The evidence for neotectonic activity will be studied through the investigation of changes in stream channel morphology, review of geologic literature and oil company exploration logs, and the use of National Geodetic Survey first order releveling data. These three data sources will allow corroboration of interpretations from independent sources of information. Primary objectives of this proposed study are: identify stream and/or drainage basin morphology causally related to neotectonic activity for a variety of river types, provide mutually supportive geomorphic and geodetic data to establish evidence of crustal instability, establish regional patterns of neotectonic activity, establish relations between surface morphology and subsurface structures, and determine if differential compaction of sediments that are draped over sub-surface highs have effects on surface morphology similar to those of neotectonics. Results of this investigation could lead to an efficient and dependable procedure for recognition and quantification of crustal instability, and for recognition of geologic structure.The potential commercial application as described by the awardee: This information is of very practical significance to economic geologists and to those who must choose sites for nuclear facilities and major water resource projects. In addition, the techniques developed will serve as an adjunct to other types of exploration for oil and gas. The procedure will serve as a guide for geophysical exploration and drilling that will result in substantially reduced exploration costs.
