Constraints On Present-Day Basin And Range Deformation From Space Geodesy, Jeffrey Lee, Timothy H. Dixon, Stefano Robaudo, Marith C. Reheis Aug 1995

Constraints On Present-Day Basin And Range Deformation From Space Geodesy, Jeffrey Lee, Timothy H. Dixon, Stefano Robaudo, Marith C. Reheis

All Faculty Scholarship for the College of the Sciences

We use new space geodetic data from very long baseline interferometry and satellite laser ranging combined with other geodetic and geologic data to study contemporary deformation in the Basin and Range province of the western United States. Northwest motion of the central Sierra Nevada block relative to stable North America, a measure of integrated Basin and Range deformation, is 12.1±1.2 mm/yr oriented N38°W±5° (one standard error), in agreement with previous geological estimates within uncertainties. This velocity reflects both east-west extension concentrated in the eastern Basin and Range and north-northwest directed right lateral shear concentrated in the western Basin and Range. …

Geology Of The Ogallala/High Plains Regional Aquifer System In Nebraska: Field Trip No. 6, Robert F. Diffendal Jr. Apr 1995

Geology Of The Ogallala/High Plains Regional Aquifer System In Nebraska: Field Trip No. 6, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

This guide is mostly figures with a reference section containing some of the pertinent literature on the Cenozoic geology we will see over the next four days. We will make all 17 stops if the weather is reasonably good and the roads are passable. On the first day, April 29, we will try to get to stops 1–5, the more distal parts of the Ogallala and younger deposits in Nebraska. On April 30, we will try to visit stops 6–9. Stops 10–15, in areas closer to the sediment sources of the Ogallala and some of the younger units, will be …

Geologic Map Of Morrill County, Nebraska, James B. Swinehart, Robert F. Diffendal Jr. Jan 1995

Geologic Map Of Morrill County, Nebraska, James B. Swinehart, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Morrill County, Nebraska, is perhaps the most geologically interesting county in the panhandle of Nebraska. Surficial deposits of alluvium, colluvium, loess, and eolian sand of Quaternary age cover large parts of the county. Holocene and latest Pleistocene(?) eolian sand as much as 150 It thick covers much of the area north of North Platte Valley and mantles Quaternary alluvial deposits to the south. A thin veneer of loess overlies bedrock in the uplands of the southern part of the county. Alluvium underlies the valley floors and caps river and stream terraces. Two units of older Quaternary alluvium are exposed in …

Self-Study Report 1995

Conservation and Survey Division: Faculty and Staff Publications

This Self-Study Report for the Conservation and Survey Division (CSD) is a profile of the unit at this point in time. It is presented in three major sections: (1) Background; (2) Current Programs and Achievements; and (3) A Vision of the Future. All sections draw heavily upon documents, staff input, and committee activities going on within the division.


Rapid Uplift And Rotation Of Mylonitic Rocks From Beneath A Detachment Fault: Insights From Potassium Feldspar 40ar/39ar Thermochronology, Northern Snake Range, Nevada, Jeffrey Lee Jan 1995

Rapid Uplift And Rotation Of Mylonitic Rocks From Beneath A Detachment Fault: Insights From Potassium Feldspar 40ar/39ar Thermochronology, Northern Snake Range, Nevada, Jeffrey Lee

All Faculty Scholarship for the College of the Sciences

The thermal histories of mylonitic rocks from the footwall of the northern Snake Range decollement (NSRD), Nevada, were calculated using multiple diffusion domain analyses of potassium feldspar Arrhenius data and 40Ar/39Ar age spectra in order to characterize the cooling (exhumation) history of these mylonitic rocks and thereby constrain the origin and movement history of the NSRD. The calculated thermal histories, along with reported apatite fission track ages, indicate the three following episodes of rapid cooling (10–55°C/m.y.) related to extensional denudation: (1) middle Eocene (48–41 Ma), (2) late Oligocene (30–26 Ma), and (3) early Miocene (20–16 Ma). The …
