  • gem formation: how are gemstones created?

    gem formation usually involves mineral crystallization and other geological processes. rather, they form from fluids that escape from it, such as gems from hydrothermal deposits and pegmatites. first, we'll cover two exceptions to this process: magma and gas crystallization. the international gem society (igs) is the world's top

  • hydrothermal alteration of basaltic rocks at eruptive

    the study of changes in rocks due to interaction with hydrothermal fluids at active volcanoes provides insights into wall rock alteration associated with ore deposits formed in the geological past. therefore, the nature of mineral alteration and chemical changes experienced by wall rocks can be investigated at eruptive sites on active volcanoes and the results used to better constrain ore
