WebThe formation of hydrothermal ores is attributed to the hydrothermal solution or fluids that filter metals and minerals from the rock. These metals are then deposited into fracture and cracks within the rock called: veins. Fractures are a result of things such as water freezing and expanding. WebHydrothermal fluids flow into these spaces and form gold-bearing quartz veins. These fluids are created by hot, deeply buried metamorphic rocks. The Mother Lode and other deposits of the Sierra Nevada gold belt in California are examples. 6. Ancient gold deposits are found in greenstone belts: volcanic belts more than 2.3 billion years old.
