Stratigraphy Of The Inyan Kara Formation (Lower Cretaceous) In The Vicinity Of The Nesson Anticline, Northwestern North Dakota, Brad L. Wartman Jan 1983

Stratigraphy Of The Inyan Kara Formation (Lower Cretaceous) In The Vicinity Of The Nesson Anticline, Northwestern North Dakota, Brad L. Wartman

Theses and Dissertations

The Lower Cretaceous Inyan Kara Formation, at the base of the Dakota Group, consists of sandstone, siltstone, shale, and coal. The stratigraphy of the Inyan Kara and facies relationships within the formation and with the underlying Swift and overlying Skull Creek Formations in the vicinity of the Nesson Anticline, northwestern North Dakota, were evaluated using 11 cross-sections, 163 borehole geophysical logs, and 1 well core.

The Inyan Kara can be differentiated on well logs into three members. The basal member, "A", consists of sandstone, siltstone, shale, and coal. It is about 200 feet (60 m) to 400 feet (122 m) …


A Description Of The Soils And Geology Of The Berkshire Valley Experimental Catchment, M R. Wells, D J. Mcfarlane Jan 1983

A Description Of The Soils And Geology Of The Berkshire Valley Experimental Catchment, M R. Wells, D J. Mcfarlane

Resource management technical reports

Basic land resource data are provided in this report to assist an investigation of the effect of contour banking on surface runoff in the Berkshire Valley experimental catchement. Brief descriptions of the catchment's geology, soils and their inferred hydrological significance are provided and a 1:2000 scale map produced. Of major significance to the hydrologic study is the fact that soil depth and internal drainage conditions were found to be not related to landscape positions.
