This article is about an older version of DF.
Created from rocks that have crystallized from the heat of magma.

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, plus a 50% chance of silver).

In the real world

Igneous intrusive stone is formed by magma solidification occurring below the surface, as opposed to igneous extrusive stone, which forms above the surface of the earth.
