Mineral Commodity Summaries 2024 - BISMUTH Data Release This data release contains the U.S. salient statistics and world production data extracted from the BISMUTH data sheet of the USGS Mineral Commodity Summaries 2024. Categories: Data; Tags: United States, bismuth, metal elements, metallic mineral resources Grade and tonnage data for disseminated flake graphite deposits Crystalline graphite is a primary material in lithium-ion battery anodes which are essential in moving towards green energy. Forecasts for 2040 anticipate an order of magnitude increase in graphite demand driven by sustainable development policies to reduce carbon emissions. Domestic production of graphite ceased in the 1980s after a steady decline post-World War I, meaning the United States relies on natural graphite imports from producers such as China or high-cost synthetic graphite. The current crystalline graphite flake model was released in 1992 and used 100 sites with graphite production. The updated grade and tonnage model uses 72 graphite sites with reports of flake graphite. The updated model implies economically...

This Web Map Service (WMS) has been developed to query data from the hydraulic models at select stream crossing locations using the StreamStats web application for Massachusetts. The WMS contains stream crossing point locations with hydrology and hydraulic data tables and associated watershed polygons. These stream crossing locations were...

Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis of selected physical and chemical properties. An atlas of microscopic images of biochar has been compiled by the Indiana Geological and Water Survey at Indiana University, Bloomington, IN, USA, containing more than 300 images contributed by researchers across the globe. USGS contributed 13 photomicrograph images from two biochar source...
