This dataset includes wavelength dispersive X-ray fluorescence (WD-XRF) major-oxide and trace-element whole-rock analyses, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) trace-element whole-rock analyses, and glass analyses by electron microprobe of scoria and lava samples from the Kamakaiʻa Hills of the Southwest Rift Zone of Kīlauea volcano, Island of Hawaiʻi. Whole-rock chemical analyses were performed at the Hamilton Analytical Laboratory at Hamilton College in Clinton, New York, USA, whereas glass chemical analyses were performed at the U.S. Geological Survey in Menlo Park, California, USA.

Groundwater, soil pore water, and surface water were collected in and near wetland P1 in the Cottonwood Lake Study Area, Stutsman County, North Dakota in August 2013. Groundwater was collected from established wells (17, 18, and 22) via peristaltic pump. Surface water was collected from P1 ponded water via grab sample. Soil pore water was collected using drive point samplers and one suction lysimeter. Water samples were analyzed for pH and major ion chemistry.

The U.S. Geological Survey is studying uranium and associated trace element bioaccumulation in aquatic invertebrates across a gradient of dissolved uranium concentrations in spring outflow pools and creeks in the Grand Canyon and adjacent watershed. This data release makes available data from sampling campaigns in April 2016, April 2017, and in April 2019. Data collected include: (1) major ion, trace element and dissolved organic carbon in surface waters of spring outflow pools and streams; (2) concentrations of uranium and other trace elements in bed sediment, periphyton, and larva of aquatic insect taxa; (3) uranium and iron extraction data from a subset of bed sediment samples, and (4) X-ray diffraction data...

This data release compiles major and trace element analytical results of samples of bauxite (aluminum ore) and associated rocks collected from the Arkansas bauxite region, located near the center of Arkansas in Pulaski and Saline Counties. Samples were collected by the U.S. Geological Survey (USGS) in April 2018 as part of the USGS' focus on increased understanding of the United States' critical mineral resources. Mineral commodities, based on USGS studies, have been designated as critical where the United States is predominantly reliant on foreign sources (McCullough and Nassar, 2017; Fortier and others, 2018). The five primary aluminum smelters in the U.S., in 2017 and previous years, were dependent on imported...

At 11:21 p.m. (Hawaii Standard Time [HST]) on November 27, 2022, Mauna Loa volcano on the Island of Hawaiʻi started erupting from fissures at its summit caldera, Mokuʻāweoweo. This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is denoted as ‘South Caldera,’ with the exception of a short fissure that extended into the uppermost Southwest Rift Zone. By November 28, activity had shifted to four fissures that opened in the upper Northeast Rift Zone (Lynn and others, 2023). By December 2, eruptive activity was focused from Northeast Rift Zone fissure 3A supplying lava...
