This article is about an older version of DF.

Igneous intrusive stone layers can consist of granite, diorite, or gabbro, all of which typically contain gold and tetrahedrite.

Gabbro can also contain garnierite, the ore of nickel, kimberlite, which may contain diamonds, and olivine, which may contain native platinum. Granite can contain cassiterite, the ore of tin, bismuthinite, the ore of bismuth, and galena, the ore of lead. Galena will also give you a silver bar 50% of the time.

(In real world geology, igneous intrusive stone is formed by lava solidification occurring below the surface, as opposed to igneous extrusive stone which forms above the surface of the earth. This is not true for Dwarf Fortress.)
