Geothermal mineral formation is the process by which minerals crystallize, precipitate, or replace existing rocks through the circulation of hot, mineral-rich fluids generated by Earth’s internal heat. These geothermal fluids dissolve chemical elements from...

Mineral deposits are naturally occurring concentrations of valuable minerals or metals within Earth’s crust that can potentially be extracted economically. They form through a wide variety of geological processes including magmatic crystallization, hydrothermal...

Diagenesis is the collection of physical, chemical, and biological processes that alter sediments after deposition but before they undergo metamorphism. During diagenesis, loose sediments are transformed into solid sedimentary rocks through compaction, cementation,...

Sedimentary mineral formation is the process by which minerals are produced, transported, deposited, or chemically precipitated at or near Earth’s surface. Unlike igneous minerals that crystallize from magma or metamorphic minerals that form under high...

Metasomatism is the process by which the chemical composition of a rock changes due to the addition or removal of elements by chemically active fluids. Unlike ordinary metamorphism, which mainly changes a rock’s mineralogy through heat and pressure, metasomatism...

Mineral veins are sheet-like bodies of minerals that fill fractures, faults, joints, or cracks within rocks. Most veins form when hot, mineral-rich hydrothermal fluids circulate through the Earth’s crust and deposit dissolved minerals as temperature, pressure,...
