Three-dimensional geologic model of Yucca Mountain, southern Nevada
There is a need within the Nevada Nuclear Waste Storage Investigations (NNWSI) project for a comprehensive three-dimensional description of the subterranean geology of Yucca Mountain, Nevada. The model that is described is an initial version of a three-dimensional geometrical representation that can provide centralized and consistent information to the various tasks in the project. The initial implementation of the model is a collection of surface representations - one surface for the base of each stratigraphic zone. The primary method of surface definition is an analytical interpretation technique called Trend Modulation by Multikernel summation. The method was developed at Sandia National Laboratories for use with sparse and irregularly distributed input data such as that provided at Yucca Mountain. Comparison of predicted and actual elevations of geologic contacts in drill holes not used as input data indicates that the method predicted the elevations at those drill holes to within 71 feet or less with 95 percent confidence. Four representative geologic cross sections are presented, with a brief discussion. Regional trends suggested by other researchers are seen in some of the cross sections. 19 references, 8 figures, 17 tables.
