mineral deposits on the seafloor

Hydrothermal mineral deposit Wikipedia

Skarn Mineral Deposits tend to be small in size but high in mineral grade. Therefore, it is a balance and challenge to find a profitable skarn orebody. Geologically speaking, a skarn deposit is an assemblage of ore and calcsilicate minerals, formed by metasomatic replacement of carbonate rocks in the contact aureole of a pluton.
