Eastern Mineral and Environmental Resources Science Center

The U. S. Geological Survey Eastern Mineral and Environmental Resources Science Center (EMERSC), part of the USGS Mineral Resources Program and based at the USGS National Center in Reston, VA, conducts unbiased research on the occurrence, quality, quantity, and availability of mineral resources in order to help the Nation make informed decisions using earth-science information.GEOPHYSICAL METHODS IN EXPLORATION AND MINERAL ...Magnetic exploration may directly detect some iron ore deposits (magnetite or banded iron formation), and magnetic methods often are an useful for deducing subsurface lithology and structure that may indirectly aid identification of mineralized rock, patterns of effluent flow, and extent of permissive terranes and (or) favorable tractsExam 03: Ch. 12: Mineral and Rock Resources - .Study 35 Exam 03: Ch. 12: Mineral and Rock Resources flashcards from Melissa B. on StudyBlue.
