    Learning Geology Ore forming processes

    Sep 17, 2014 Hydrothermal vein deposits are formed when these hydrothermal solutions enter a country rock along cracks and fractures. It precipitates in the parent rock in a vein like structure. The hydrothermal solution in vein deposits can also soak through the country rock which for disseminated ore deposits.This is less concentrated but as formed with the vein together they form economical deposit.
