Stratigraphy And Structure Of The Goajira Peninsula, Northwestern Venezuela And Northeastern Colombia, John F. Rollins Jan 1965

Stratigraphy And Structure Of The Goajira Peninsula, Northwestern Venezuela And Northeastern Colombia, John F. Rollins

University Studies (University of Nebraska) (1888–1984)

The Goajira Peninsula forms the northernmost extension of continental South America (see Fig. 1). Its lobate outer portion, the area of this geologic study, is a mountainous region about 75 kilometers wide at its widest part and juts 150 kilometers northeastward into the Caribbean Sea. Although only about 110 kilometers north of the city of Maracaibo, Venezuela, the Peninsula is isolated and little known. Only a narrow coastal strip lies in Venezuela; the remainder is in Colombia; but the Peninsula is largely a desert wasteland not extensively entered by people other than its own sparse Indian population. Its remoteness has …

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen Jan 1965

Revision Of The Classification Of The Pleistocene Deposits Of Nebraska, E. C. Reed, V. H. Dreeszen

Conservation and Survey Division: Faculty and Staff Publications

The first major contribution of the Conservation and Survey Division to Pleistocene stratigraphy was that of A. L. Lugn (1935) who established a classification of the periglacial deposits of the state and related these deposits to the glacial stages. G. E. Condra and E. C. Reed (1950) used information aquired during the 1935-1950 period in making important revisions to Lugn's classifications. This report was a further revision based on studies made from 1950 to publication date (1965).

Stratigraphic Analysis Of The Queen And Grayburg Formations, Southeastern Chaves County, New Mexico, James L. Mcswain May 1963

Stratigraphic Analysis Of The Queen And Grayburg Formations, Southeastern Chaves County, New Mexico, James L. Mcswain

Earth and Planetary Sciences ETDs

The area of study lies in southeastern Chaves County, New Mexico, and is a part of the northwest shelf or backreef province of the Permian Basin. The area encompasses all or parts of Tps. 10 through 15 S., Rs. 24 through 31 E.

The Queen and Grayburg formations comprise the lower part of the Artesia group, an upper Guadalupian sequence of Permian shelf rocks above the San Andres formation and below the Ochoan series. The Queen-Grayburg sequence has an average thickness of about 600 feet and is correlative with the Goat Seep reef at the margin of the Delaware Basin, …


Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson May 1963

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd Mar 1962

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd

Publications (WR)

The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.

This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
/="/">the risk that may arise if ground water should …
