Laser-ablation inductively-coupled-plasma mass spectrometry and electron probe microanalyses of pyrite and pyrrhotite in tailings and ores from volcanogenic massive sulfide and sedimentary-exhalative deposits Laser-ablation inductively-coupled-plasma mass spectrometry and electron probe microanalyses of pyrite and pyrrhotite in tailings and ores from volcanogenic massive sulfide and sedimentary-exhalative deposits
Mine waste, including mill tailings, could host substantial critical mineral resources. Developing an understanding of the mineral hosts and occurrence of critical minerals in mine waste is essential to evaluating their resource potential. Volcanogenic massive sulfide (VMS) and sedimentary-exhalative (SEDEX) deposits are important global sources of copper, zinc, lead, gold, and silver...
Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC, Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC,
These data are laboratory reflectance measurements conducted on a suite of altered mafic and ultramafic rocks. Visible-Near InfraRed (VNIR) and Short-Wave InfraRed (SWIR) reflectance measurements were made (~0.4 – 2.5 microns) using an artificial light source connected to an Analytical Spectral Devices (ASD) spectrometer. Spectra from a total of 91 samples were measured and analyzed...
Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023 Water and sediment geochemistry in the Gallinas Creek Watershed, New Mexico following the Hermits Peak-Calf Canyon fire 2022-2023
This data set was collected throughout the Gallinas watershed in New, Mexico following the Hermit's Peak-Calf Canyon fires on April 6, 2022. The watershed has a history of mining and prospecting, which acts as an additional stressor to post-wildfire water quality and ecosystem health. Water samples were collected immediately post-fire. Water, sediment deposit and bed sediment samples...
Historical nickel laterite regions and assay samples in southern Oregon and northern California, USA Historical nickel laterite regions and assay samples in southern Oregon and northern California, USA
This dataset consists of 529 areas of identified nickel laterite in southern Oregon and northern California, compiled in vector shapefile format from six historical publications from 1956 to 1983. Sources include state and federal projects for geologic mapping and critical mineral exploration purposes and are attributed to each polygon. Five original, georeferenced maps are included in...
Coal Exploration Drill-Hole Data for Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming Coal Exploration Drill-Hole Data for Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming
Coal exploration drill-hole data from 5,037 wells located in Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming are provided in this data release. The wells are located in sixty-eight counties and were drilled between 1971 and 1981, primarily by Phillips Petroleum Company (Phillips). The hard-copy paper data were donated to the U.S...
Data for Reaction Kinetics and Catalytic Effects of Sulfides in Early Mature Hydrocarbon Generation using Hydrous Pyrolysis Data for Reaction Kinetics and Catalytic Effects of Sulfides in Early Mature Hydrocarbon Generation using Hydrous Pyrolysis
This data release supports a study investigating the role of sulfur as a catalyst in thermal reaction kinetics, focusing on the effect of pyritic sulfur on early maturation and consequent hydrocarbon generation. Hydrous pyrolysis experiments were conducted on mixtures of gilsonite and pyrite in varying ratios. Untreated and thermally altered residues were analyzed for solid bitumen...
Total organic carbon and programmed temperature pyrolysis data with calculated thermal maturity parameters for Babouri-Figuil Basin samples Total organic carbon and programmed temperature pyrolysis data with calculated thermal maturity parameters for Babouri-Figuil Basin samples
The West and Central African Rift System (WCARS) refers to the series of Cretaceous rift basins where commercial hydrocarbon accumulations have been discovered. The Babouri-Figuil Basin (BFB) is an area of interest in terms of petroleum prospecting related to the WCARS. Many researchers have identified potential petroleum source rocks in the BFB. However, most of these studies have...
Data supporting nanometer-scale relationships between sedimentary organic matter molecular composition, fluorescence, cathodoluminescence, and reflectance Data supporting nanometer-scale relationships between sedimentary organic matter molecular composition, fluorescence, cathodoluminescence, and reflectance
This data release describes optical photothermal infrared (OPTIR) spectroscopy data used to map sedimentary organic matter functional group distributions at 500 nm resolution in a sample from the Lower Cretaceous Sunniland Limestone from the South Florida Basin. Examined fields of view include occurrences of amorphous organic matter (AOM), inertinite, micrinite, solid bitumen...

Insights into the formation of thucholites Insights into the formation of thucholites
Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...
