<p>Mek42: Added footnote in introduction denoting which stones are magma-safe.</p> <hr /> <div>{{av}}{{Quality|Exceptional}}<br /> '''Sedimentary stone layers''' contain [[hematite]], [[limonite]], [[magnetite]], [[tetrahedrite]], <br /> [[bituminous coal]], [[lignite]], and [[gypsum]].<br /> <br /> [[Chalk]]*, [[chert]]**, [[claystone]], [[conglomerate]], [[dolomite]]*, [[limestone]]*, [[mudstone]], [[rock salt]], [[sandstone]]**, [[siltstone]] and [[shale]] layers are sedimentary.<br /> :&lt;sup&gt;(* These also function as [[flux]]. **These are also [[magma-safe]].)&lt;/sup&gt;<br /> <br /> 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]] [[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]].<br /> <br /> 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 &quot;Find Desirable Location&quot; 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 &quot;Find Desirable Location&quot; function as it will sometimes list green sites that have flux stone but it will not indicate that it does, actually, have flux stone.<br /> <br /> (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.)<br /> <br /> ==Sedimentary layers==<br /> {{Layerlookup/layers|SEDIMENTARY}}<br /> <br /> ==Stone found in sedimentary layers==<br /> {{Layerlookup/stones|SEDIMENTARY}}<br /> <br /> ==Gems found in sedimentary layers==<br /> {{Layerlookup/gems|SEDIMENTARY}}<br /> <br /> &lt;small&gt;* See also: [[stone found everywhere]]&lt;/small&gt;<br /> <br /> {{stones}}<br /> {{Category|Stone Layers}}</div>
