How does a hydrothermal ore deposit form?

A. Hydrothermal ore deposits form in submarine volcanoes.
B. Hydrothermal ore deposits form where lava flows contact surface water.
C. Hydrothermal ore deposits form when groundwater dissolves minerals.
D. Hydrothermal ore deposits form due to hot water circulating through magma or rocks.



Answer :

Final answer:

Hydrothermal ore deposits are formed by hot, aqueous solutions flowing through crustal rock, depositing minerals like sulfides.


Explanation:

Hydrothermal ore deposits are formed when hot, aqueous solutions flow through fractures and pore spaces of crustal rock, depositing minerals such as sulfides. These deposits are often rich in ores like Cu, Sn, W, and some native metals like gold. An example of a hydrothermal deposit is the Jerome deposit in Arizona.
