WebThe chimneys are made out of sulfide minerals that precipitate out of the vent fluid and can grow 10's of meters high. Many large ore deposits now found on land were formed at hydrothermal vents millions or even billions of years ago. Black smokers are an example of focused vents, in which almost all the vent fluid comes out of one small pipe.
