Answer:
Veins
Explanation:
As magma cools, water dissolved in the melted rock rises and is forced into any available cracks in the top of the igneous rock or in formations above. Often this super-hot hydrothermal fluid contains dissolved metals, which are deposited in veins, filling cracks in the batholith or laccolith. Veins like these yield gold, silver, copper, and other valuable metals.
