WebHydrothermal ores are distinguished by their large number of component minerals. They are usually unevenly distributed in the contours of ore bodies, forming alternating zones of … WebThe mineral that forms is determined by what the dissolved elements are. If the water has interacted with silica-rich rocks (e.g., sandstone), silica-rich minerals will form like Silica (SiO2)-based minerals : amethyst (quartz); or opal. Of these, only opal is non-crystalline (ordered blobs of gel less than a micron in diameter).

WebSep 27, 2024 · These minerals often give ocean vents their characteristic color. Not all vent fluids are violently ejected into seawater from hydrothermal vents, however. Diffuse flows form in areas where vent fluids mix with cold seawater before exiting the seafloor. Diffuse flows usually cover a larger portion of a vent field than narrow hydrothermal vents. WebJun 8, 2024 · Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth’s crust through fractures. They eventually create metallic-rich fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals. grammy rap album of the year 2021
