So why is gold found in veins? Isn't it weird that all this dead-star juice clumps together? It isn't formed by the Earth. So it just got deposited in clumps? (lemmy.dbzer0.com)

Hydrothermal processes play a crucial role in bringing gold closer to accessible depths. These processes involve the movement of hot fluids through the Earth’s crust, dissolving and transporting minerals, including gold, along the way. These fluids could be molten lava in a volcanic area.

When these mineral-laden fluids encounter cooler conditions or suitable host rocks, they deposit the dissolved gold. This can lead to gold deposits or veins forming in various geological settings, such as quartz veins, which are common hosts for gold. The intricate dance of temperature, pressure, and chemical reactions orchestrates the creation of gold deposits that await discovery.
