Print this pageABSTRACT: Environmental Applications of Basement Tectonics
GREGGS, DARCIE H., and R. G. GREGGS, Greggs and Asso., Geological Consultants Ltd., Calgary, Alberta, Canada
A brief overview of the recognition and development of basement tectonic principles will be presented. This survey describes theories of origin and presence of orthogonal fractures on other planets (Mars, Venus).
Various methods of determining the location, orientation, and magnitude of fractures are reviewed with selected examples from aerial photography, satellite imagery, aeromagnetic data, and geomorphological features as shown on standard topographic maps.
The environmental applications of basement tectonic concepts include determination of fluid movement through fractured rock and location of fracture-controlled river systems. The direction and depth of possible fluid movement and potential for movement along major fault systems are of major concern in location of landfill sites for toxic and nuclear waste disposal and location of nuclear plants, large dams, bridges, and major transportation corridors.
Case studies will be presented.
