Chimney

This is a protruding object extracted from the ocean floor that is shaped like—and is known as—a "Chimneys." There are places on the ocean floor where magma rises up, where new ocean floors are formed, and metallic mineral resources called "Chimneys" have been known to appear. "Chimneys" are outlets for hydrothermal fluids, and with a shape that lives up to its name, produces hydrothermal fluid blackened by metallic minerals. When "hydrothermal fluid," which is sea water that has penetrated beneath the ocean floor and is heated by hot magma, rises up again from the ocean floor, the metallic substances contained within the hydrothermal fluid is exposed to cold sea water, and causes a variety of metallic minerals to precipitate. With their wealth of gold, silver, copper, zinc, and other rare metals, "Chimneys" are attracting attention as a future mineral resource.
