USGS National and Global Oil and Gas Assessment Project—Zagros Fold Belt Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources of the Zagros Fold Belt Province. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is defined within the context of the higher-level total petroleum system. The assessment unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the total petroleum system, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The assessment unit boundary is defined geologically as the limits of the geologic elements that define the assessment unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. Machine-readable tables are provided that contain the input and results for each assessment unit summarized in the U.S. Geological Survey (USGS) Fact Sheet. Methodology of assessments are documented in USGS Data Series 547 for continuous assessments (https://pubs.usgs.gov/ds/547) and USGS DDS69-D, Chapter 21 for conventional assessments (https://pubs.usgs.gov/dds/dds-069/dds-069-d/REPORTS/69_D_CH_21.pdf).

LANDFIRE 2023 Succession Class (SClass) AK

LANDFIRE’s (LF) 2023 Succession Class (SClass) categorizes current vegetation composition and structure into up to five successional classes, with successional classes defined in the appropriate Biophysical Settings (BpS) Model. There are two additional categories for uncharacteristic species (exotic or invasive vegetation), and uncharacteristic native vegetation cover, structure, or composition. Current successional classes and their historical reference conditions are compared to assess departure of vegetation characteristics. The classification schemes used to produce BpS and SClass may vary slightly between adjacent map zones, and reference conditions may be simulated independently in different map zones for the same BpS.

Geospatial database for the spectral characteristics and mapping of lithium-rich playas in the Western U.S. Basin and Range (ver. 2.0, March 2025)

The data included here were used to evaluate the prospectivity for lithium in brines of playas of the western part of the Basin and Range Physiographic Province of the United States. Prospectivity is derived from the mappable criteria used in the descriptive deposit model published by Bradley and others (2013) and focused mainly from the remote sensing point of view. The playas in the study area have been ranked according to size (compared to Clayton Valley, the only area where lithium from brines is being produced in the country), the presence and abundance of source rocks, vegetation (as an indicator of water), reported prospects, and remote sensing data. The remote sensing products used are from data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor because it has regional coverage not available with other sensors.
New in this version: Four records in the Playas feature class ( and the corresponding shapefile and csv files) were modified, affecting the Prospects, Score, and Rank fields.

Portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver. 1.1, May 2025)

The dataset documents results from portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York.  Most of the pXRF samples were collected from representative cells in a series of five portable optically stimulated luminescence (OSL) grids, here denoted G1 through G5, to constrain variations in elemental abundances within the grids. These samples were also collected in conjunction with OSL for absolute chronology.
In the lab, pXRF analysis was conducted using a Bruker S1 Titan instrument housed in the Bascom Laser Diffraction Sedimentology Laboratory at the U.S. Geological Survey in Reston, Virginia.  Most of these samples were previously analyzed for particle size, and subsamples from G3 and G4 were also analyzed separately via inductively coupled plasma - mass spectrometry (ICP-MS) to further constrain elemental abundances.
This work is a collaboration with the Fort Drum Environmental Division and the Fort Drum Cultural Resources Division and was funded by the National Cooperative Geologic Mapping Program.
This Data Release was revised to v1.1 in May 2025 to correct the IDs and coordinates for three samples.  No other changes to the data release were made for v1.1.

PR_250M_AEA_NAD27.TIF - Puerto Rico U.S. EEZ GLORIA sidescan-sonar composite mosaic (ACEA, 250 m, Clarke1866)

From 4 November to 3 December 1985 the U.S. Geological Survey (USGS) conducted a single cruise to map the entire sea-floor of the Exclusive Economic Zone (EEZ) of Puerto Rico and the U.S. Virgin Islands. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the sea-floor. A total of 9 digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the U.S. Puerto Rico EEZ.

Topographic point cloud from UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA

This portion of the data release presents a topographic point cloud of the debris flow at South Fork Campground in Sequoia National Park. The point cloud was derived from structure-from-motion (SfM) photogrammetry using aerial imagery acquired during an uncrewed aerial systems (UAS) survey on 30 April 2024, conducted under authorization from the National Park Service. The raw imagery was acquired with a Ricoh GR II digital camera featuring a global shutter. The UAS was flown on pre-programmed autonomous flight lines spaced to provide approximately 70 percent overlap between images from adjacent lines, from an approximate altitude of 110 meters above ground level (AGL), resulting in a nominal ground-sample-distance (GSD) of 2.9 centimeters per pixel. The imagery was geotagged using positions from the UAS onboard single-frequency autonomous GPS. Survey control was established using temporary ground control points (GCPs) consisting of a combination of small square tarps with black-and-white cross patterns and temporary chalk marks placed on the ground. The GCP positions were measured using dual-frequency real-time kinematic (RTK) GPS with corrections referenced to a static base station operating nearby. The images and GCP positions were used for structure-from-motion (SfM) photogrammetric processing to create a topographic point cloud, a high-resolution orthomosaic image, and a DSM. The point cloud contains 284,906,970 points with an average point-spacing of one point every three centimeters. The point cloud has not been classified, however points with confidence less than three (a measure of the number of depth maps used to generate a point) have been assigned a classification value of 7, which represents low noise. The point cloud is provided in a cloud optimized LAZ format to facilitate cloud-based queries and display.

Ground control point locations and topographic GNSS measurements collected during the UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA

This portion of the data release presents topographic Global Navigation Satellite System (GNSS) measurements acquired during the UAS survey of the debris flow at South Fork Campground in Sequoia National Park.  The data contain the locations of the temporary ground control points (GCPs) used for the structure-from-motion (SfM) processing, as well as topographic measurements collected using a backpack-mounted GNSS rover. For the GCPs, 23 temporary points consisting of a combination of small square tarps with black-and-white cross patterns and "X" marks placed on the ground using temporary chalk were distributed throughout the survey area. For each GCP measurement the GPS receiver was placed on a fixed-height tripod and set to occupy the GCP for a minimum occupation time of one minute. For the topographic data acquisition, a GNSS rover was mounted to a backpack and used to collect continuous 1-second data on bare-ground surfaces of the debris flow site that were accessible on foot. The GNSS measurements were made using a real-time kinematic (RTK) GPS, with corrections from a GPS base station located on a temporary benchmark ("SFKW") established on the foot of the debris flow. The approximate base station position was initially derived using an autonomous position. The final coordinates for SFKW were derived using a seven-hour static occupation, submitted to the National Geodetic Survey Online User Positioning Service (OPUS-S). The resulting OPUS solution conforms to the quality standards for a USGS Level II single-base survey. After the survey was completed, the RTK data were adjusted using the final SFKW position using the Trimble Business Center software package. The GNSS data are presented in a comma-delimited text file.
