Where Can Valuable Mineral Deposits Such As Gold Form?
Gold may occur as deposits called lodes or veins in fractured rock. It may also be dispersed within Earth’s crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks picking up gold and concentrating it in new locations in the crust.

Where are mineral deposits formed?
Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools the magma and ore carried within it crystallize to form tiny minerals in the newly-created igneous rock.
Where is gold ore found around the world?
