Thirty-four ore, twenty-nine mine waste, seven host rock, two pegmatite, and one slag sample were collected from iron oxide-apatite (IOA) mines in the eastern Adirondack Highlands near Mineville and Ticonderoga, New York, from March 2016 to August 2018. The waste pile samples included twenty-five samples collected from rubble-sized mine waste piles and four samples from processed tailings piles. The ore from historic iron mines of the eastern Adirondack Highlands, New York, contain abundant quantities of rare earth element (REE)-bearing apatite crystals. These apatite crystals are especially enriched in Y, La, Ce, and Nd. In-ground ore, mine waste piles, and tailings piles could contain apatite...

The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead within the workings to preclude drainage out of the mine. To understand the processes occurring during water impoundment within the mine workings, the U.S. Geological Survey (USGS), in cooperation with EPA, completed water-quality sampling and analysis during 2020 as water was impounded within the mine workings. The USGS sampling...

This study focuses on providing a broad-scale assessment of composition of water chemistry in urban stormwater runoff. The stormwater runoff is a source of recharge to groundwater by Green Infrastructure (GI) practices or it may become a source of recharge to groundwater to reduce stormwater volumes to surface waters or augment groundwater supply. The chemical composition of the stormwater runoff is important to understanding the potential impacts of surface water recharge to groundwater. In this study, 21 field sites were sampled for stormwater runoff during 50 storm events from 7/28/2016 through 12/8/2017. Major elements were measured by inductively coupled plasma-optical emission spectrometry and trace elements...

The Ankeny, Iowa wastewater treatment facility (WWTF) was decommissioned in November 2013 providing a unique opportunity to characterize the impacts of WWTF discharge on water quality at the surface-water/groundwater interface in a shallow, unconfined alluvial aquifer. The Ankeny WWTF discharged treated effluent for nearly forty years into Fourmile Creek, located in Ankeny, Iowa. Dataset includes site information (Table 1), analytical methods (Table 2), piezometer water level elevations (Table 3), trace and major element concentrations collected from 2011 to 2013 before the WWTF shutdown (Table 4), and trace and major element concentration collected from 2013 to 2014 after the WWTF shutdown (Table 5).

This U.S. Geological Survey (USGS) data release contains analytical data from a suite of rock and mineral samples collected from drill core within the Elk Creek alkaline complex, southeast Nebraska. This complex hosts the Elk Creek carbonatite, a multilithologic carbonatite enriched in niobium, rare earth elements (REEs), scandium, and titanium. Mineralized carbonatites are the world’s primary source of rare earth elements (REEs) and niobium, but only a few deposits are responsible for meeting the current demand of these critical elements such that there is increasing interest in other carbonatites that have the potential to help meet future demands. This study focuses on the Elk Creek carbonatite, the largest...

Central Asia, site of the historic Silk Road trade network, has long been a conduit for the movement of people, energy, and mineral resources between Europe and Asia. Once part of the former Soviet Union, this region was and continues to be an important producer of base and precious metals, rare metals (RM), including niobium, tantalum, and beryllium, and a past producer of rare earth elements (REE). The Tien Shan and Pamir Mountains regions, encompassing parts of Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, and Turkmenistan, are of significant interest for mineral exploration as these regions are thought to host substantial undeveloped and undiscovered resources of REE and RM. Based on this legacy, and as an...

This data set compiles the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) at Bokan Mountain, located in the southern part of Prince of Wales Island, southeastern Alaska. Bokan Mountain was formed by an Early Jurassic peralkaline igneous complex that intruded into lower Paleozoic rocks of the Alexander terrane of southeast Alaska. The pluton and surrounding country rocks host numerous mineral deposits and occurrences, including heavy rare earth element (HREE)-rich pegmatites and felsic dikes, as well as mineral deposits rich in uranium, thorium, HREE, and fluorine. The Ross-Adams mine on Bokan Mountain exploited a uranium-thorium deposit intermittently from the late...

In response to Executive Order 13817 of December 20, 2017, the U.S. Geological Survey (USGS) coordinated with the Bureau of Land Management (BLM) to identify 35 nonfuel minerals or mineral materials considered critical to the economic and national security of the United States (U.S.) (https://pubs.usgs.gov/of/2018/1021/ofr20181021.pdf). Acquiring information on possible domestic sources of these critical minerals is the rationale for the USGS Earth Mapping Resources Initiative (Earth MRI). The program, which partners the USGS with State Geological Surveys, federal agencies, and the private sector, aims to collect new geological, geophysical, and topographic (lidar) data in key areas of the U.S. to stimulate mineral...

Critical Minerals,
Energy Resources,
There is a growing demand for commodities (elements, compounds, minerals) used in today's advanced technologies. Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. The National Geochemical Database on Ore Deposits: Legacy data (NGDOD) contains chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Geochemical data sets from various mineral deposits were submitted by geologists of the "Systems Approach to Critical Minerals Inventory, Research, and Assessment" (SACM) within the U.S. Geological Survey Mineral Resource Program (MRP). The data sets represent...

Economic Geology,
The Trans-Pecos region of West Texas and Southern New Mexico contains a series of rare earth element (REE) enriched ~ 34-36 Ma intrusive rhyolites and syenites. One such intrusive in the Sierra Blanca Mountains, Texas, hosts the Round Top REE deposit which is one of the few REE deposits in the U.S. with an economic evaluation and is scheduled to go into production in 2025. In addition, Alkaline igneous rocks in the Cornudas and Hueco Mountains, both within the Trans-Pecos area, also show high concentration of REEs and other critical elements. In early 2021 an aeromagnetic and aeroradiometric survey was flown over the Trans-Pecos region with the following objectives: 1) Detect regional trends, fractures, or patterns...
