The USGS is conducting geologic mapping and scientific research of complexly deformed crystalline igneous and metamorphic rocks in the Northeastern United States. Current mapping activities are focused on 1:24,000-scale mapping in New Hampshire, Vermont, Connecticut, and New York, plus regionwide 1:500,000-scale compilation of the bedrock geology of New England. The project produces high-quality, multi-purpose digital geologic maps and accompanying databases and reports to solve diverse problems in high-priority areas. The research is part of a Federal component of the National Cooperative Geologic Mapping Program called FEDMAP. FEDMAP geologic mapping advances nationwide geologic mapping and associated research as mandated by the National Geologic Mapping Act of 1992 (Public Law 102-285). The FEDMAP program produces world-class digital geologic maps and 3D framework models based on state-of-the art observation and scientific interpretation directed by high priority national issues.
The goal of this project is to produce high quality 1:24,000-scale to 1:500,000-scale bedrock geologic maps that improve our understanding of crystalline bedrock in the Northeast United States. New detailed mapping is focused in areas where limited detailed or modern mapping exists. Compilation mapping aims to synthesize the geology of the region, address stratigraphic problems, develop stratigraphic correlations, and reconcile small-scale, cross-border edge-match issues that exist between the state geologic maps.
The new maps contribute to framework studies to help characterize the distribution natural resources and address outstanding questions about the tectonic evolution of mountain belts and the behavior of groundwater and groundwater contaminants in fractured rock. The large-scale geologic maps include detailed fracture information that can be used to characterize the recharge potential of bedrock lithologies and identify potential pathways for groundwater and contaminant flow. Geologic mapping activities are supported by modern geochemistry, geochronology, paleontology, and petrology in scientifically appropriate areas.
