In the policy literature and the popular press, the issues of water and conflict are
being raised together with increasing frequency. Geographic, international relations, and
environmental security theories speculate on the linkages between geographic features,
natural resources, spatial relationships, and war or acute conflict. Little quantitative or
global-scale research exists,...
The Tobin Range of central Nevada lies in the Basin and Range extensional
province near the transition between more extended terrane (>50%) to the south and
east, and generally less extended terrane to the north and west. Geologic mapping,
40Ar/39Ar dating and whole-rock geochemical analysis were employed to establish the...
The study of the subsurface flow and distribution of water is critical to the
evaluation of the unsaturated zone for a potential geologic high-level radioactive
waste repository. This site is located at Yucca Mountain, Nevada in the northern
Mojave Desert. and was chosen on the basis of its low precipitation,...
The Garnet Range-Bearmouth area of western Montana was the
depositional site for basinal, platform slope, shelf, and
peritidal Mississippian carbonate rocks. The following
stratigraphic units, listed in ascending order, are recognized:
the Paine Limestone, Middle Canyon Formation, Mission Canyon
Limestone, and McKenzie Canyon Limestone of the Tendoy Group; the
Kibbey...
This study demonstrates the utility of combining available scientific data with local ecological knowledge in a Geographic Information System (GIS) to support
community-based fisheries management. The approach used provides both the framework for capturing important ecological, economic and social information relevant to marine fisheries management, and also offers coastal citizens...
Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
