This article is about an older version of DF.

(For the beginning player, see also Template:L)



Stone or rock is a naturally occuring solid aggregate of minerals. It sometimes Template:L material after being mined or Template:L. Other types of Template:L tiles include Template:L and Template:L.

Stone is divided into a few key categories:

Template:Ls are types of stone that can be reserved for a special purpose. For Template:Ls, this is smelting and for Template:L, this is steel production. Template:L and Template:L can be reserved for making Template:L.

Having created loose stone, many times you'll want to get rid of it or at least move it someplace else. See Template:L for advice.

This article is about DF geology and the distribution of stones, and does not contain the specific locations of Template:Ls or Template:Ls.

Main layer types

Main article: Layer

There are four types of stone Template:Ls (plus Template:L, which is not stone). The type of layer is the primary indicator of what kind of Template:Ls you are likely to find on the map, as well as a sign of Template:L activity.

The types are Template:Ls, Template:Ls, Template:Ls, and Template:Ls.

The primary types of rock only occur in their own layers. (e.g. you won't find Template:L in a Template:L layer.)

Stones forming entire layers

These types of stone occur as entire layers, containing some Template:L of other minerals (see below). If one of the following types of stone is present on your map, it will be listed in one of the Template:Ls on the embark screen.

Template:L Template:L Template:L Template:L


(* These stones are practically identical within the game, distinguished only by their names and their un-mined presentation on the map. See Template:L for the sole minor difference.)

Other Stone

Stones found on this table will occur as Template:L inside their respective stone layers (see above). When your miners newly encounter one of them, the game will pause and you will receive an announcement; even for the ones that have no use other than to build constructions of unusual colors. Note that the veins or clusters can spread into other layers, and may cause some layers to contain stones they usually wouldn't. A few of these stones, such as Template:L, have other, more interesting minerals appear inside them.

Non-layer stone formations occur in one of three shapes: large clusters, veins, and small clusters. (See Template:L for full info.)

The following table does not contain Template:Ls and Template:Ls. The types of stone listed here that do not link to their own article are generic.v0.28.181.40d

DF Geology and real-world Geology

The geology and stones of Dwarf Fortress are based on real-world geology and mineralogy. To understand the terms used here, you may want to crack open a geology textbook (a high school one should suffice). If you don't happen to have one close by, the Wikipedia articles for geology, mineralogy, or the terms in question might help.
