Glacial Chronology Of The Ruby Mountains–East Humboldt Range, Nevada, William J. Wayne Jan 1984

Glacial Chronology Of The Ruby Mountains–East Humboldt Range, Nevada, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

The Ruby Mountains-East Humboldt Range, one of the interior mountain groups of the Basin and Range Province, lies about midway between the Wasatch Mountains and the Sierra Nevada. After Blackwelder’s description in his review of glaciation in the western mountains, Sharp mapped and named the deposits of the Lamoille and Angel Lake glaciations and correlated them with early and late Wisconsin deposits of the Great Lakes area. The refinement of relative dating (RD) methods, the availability of air photos and modem topographic maps, and new road cuts have aided the restudy of these alpine glacial deposits and the basis for …

Hydrochemical Data For The Truckee River Drainage System, California And Nevada, Larry V. Benson Jan 1984

Hydrochemical Data For The Truckee River Drainage System, California And Nevada, Larry V. Benson

United States Geological Survey: Staff Publications


Abstract

Surface-water samples were collected from the Truckee River drainage system during 1975, 1976, and 1981. Data resulting from chemical analyses of these samples, as well as certain other previously unpublished data, are tabulated in this report. The report contains the following hydrochemical data:

1. Chemical composition of 21 tributaries to Lake Tahoe and the Truckee River upstream from Farad, California (May and October 1971, and June 1972).

2. Chemical composition of the Truckee River at Tahoe City (January 1968-January 1975) and at Farad, California (January 1968-June 1980), and of the Little Truckee River upstream from Stampede Reservoir, California (January …


Megaclasts In Alluvial Fills From The Ogallala Group (Miocene), Banner, Kimball, And Morrill Counties, Nebraska, Robert F. Diffendal Jr. Oct 1983

Megaclasts In Alluvial Fills From The Ogallala Group (Miocene), Banner, Kimball, And Morrill Counties, Nebraska, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Locally derived blocks and boulders (megaclasts) occur in conglomerate and in sand and gravel fills of channels in the Ogallala Group (Miocene) at localities in Banner, Kimball, and Morrill counties in western Nebraska. Some of the megaclasts are up to one or more orders of magnitude larger than the largest distantly derived grains in the sediments surrounding them. A number of these megaclasts probably moved downslope by mass wasting from outcrop sites on paleovalley sides and were later transported by running water. Other blocks and boulders were eroded by streams from bedrock along channel sides and then were transported by …

An Irvingtonian Fauna From The Oldest Quaternary Alluvium In Eastern Pumpkin Creek Valley, Morrill And Banner Counties, Nebraska, R. George Corner, Robert F. Diffendal Jr. May 1983

An Irvingtonian Fauna From The Oldest Quaternary Alluvium In Eastern Pumpkin Creek Valley, Morrill And Banner Counties, Nebraska, R. George Corner, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Vertebrate fossils of Mammuthus meridionalis (Nesti) and Equus sp. cf. E. scotti Gidley occur at two sites in the capping alluvium of the highest strath terrace along the south side of Pumpkin Creek Valley, Nebraska. The presence of these two species supports the conclusion that the age of the capping sediments is probably early Irvingtonian (early Pleistocene).

Preface

The computer brightened the 1970s considerably by giving researchers a tool for storing, retrieving and manipulating electronically sizable blocks of literary material on a single subject. which would otherwise have cost researchers years of scholarly investigation to bring together. It was in such a propitious moment mat we set out to assemble this state bibliography as an aid to scholars, researchers. scientists, teachers, writers, editors, and decision makers in the earth sciences, universities, and all levels of government.

As we collected, compiled, and checked citations for this bibliography, we relied heavily on the following standard sources that have indexed …

Asymmetrical Distribution Of Quaternary Alluvial Fills, Pumpkin Creek Drainage Basin, Western Nebraska, Robert F. Diffendal Jr., R. George Corner Jan 1983

Asymmetrical Distribution Of Quaternary Alluvial Fills, Pumpkin Creek Drainage Basin, Western Nebraska, Robert F. Diffendal Jr., R. George Corner

Robert F. Diffendal, Jr., Publications

A remnant alluvial fill of early Pleistocene age exposed in Pumpkin Creek Valley, Banner and Morrill counties, Nebraska, has yielded fossils of Mammuthus meridionalis (Nesti) and Equus sp. cf. E. scotti Gidley. Younger fill remnants of trunk and tributary streams allow a refinement of earlier views on the development of the Pumpkin Creek drainage basin during the Quaternary Period. Ancestral Pumpkin Creek both shifted to the north and entrenched its valley several times during the Quaternary Period leaving alluvial fills at three levels or more south of the present creek. Piracy of the headwaters of ancestral Pumpkin Creek took …

Chemical Composition Of Ground Water And The Locations Of Permeable Zones In The Yucca Mountain Area, Nevada, Larry Benson, J. H. Robison, R. K. Blankennagel, A. E. Ogard Jan 1983

Chemical Composition Of Ground Water And The Locations Of Permeable Zones In The Yucca Mountain Area, Nevada, Larry Benson, J. H. Robison, R. K. Blankennagel, A. E. Ogard

United States Geological Survey: Publications

Ten wells in the Yucca Mountain area of southern Nevada have been sampled for chemical analysis. Samples were obtained during pumping of water from the entire well bore (composite sample) and in one instance by pumping water from a single isolated interval in well UE-25b#1. Sodium is the most abundant cation and bicarbonate the most abundant anion in all water samples. Although the general chemical compositions of individual samples are similar, there are significant differences in uncorrected carbon-14 age and in inorganic and stable-isotope composition. Flow surveys of seven wells performed using iodine-131 as a tracer indicate that ground-water production …

A Hydrochemical Reconnaissance Study Of The Walker River Basin, California And Nevada, Larry Benson, R. J. Spencer Jan 1983

A Hydrochemical Reconnaissance Study Of The Walker River Basin, California And Nevada, Larry Benson, R. J. Spencer

United States Geological Survey: Staff Publications

During 1975 and 1976, a large number of water and sediment samples were collected from the Walker River Basin. Additional surface water samples were collected during 1980 and 1981. Data are given herein for chemical analyses of snowmelt, tributary, river, spring, well, lake, reservoir, lake sediment pore fluid, tufa, lake and river sediment samples. These data provide the basis for consideration of processes which govern the chemical evolution of large closed basin hydrologic systems in the Basin and Range Province of the Southwestern United States.

The Walker River Basin, a part of the Basin and Range Province, is located i~ …

Gully, Scour Hole, And Pothole Development At The Base Of The Gering Formation (Miocene?), Southeastern Banner County, Nebraska, Robert F. Diffendal Jr. Sep 1982

Gully, Scour Hole, And Pothole Development At The Base Of The Gering Formation (Miocene?), Southeastern Banner County, Nebraska, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Several sediment-filled paleovalleys belonging to the Arikaree Group of Miocene (?) age occur in southeastern Banner County, Nebraska. One gully and a main paleovalley exhibit, respectively, erosional features like those in modern gullies in the area and like those on the bedrock floors of modern straight streams carrying an appreciable sediment load. Scour holes and a pothole on the valley floor of the main paleovalley are similar to those produced experimentally on the bed of a straight stream.
