ABSTRACTPressurized brine reservoirs have been found in the Castile anhydrite which underlies the proposed Waste Isolation Pilot Plant. The major and minor component chemistry of the brines and the isotopic abundances of the brines and coexisting minerals have been determined and evaluated. Thermodynamic calculations indicate that the brines approach saturation with all major minerals in their host horizon. The brines therefore, appear to be in equilibrium with their geologic environment and do not have the capacity for substantially degrading the integrity of the site. When analyzed through solute versus bromide plots, the data indicate that the most likely origin for the brines is Permian seawater. As a result, the reservoirs appear to have been derived from waters no longer being introduced into the rock (i.e., they have a finite source).

Exploitation and utilization of coal resources will cause disturbances to the geologic environment and damages to the geologic environment conditions of the mining area, and lead to damages to ecological environment, formation of geologic hazards of mines and environmental pollution in the mining area. In this paper, current geologic environment of mines is investigated, and geologic environment problems of mines are assessed and prevention and control measures are researched on a basis of classified areas, with Dazhou, which is an important city in East Sichuan and where coal resources are rich and exploited frequently, as an example, to provide reference for protection, treatment and recovery of geologic environment of coal mines in East Sichuan.

Geologic Environment

A discussion is presented of the methodological approach to assessment of stability of geologic environment in regions where nuclear cycle objects are located. A basis of assessment is the registration of dynamics of variation of the various factors and exterior energy in a hierarchical block of geologic environment.

Geologic Environment

The Teton normal fault crops out along the eastern base of the Teton Range and relative motion across this fault has both uplifted the Teton Range and down-dropped Jackson Hole. On surface maps the normal fault appears to lie across older Laramide faults at a high angle, thus suggesting that previous structures had little to do with the position of the normal fault. Therefore, this field study was undertaken to test the following question: have preexisting Laramide or basement structures affected the position and/or geometry of the Teton normal fault? This question becomes important when considering the potential for contemporary earthquakes along the Teton normal fault and understanding the geologic environment of these earthquakes.
