术语速记:
术语 "石材(stone)" 可以指两个不同但相关的概念,这取决于你在讨论 "石材" 或者 "石料"。当将其称为一般材料时, 它包括所有非有机材料,而不是特定的土壤金属宝石,如“岩层主要是花岗岩”或“为工坊腾出空间而挖出的石材”。 当提到石料, 即采矿时留下的圆形物体时,它是指运送到某类型工坊的原材料,或可原样用于建造的具体对象,而这个圆形物品既可以是石材(在第一种意义上),也可以是宝石或某种金属矿石,如“剩下的石材大多是花岗岩和一些黄金”或“挖出的石料必须被搬走,以便为工坊腾出空间”。通常在上下文中很明显,要么是1:一般的非矿石/非宝石物品,要么是2:可被运走的一单位石材/矿石/宝石————只是为了清楚起见。

未开采的岩石石材图块是自然存在的固体矿物质聚集体,开采岩石图块大约有25%的时间会留下松散的石材(或者说是“石料”),其他类型的可开采图块包括土壤,沙子和黏土;这些图块在开采时不会产生松散的石材。

松散的石材分为以下几种主要类别:

  • 矿石冶炼之后产生金属的石材
  • Rough gems: rough gems can be cut, then used to encrust objects and create windows.
  • Other stone: all other stones. Few of these have a use outside of items and structures (obsidian being a notable exception).

Economic stones are types of stone that can be reserved for a special purpose. For ores, this is smelting, and for fluxes, this is steel production. Bituminous coal and lignite can be reserved for making coke.

Having created loose stone, most of the time you'll want to get rid of it, or at least move it someplace else. See stone management for advice.

If you are having the opposite problem, and find yourself running out of stone, try making stone blocks.

Main layer types

主条目:Stone layers

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

The types are sedimentary layers, igneous intrusive layers, igneous extrusive layers, and metamorphic layers.

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

Stones forming entire layers

These types of stone occur as entire layers, containing some veins and pockets of other minerals (see below).

沉积岩 侵入火成岩 喷出火成岩 变质岩
- 耐熔岩

Other Stone

Stones found on this table will occur as pockets and veins inside their respective stone layers (see above). When your miners newly encounter one of them 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 橄榄岩, 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 Veins & Clusters for full info.)

DF Geology and Geology in Real Life

The geology and stones of Dwarf Fortress are based (to some extent) 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. Below is a very brief introduction tailored for DF gamers, with links to the relevant game-specific pages.

In geological terminology, a rock or stone is basically a composite of minerals. Minerals, the building blocks of rock, are hard inorganic materials with a definite chemical formula and a certain atomic structure. For example, the mineral quartz is composed of silicon dioxide (SiO₂) arranged in a pyramid structure. Quartz is a component mineral of rocks (stones) such as quartzite (almost entirely made of quartz) or granite (some 20~60% quartz, a bunch more of the mineral "feldspar", plus mica and some others). The distinction between minerals like mica (simple) and rocks like granite (composite) does not matter for Dwarf Fortress; just like in everyday language, they're all just "stones". Besides minerals, some rocks may include organic material; such rocks include bituminous coal (made of dead bog things) or limestone (made of the skeletons of ocean animals).

The three minerals seen in granite are also among the most common:

  • Feldspar, meaning something like "field-stone", is actually a general name for an entire family of minerals, all of them based on aluminum and silicon. Their appearance varies, but they tends toward light greyish colors, and make up a lot of your typical light stone. Feldspar doesn't exist independently in the DF world; but, among the in-game stones, microcline and orthoclase are flavors of feldspar, and countless other DF stones would include feldspar in real life. A stone with a lot of feldspars and silicon is said to be felsic; granite and rhyolite are in-game examples.
  • Quartz, meaning "hard", easily makes big showy crystals; it's transparent if pure, but if the SiO₂ is combined with trace amounts of other elements (often metals like iron and manganese), it can get colored pink, purple (amethyst), yellow (citrine), and so on. If bubbly with air, quartz may become milky; if irradiated, it may get smoky.
  • Micas, like quartz, have silicon atoms crystalline structures. The difference is that they're organized in sheet-like, gleaming surfaces, held together by weaker bonds of other elements; this makes micas soft and flaky (the word means "grainy"). The color varies. The in-game stone mica is stated to be muscovite, which is a light variety (but the game color is dark gray, like coal; this may be a mistake). Other micas can be dark.

Other minerals that exist independently in DF include green olivine (yes, it's named after olives) and black hornblende, which is similar to dark mica but forms needlelike crystals. Dark minerals like these often include magnesium and iron (Fe); stones rich in them are then termed mafic (in contrast with "felsic"). In-game mafic stones include basalt and gabbro.

On the white side, calcite is a mineral based on calcium, the same stuff as bones. It forms crystals, and occurs in DF as an unremarkable white stone. Calcite is a main component of limestone and chalk—which in turn can become marble; it's often formed from the accumulated remains of ancient marine animals (for a memorable use of chalk stone layers in high fantasy, check out Terry Pratchett's novel The Wee Free Men and its sequels). The most well-known marine mineral is surely table salt, present in DF as rock salt. It's formed when saltwater evaporates; another evaporative mineral, or "evaporite", is gypsum, which, in DF as in real life, can be used to make plaster casts

Rocks can be classified by their creation processes, which makes them settle down in distinct stone layers, and possibly in veins and clusters. DF models this too, so that it's quite relevant information for players; see the links for details.

An ore is a rock with a metal content high enough for it to be a viable source of that metal. Most metals do not occur by themselves in nature, but readily bind with minerals to form stones; e.g. zinc binds with sulfur minerals to form the rock sphalerite. To extract the metal from it, someone has to smelt the stone. A few metals may be found in pure form, like native gold and silver (but in DF, they still require smelting to be shaped into useable bars).

A gem is a mineral (or rock, or rock-like material) with intrinsic economic value for a culture, often because they're beautiful, durable, and/or rare. This depends not just on what the mineral is made of, but also on the internal layout of its atomic structure, which can dramatically alter its appearance and properties; see the article on gems for more.
