Description:
Abstract:
This geodatabase contains 2 feature classes: formations (polygon features) and contacts (line features). Both were digitized from the 1:250,000-scale Bedrock Geologic Map of New Hampshire (Lyons and others, 1997). The Bedrock Geologic Map displays the type, location, and geologic age of the rocks underlying the state. The map is a compilation of decades of work by geologists who mapped individual portions of the state at various times. Polygon features found in these data display the location and extent of each mapped bedrock body in the state. Line features found in these data include contacts between individual rock units, and geologic faults.
Purpose:
The dataset is intended to provide general locations and characterizations of bedrock units (formations feature class) and bedrock contacts and faults (contacts feature class) to enable spatial analyses and comparisons of bedrock types to be performed by geologists, engineers, planners, and the public.
