Digital geospatial database for the Geologic map of the southern Stillwater Range, Nevada

This data set is a geospatial database for the 1:24,000 scale Geologic Map of the Southern Stillwater Range, Nevada (John and others, 2024). It contains all the geologic spatial information and text unit descriptions from the printed map, in the Geologic Map Schema (GeMS) format for digital geologic maps maintained by the USGS’ National Cooperative Geologic Mapping Program (NCMGP). Base map data a

Data Release for "Apatite and monazite geochemistry record magmatic and metasomatic processes in rare earth element mineralization at Mountain Pass, California"

The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate and carbonatite samples from which apatite and monazite were analyzed, as well as geochemical data collected via electron microprobe and laser ablation ICP-MS for the apatite and monazite mineral grains. Whole rock geochemical data were collected by SGS Labs, except carbonatite samples 84-6-1

Data for Distance sampling accounting for density gradient and animal distribution

There are 9 datasets. one distance sampling dataset, 4 resource selection datasets, and 4 outputs from bootstrapped resource selection models the use the estimated correction factor. The 4 resource selection datasets have data that can be used in a binomial generalized linear mixed effect model to create the correction factor. The distance sampling data set is used to estimate density, and the 4 r

Archive of the Hydrologic and Hydraulic Models used in the Analyses of the Silver Creek Basin and Selected Tributaries Associated with Scott Air Force Base, Illinois, 1992–2050

The U.S. Geological Survey (USGS), in cooperation with Scott Air Force Base (SAFB), Illinois, assessed the effects of temporal land-use development in the Silver Creek Basin, the potential effects of projected changes in future precipitation, and the effects of added detention storage in selected tributaries near SAFB. A hydrologic model was used to simulate precipitation runoff and streamflows fo

Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix

The Kingshill aquifer resides under St. Croix, an Island in the U.S. Virgin Islands. The Island of St. Croix is mountainous in the northwestern and eastern regions of the island and the central and southwest regions contain rolling hills and plains. The Kingshill aquifer underlies the plains of St. Croix. The aquifer is composed primarily of limestone and marl and has a maximum saturated thicknes

Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma, New Mexico

The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer is prim

Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada

The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption and cool

Aquifer framework datasets used to represent the Western Interior Plains aquifer system, Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Wyoming

The Western Interior Plains aquifer system is located in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming and covers an area of more than 220,800 square miles. The thickness of the aquifer system ranges from 500 feet in eastern Colorado (HA 730-D) to as much as 10,000 feet in western Oklahoma (PP_1414B). This aquifer system consists o

Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma

The Central Oklahoma aquifer underlies an area of about 2,900 square miles in central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and consists of Garber Sandstone and the Wellington Formation, which are part of the Sumner Group of Permian age. The maximum thickness of the aquifer is about 1,000 feet with a saturated thickness ranging from 150 to 650 feet.  The aquifer is

Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico

The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock aquifer consi

Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington

The Willamette Lowland basin-fill aquifers (hereinafter referred to as the Willamette aquifer) is located in Oregon and in southern Washington. The aquifer is composed of unconsolidated deposits of sand and gravel, which are interlayered with clay units. The aquifer thickness varies from less than 100 feet to 800 feet. The aquifer is underlain by basaltic-rock. Cities such as Portland, Oregon, d

Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma

The Ada-Vamoosa aquifer resides in the Central Lowland Physiographic Province in east-central Oklahoma and ends at the Kansas State line. The aquifer underlies an area of about 2,300 square miles. The aquifer consists mainly of layers of fine to coarse-grained sandstone irregularly interbedded with shale and limestone. The rocks are in the Ada and the Vamoosa Groups are Pennsylvanian age.
