Preliminary geologic map of the Murrieta 7.5' quadrangle, Riverside County, California Preliminary geologic map of the Murrieta 7.5' quadrangle, Riverside County, California
The Murrieta quadrangle is located in the northern part of the Peninsular Ranges Province and includes parts of two structural blocks, or structural subdivisions of the province. The quadrangle is diagonally crossed by the active Elsinore fault zone, a major fault zone of the San Andreas fault system, and separates the Santa Ana Mountains block to the west from the Perris block to the...

Geologic database for digital geology of California, Nevada, and Utah— An application of the North American Data Model Geologic database for digital geology of California, Nevada, and Utah— An application of the North American Data Model
The USGS is creating an integrated national database for digital state geologic maps that includes stratigraphic, age, and lithologic information. The majority of the conterminous 48 states have digital geologic base maps available, often at scales of 1:500,000. This product is a prototype, and is intended to demonstrate the types of derivative maps that will be possible with the...

Preliminary metallogenic belt and mineral deposit maps for northeast Asia Preliminary metallogenic belt and mineral deposit maps for northeast Asia
The metallogenic belts and locations of major mineral deposits of Northeast Asia are portrayed on Sheets 1-4. Sheet 1 portrays the location of significant lode deposits and placer districts at a scale of 1:7,500,000. Sheets 2-4 portray the metallogenic belts of the region in a series of 12 time-slices from the Archean through the Quaternary at a scale of 1:15,000,000. For all four map...

Geology of Badlands National Park: A preliminary report Geology of Badlands National Park: A preliminary report
Badlands National Park is host to perhaps the most scenic geology and landscape features in the Western Interior region of the United States. Ongoing erosion that forms the "badlands" exposes ancient sedimentary strata of Late Cretaceous through Oligocene age. Quaternary erosional and depositional processes are responsible for most of the modern landscape features in the park and...

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...

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...
