Abstract

Landsat 5 Thematic Mapper digital data covering the Coyote Spring Valley area of southeastern Nevada was enhanced to produce a false color composite image that highlighted lineaments. Lineaments were analyzed based on their statistical distribution and with correlations to geologic maps, regional geophysics (aeromagnetics and gravity) and field discontinuity data to produce a conceptual model of aquifer conditions of the southern White River Flow System. Lineaments were combined with geophysics to interpret large structures that delineate the basement of the regional carbonate aquifer. Whereas the C geophysics often provided the basis for interpretations, lineaments provided a mappable boundary that was unrecognized in the field and on small scale photographs. The extension of bedrock lineaments across alluvial basins identified underlying carbonate blocks that complicated the flow system. Field discontinuity data indicated the distribution of secondary porosity correlated with the distribution of lineaments; the lineaments provide an indication of the anisotropic properties of the carbonate system.
