[Silver, copper, lead and zinc] form compounds with sulphur, called sulphides. Deep in the Earth's crust, where it is very hot, salty water(called brine) circulates and dissolves these metals, collecting them up and concentrating them in the hot brine.... Sometimes, on the sea floor, this brine comes up through the surface out of holes we call vents. When the hot brine comes into contact with the cold sea water the metal sulphides cannot stay dissolved and precipitate onto the sea floor as various minerals.  2, record 29, English, - hot%20brine
