Geology and mineral resources of the Baltimore, Boston, Lake Champlain, and Providence 10 x 20 NTMS Quadrangles. National Uranium Resource Evaluation Program

This document contains 4 geologic and mineral resources reports for the Baltimore, Boston, Lake Champlain, and Providence 10 x 20 National Topographic Map Series (NTMS) Quadrangles in the northeastern United States. The purpose of these reports is to provide background geologic and mineral resources information to aid in the interpretation of National Uranium Resource Evaluation (NURE) geochemical reconnaissance data. All the reports are accompanied by geologic and mineral locality maps; the Baltimore report contains a map of the geologic provinces and political boundaries, as well as two geologic cross sections. The maps, Plates 1 through 10, are found in the pocket on the inside back cover of this volume in microform. All four papers have been abstracted and indexed for the Energy Data Base
