Ore formation refers to the set of geological processes that concentrate economically valuable metals and minerals into ore deposits at grades significantly above average crustal abundance. It encompasses magmatic, hydrothermal, sedimentary, metamorphic, and weathering-related mechanisms that mobilize, transport, and precipitate metals in response to changes in temperature, pressure, redox state, fluid composition, and structural permeability. Key processes include magmatic segregation, hydrothermal fluid circulation and vein formation, exhalative deposition on the seafloor, chemical precipitation in basins, and supergene enrichment. Understanding ore formation is central to mineral exploration, genetic deposit modeling, and quantitative assessment of resource potential in diverse tectonic environments.
Researchers from Trinity College Dublin's School of Natural Sciences have revealed a novel route to the formation of bastnäsite, a crucial mineral for the extraction of rare earth elements (REEs). Their work offers promise ...

Why are gold deposits found at all? Gold is famously unreactive, and there seems to be little reason why gold should be concentrated, rather than uniformly scattered throughout the Earth's crust. Now, an international group ...
