The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections under the U.S. Geological Survey's project titled "Quick Assessment of Rare and Critical Metals in Ore Deposits: A National Assessment" (2008 to 2013) in an effort to begin an assessment of the Nations' previously mined ore deposits for critical minerals. Mineralized and altered rock samples were provided by the Colorado...

For more than 25 years, the U.S. Geological Survey Gas Hydrates Project has compiled and maintained an internal database of locations where the existence of gas hydrate has been confirmed or inferred in research studies. The existence of gas hydrate was considered confirmed when gas hydrate was recovered by researchers or videotaped from a vehicle (such as a submersible or remotely operated vehicle) near the sea floor. The existence of gas hydrate was considered inferred when seismic data, borehole logs, or certain geochemical characteristics match anomalies known to characterize gas hydrate. This data release provides a text description of the region, geographic coordinates, and the citation for the published reference...
This data set is the digital geologic layer for the map of South Asia. The data set includes arcs, polgons, polygon labels, and attributes for geology, faults, inferred faults, and rivers. The data set is compiled from numerous UNESCO geologic maps to assist in the assessment of oil and gas for the World Energy Project.

Bottom simulating reflections (BSRs) are seismic features that are imaged in marine sediments using high-energy, impulsive seismic sources such as air guns or generator-injector guns. BSRs often cut across sediment stratigraphy and are interpreted as marking the deepest depth at which gas hydrate can exist. Gas hydrate is a naturally occurring and widely distributed frozen form of water and gas (usually methane) stable at low temperatures (up to about 25 degrees Celsius [°C]) and intermediate pressures (those that usually correspond to greater than 500 meters water depth). BSRs have been mapped in all the world’s oceans, in inland seas (such as the Black Sea), and in Lake Baikal in Russia. This data release consists...

This data release is a revision of the USGS National and Global Oil and Gas Assessment Project-Southeast Asia Assessment Unit Boundaries and Assessment Input Forms data release (DR-P9BI2N1N). Like DR-P9BI2N1N, this data release contains the boundaries of 48 assessment units and their respective assessment input forms and data. In addition, this data release contains the assessment results data, thereby placing all the information related to the assessment of undiscovered oil and gas resources in Southeast Asia in one publication. The results table in this data release is the source data for the assessment results found in Table 1 of FS 2020-3046. The Assessment Unit is the fundamental unit used in the National and...

This data release contains programmed pyrolysis, organic petrographic (reflectance), and semiquantitative X-ray diffraction mineralogy data for subsurface coal and shale samples from around the world. Samples were subjected to hydrous or anhydrous pyrolysis experiments at varying temperatures and the resulting residues were analyzed via programmed pyrolysis and reflectance to document changes in thermal maturity.
Illegal logging is one of the leading causes of deforestation today. Sadly, tree species indigenous to regions critical to maintaining Earth’s ecological diversity also possess properties (i.e. appearance, aroma, etc.) desirable to humans, which often leads to exploitation. In 1992, due to illegal logging, Brazilian rosewood (Dalbergia nigra) became the first ever tree species to be listed in an appendix of the Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES), which prohibited international trade of the timber or other products from this species between entities which had voluntarily joined CITES. Despite its inclusion in Appendix I of CITES, the species continues to be logged...
The Global Geochemical Database for Critical Metals in Black Shales (CMIBS) contains new geochemical data compilations for fine-grained sedimentary rocks in which each geologic material sample has one 'best value' determination for each analyzed species, greatly improving speed and efficiency of use (Granitto and others, 2013). The CMIBS was created and designed to compile and integrate geochemical data from seven continents in order to facilitate petrologic studies, mineral resource assessments and mineral exploration, definition of geochemical baseline values and statistics, environmental impact assessments, paleobiological studies and paleoenvironmental trends through Earth history. and studies in human health...

This data release presents the Yale stocks and flows database (YSTAFDB). Its data describe the use of 102 materials from the early 1800s to circa 2013 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. This data collection was previously scattered across multiple non-uniformly formatted files such as journal papers, reports, and unpublished spreadsheets. These data have been synthesized into YSTAFDB, which is presented as individual comma-separated text files and also in MySQL and PostgreSQL database formats. Consolidation of these data into a single database can increase their accessibility and reusability, which is relevant to diverse...
