Si-lurian schists, limestones, and sandstones occurabove them in these three ranges, and the east-em Sudeten, while the Rhenish Slate Moun- the low countrj at their base the deposition ofthe carboniferous formation took place. TheGerman Carboniferous belongs to the terres-trial facies of the period, the lower part(Culm) being shales and sandstones of litoralorigin with occasional coal seams (Hainichen,.Saxony) : the upper includes the productivecoal fields. They extend w-ith little interrup-tion from Belgium along the northern slope ofthe Rhenish Devonian into Wcstplialia (RuhrBasin), and with the fields around Saarhriickenfarther south, in Saxony (Zwickau), and Silesia(Waldcnburg, Myslowitz), are the most import-ant sources of coal supply in central Europe. The Permain consists of two epochs: Rot-liegendes and Zechstein. During the Rotlic-gonde the area remained land, the Paleozoic.•\lps were worn down to Mittelgebirg heights,. v^

Volcanic activity continued insome places (porphyrites and pitchstones ofSaxony). In the Zechstein epoch the oceanadvanced again, leaving its deposits on thenorthern edge of the Mittelgebirge, especiallyaround the Harz and in northern Thuringa.Among them arc the famous copper-bearingshales of Mansfeld, the Zechstein proper (shal-low water limestone), and the immense saltbeds of the upper Zechstein epoch (Stassfurt,Spercnberg) with their large supplies of gyp-sum and araum* salts. The Triassic period consisted of threeepochs in Germany. In the first a shallow seacovered especially western Germany, formingthe reddish sandstones (Buntsandstein) whichcover miles and miles from Basel to Osna-briick, the W. slope of the Eifel, the regionaround Tarnowitz in Silesia, and form the cliffsof Heligoland.
