v0.31:Igneous extrusive layer

| This article is about an older version of DF. |
Igneous extrusive stone layers are formed from andesite, basalt, dacite, obsidian, and rhyolite. Of these five, andesite, dacite, and rhyolite are functionally identical, different only in appearance and name, basalt is like the other three with the caveat that it is magma-safe, and obsidian is... unique.
Their name appears dark gray on the embark menu.
- (In real world geology, igneous extrusive stone is formed by lava solidification on the surface, as opposed to igneous intrusive stone which forms below the surface. This is not true for Dwarf Fortress.)
