Sedimentary stone layers contain hematite, limonite, magnetite, tetrahedrite, bituminous coal, and lignite.
Chalk*, chert, claystone, conglomerate, dolomite*, flint, limestone*, mudstone, rock salt, sandstone, siltstone and shale layers are sedimentary.
- (* These also function as flux.)
The name of a sedimentary layer appears white on the embark menu.
Sedimentary layers are, on average, the most economically valuable of the four mineral layers. They are your only source of bituminous coal and lignite, vital for fueling non-magma forges and for the coke steel-making requires (especially if you lack trees). Even if magma is present, only sedimentary layers contain bauxite, the only stone (other than Hidden Fun Stuff) which can withstand the heat of magma. They are much richer in iron ores than other rock formations. Several sedimentary rocks - dolomite, chalk, and limestone - are fluxes, required for making steel making and also being twice as valuable as normal stone, making them useful for trade goods or furniture.
(In real world geology, sedimentary stone is formed by sediment. The sediment collects in constantly growing heaps and the pressure at the bottom eventually forms the sediment into stone. This is not true for Dwarf Fortress.)
