Conservation and Survey Division: Faculty and Staff Publications

The inexperienced gemstone collector may sometimes think of Nebraska as being a place Mother Natural forgot. Mother Nature, however, may be enjoying a little chuckle at the many gem collectors who drive right through Nebraska on their way to more exotic gem fields.

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw Jan 1973

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw

Conservation and Survey Division: Faculty and Staff Publications

The Pierre-Niobrara unconformity, one of several significant unconformities in the Cretaceous System of the Western Interior region, has not generally been recognized. Detailed correlation of electric logs of a large number of wells in western Nebraska provides evidence of its existence. Isopach maps of the beds occupying three identifiable stratigraphic intervals - a redefined Niobrara Formation, an unnamed uppermost Niobrara unit, and an unnamed basal Pierre unit, which includes the Ardmore Bentonite - provide recognizable geologic patterns that permit reconstruction of the stages of development of the unconformity. The upper part of the Niobrara Formation has been truncated in several …
