'''Sedimentary''' [[stone layers]] contain [[hematite]], [[limonite]], [[magnetite]], [[tetrahedrite]], [[bituminous coal]], [[lignite]], and [[gypsum]]. [[Chalk]]*, [[chert]]**, [[claystone]], [[conglomerate]], [[dolomite]]*/**, [[limestone]]*, [[mudstone]], [[rock salt]], [[sandstone]]**, [[siltstone]] and [[shale]] layers are sedimentary.
:<sup>(* These also function as [[flux]].  **These are also [[magma-safe]].)</sup>

Sedimentary layers are, on average, the most economically valuable of the four [[stone layers]].  They are your only source of [[bituminous coal]] and [[lignite]], vital for fueling non-[[magma]] forges and for the [[coke]] that [[steel]]-making requires (especially if you lack [[tree]]s).  They are much richer in [[iron]] [[ore]]s than other rock formations.  Several sedimentary rocks - [[dolomite]], [[chalk]], and [[limestone]] - are [[flux]]es, required for [[steel]]-making and also being twice as valuable as normal stone, making them useful for [[crafts|trade goods]] or [[furniture]].

Sedimentary layers can be tricky to locate - if you are starting off, and you want access to an embark area with sedimentary layers, use the "Find Desirable Location" function before embark and set your parameters to include sites with [[flux]] stone. Since most flux stones are found in sedimentary layers, this will increase your chances that a suitable site will have sedimentary rock near the surface. Be careful when using the "Find Desirable Location" function, as it will sometimes list green sites that have flux stone but not indicate that it does, actually, have flux stone. To find iron ores, search for a location that has shallow metals, flux stone, medium elevation, and either high or low drainage. On large maps, the ore is sometimes located near mountains and major rivers in large (min ~10x10) chunks.

Alternatively, a [[mountain]] biome that has an [[aquifer]] is guaranteed to be sedimentary as well, due to mountains lacking soil, which means the aquifer must be in sedimentary layers.

If your [[Embark#Changing_Views|embark civilization]] has access to sedimentary layer stones [[Embark#Prepare_Carefully|when preparing]], it is likely one or more of the biomes in their sites overlap a biome containing it.

(In real-world geology, sedimentary [[stone]] is formed by sediment, which gets carried away by rivers and deposited in constantly-growing heaps, where the pressure at the bottom eventually forms the sediment into stone.)
