Like almost everything else, Dwarf Fortress's geology is in a class of its own. There are about two dozen stone types that form layers, divided quasi-realistically into sedimentary, igneous intrusive, igneous extrusive, and metamorphic [1]. Then there are forty other types of stone that occur as veins and pockets [2]… and then there are about twenty types of metal ore and 130 different types of gem!
