Field trip guide to selected studies of the Southwest Mineral and Environmental Investigations Project in southeastern Arizona Field trip guide to selected studies of the Southwest Mineral and Environmental Investigations Project in southeastern Arizona
The Southwest Mineral and Environmental Investigations Project is designed to address issues raised by rapid urban development in the basins of the southwestern U.S. These issues require objective geoscientific data that can be used by land managers and stakeholders to develop informed land and water use strategies. The project integrates new and existing geologic, geophysical, and...

Geology and mineral resource assessment of the Venezuelan Guayana Shield at 1:500,000 scale; a digital representation of maps published by the U.S. Geological Survey Geology and mineral resource assessment of the Venezuelan Guayana Shield at 1:500,000 scale; a digital representation of maps published by the U.S. Geological Survey
This CD-ROM contains vector-based digital maps of the geology and resource assessment of the Venezuela Guayana Shield originally published as paper maps in 1993 in U. S. Geological Survey Bulletin 2062, at a scale of 1:1 million and revised in 1993-95 as separate maps at a scale of 1:500,000. Although the maps on this disc can be displayed at different scales, they are not intended to be...

Nonfuel mineral resources in the United States-Mexico border region: A progress report on information available from the Center for Inter-American Mineral Resource Investigations (CIMRI) Nonfuel mineral resources in the United States-Mexico border region: A progress report on information available from the Center for Inter-American Mineral Resource Investigations (CIMRI)
The exploitation of minerals has played a significant role in population growth and development of the U.S.Mexico border region. Recent proposed changes in regulations related to mining in the United States and changes in mining and investment regulations in Mexico have led to increased mineral exploration and development in Mexico, especially in the border region. As a preliminary step...
