Principal facts for 408 gravity stations in the vicinity of the Talkeetna Mountains, south-central Alaska Principal facts for 408 gravity stations in the vicinity of the Talkeetna Mountains, south-central Alaska

Gravity data were collected between 1999 and 2002 along transects in the Talkeetna Mountains of south-central Alaska as part of a geological and geophysical study of the framework geology of the region. The study area lies between 61° 30’ and 63° 45’ N. latitude and 145° and 151° W. longitude. This data set includes 408 gravity stations. These data, combined with the pre-existing 3,286...

Principal facts for gravity stations in the Dry Valley area, west-central Nevada and east-central California Principal facts for gravity stations in the Dry Valley area, west-central Nevada and east-central California

In June, 2002, the U.S. Geological Survey (USGS) established 143 new gravity stations and 12 new rock samples in the Dry Valley area, 30 miles north of Reno, Nevada, on the California - Nevada border (see fig. 1). This study reports on gravity, magnetic, and physical property data intended for use in modeling the geometry and depth of Dry Valley for groundwater analysis. It is part of a...

Preliminary soil-slip susceptibility maps, southwestern California Preliminary soil-slip susceptibility maps, southwestern California

This group of maps shows relative susceptibility of hill slopes to the initiation sites of rainfall-triggered soil slip-debris flows in southwestern California. As such, the maps offer a partial answer to one part of the three parts necessary to predict the soil-slip/debris-flow process. A complete prediction of the process would include assessments of “where”, “when”, and “how big”...

Geochemistry of Permian rocks from the margins of the Phosphoria Basin: Lakeridge core, western Wyoming Geochemistry of Permian rocks from the margins of the Phosphoria Basin: Lakeridge core, western Wyoming

The Permian Phosphoria Formation and interbedded units of the Park City Formation and Shedhorn Sandstone in western Wyoming represent deposition along a carbonate ramp at the eastern margin of the Phosphoria Basin, with portions of the Phosphoria units reflecting periods of upwelling and widespread phosphogenesis. Thickness-weighted slab-samples of these units were collected at a maximum...

Correlation of the Klamath Mountains and Sierra Nevada Correlation of the Klamath Mountains and Sierra Nevada

This report graphically portrays the broadly parallel tectonic development of the Klamath Mountains and Sierra Nevada from early Paleozoic to Early Cretaceous time. It is dedicated to J.S. Diller of the U.S. Geological Survey who, during his pioneer field studies a century ago, recognized significant similarities between these two important provinces. The report is based mainly on the...

Chapter D: With or Without Salt-a Comparison of Marine and Continental-Lacustrine Diatomite Deposits Chapter D: With or Without Salt-a Comparison of Marine and Continental-Lacustrine Diatomite Deposits

Diatoms in sedimentary deposits of marine and continental, especially lacustrine, origin have similar nutrient (for example, phosphate, nitrate, and silica) and light requirements; however, their geologic ranges and physiographic environments vary. Marine diatoms range in age from Early Cretaceous to Holocene, and continental diatoms range in age from Eocene to Holocene; however, most...

Studies by the U.S. Geological Survey in Alaska, 2001 Studies by the U.S. Geological Survey in Alaska, 2001

The collection of 14 studies that follow continues the series of U.S. Geological Survey (USGS) investigative reports in Alaska under the broad umbrella of the geologic sciences. This series presents new and sometimes-preliminary findings that are of interest to Earth scientists in academia, government, and industry; to land and resource managers; and to the general public. The reports...
