Mineral deposit - Hydrothermal solution | Britannica

Mineral deposit - Mineral deposit - Hydrothermal solution: Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent. They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals.

Mineral Deposits | National Geographic Society

A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals
