaho was designed to provide geoscience data
and interpretations to Federal Land Management Agencies and to
respond to specific concerns of USDA Forest Service Regions 1 and
4. The project has emphasized development of digital geoscience
data, GIS analyses, topical studies, and new geologic
interpretations. Studies were designed to more completely map
lithologic units and determine controls of deformation, magmatism,
and mineralizing processes. Topical studies of geologic basement
control on these processes include study of regional metallogenic
patterns and their relation to the composition and architecture of
underlying, unexposed basement; timing of igneous and hydrothermal
systems, to identify regionally important metallogenic magmatism;
and the geologic setting of Proterozoic strata, to better
understand how their sedimentary basins developed and to define the
origin of sediment-hosted mineral deposits. Interrelated products
of the project are at complementary scales.
