Most hydrothermal deposits form from hot, metal-rich fluids that are left during the late stages of the movement and cooling of magma.
Hydrothermal deposits are formed when hot water containing dissolved minerals rises to the surface and cools, causing the minerals to precipitate out and form a deposit. These deposits can occur in areas of volcanic activity or along tectonic plate boundaries where water can interact with hot rocks. Over time, the accumulated minerals can form valuable ore deposits such as gold, silver, and copper.

Can deposites of gold be found in deep ocean?
True!:)
What are hot fluids that can move through small cracks in rock?
Magma and hydrothermal fluids are hot fluids that can move through small cracks in rock. Magma is molten rock beneath the Earth's surface, while hydrothermal fluids are water heated by volcanic activity that can carry minerals and gases. Both can contribute to the formation of igneous rocks and mineral deposits.
What do ore deposits form from?
Ore deposits typically form from the concentration of ore minerals within Earth's crust through various geological processes such as hydrothermal fluids, magmatic segregation, or sedimentary accumulation. These processes involve the mobilization and concentration of valuable elements or minerals in specific areas, leading to the formation of economically viable deposits.
What ore deposits and gem crystals are often associated with?
Ore deposits are often associated with hydrothermal processes, where minerals are deposited from hot fluids circulating in the Earth's crust. Gem crystals are often found in igneous and metamorphic rocks, where the conditions for their formation are present, such as high pressure and temperature.
Is gold a common rockforming mineral?
No, gold is not a common rock-forming mineral. It is relatively rare and typically forms under unique geological conditions, such as in hydrothermal veins or placer deposits. Gold is most commonly found in association with quartz and sulfide minerals in ore deposits.

What are hydrothermal gold deposits?
Hydrothermal gold deposits are formed when hot, mineral-rich fluids rise from deep within the Earth and come into contact with cooler rocks near the surface. As the fluids cool and deposit their minerals, gold can accumulate in cracks and fractures in the rock, forming veins or deposits of gold. These types of deposits are found in association with volcanic or tectonic activity.
