Ore genesis

For example sedimentary exhalative deposits (SEDEX) are a class of ore deposit formed on the sea floor (sedimentary) by exhalation of brines into seawater (exhalative) causing chemical precipitation of ore minerals when the brine cools mixes with sea water and loses its metal carrying capacity Ore deposits rarely fit neatly into the categories in which geologists wish to place them Get price
