Investigation of the principal lineament at the Idaho National Laboratory
Technical Report
·
OSTI ID:5988582
The principal linament, a feature visible in aerial photographs of the eastern Idaho Engineering Laboratory, was investigated to determine whether or not the lineament was the surface expression of a fault. The investigations included: (a) a vegetation survey; (b) direct-current resistivity and time-domain electromagnetic resistivity geophysical surveys to explore for subsurface offsets; (c) trenching to look for near-surface offset; (d) soil stratigraphy; (e) outcrop mapping. These investigations allowed the construction of a geologic/geophysical cross-section that extended from the grass roots to a depth of approximately 2.5 km. There was no evidence that the principal lineament is associated with either near-surface or deep faulting. The lineament is a surface phenonenon posing no hazard to the nuclear facilities on the INEL. 19 references, 7 figures, 4 tables.
