Gold is formed in the Earth's crust through a process called hydrothermal deposition. This occurs when hot water carrying dissolved gold and other minerals rises from deep within the Earth's mantle and interacts with rocks in the crust. As the water cools, the gold and other minerals are deposited in cracks and fissures in the rocks, eventually solidifying into gold deposits.
