Note that the veins or clusters can spread into other layers, and may cause some layers to contain stones they usually wouldn't.

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. Stones found on this table will occur as pockets and veins inside their respective stone layers (see above). These types of stone occur as entire layers, containing some veins and pockets of other minerals (see below). you won't find limestone in a marble layer.) The primary types of rock only occur in their own layers. The types are sedimentary layers, igneous intrusive layers, igneous extrusive layers, and metamorphic layers. 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. There are four types of stone layers (plus soil, which is not stone). If you are having the opposite problem, and find yourself running out of stone, try making stone blocks. Having created loose stone, most of the time you'll want to get rid of it, or at least move it someplace else. Bituminous coal and lignite can be reserved for making coke. For ores, this is smelting, and for fluxes, this is steel production. Few of these have a use outside of items and structures ( obsidian being a notable exception).Įconomic stones are types of stone that can be reserved for a special purpose. Rough gems: rough gems can be cut, then used to encrust objects and create windows.Ore: stones that produce metal bars when smelted.

Loose stones are divided into a few key categories: Other types of minable tiles include soil, sand, and clay these tiles do not produce loose stones when mined. Mining a rock tile leaves behind a loose stone (or just 'a stone') roughly 25% of the time. An unmined rock or stone tile is a naturally occurring solid aggregate of minerals.
