Excerpt: . . . appears to be no evidence of post-cretaceous submergence in this district, and it is difficult to determine the date at which the upheaval ceased. The most important representative of the Tertiary deposits is the Oligocene Brown Coal which occurs in depressions at various places on and around the Harz. A bed of workable brown coal, 50 feet in thickness, occupies a bay-like hollow in the core rocks immediately adjoining the line of fault at Wienrode between Thale and Blankenburg. The coal appears to cross the line of dislocation, and rest on the upturned edges of the Zechstein and Red Bunter sandstone in a way which seems clearly to show that the upward movement had entirely ceased before the agencies of denudation had hollowed out the depression subsequently filled up by the vegetable deposit. 10. Recapitulation. The area now occupied by the Harz Mountains was, during the Palaeozoic period, a portion of the great sea in which the Silurian, Devonian, and Lower Carboniferous rocks of Central Europe were deposited. The alternating greywackes, sandstones, shales, and limestones, with their accompanying fossils, indicate changes in the depth and condition of the water, but form throughout a perfectly conformable series. Volcanic action was vigorous in the Devonian period, when diabases and tuffs were emitted at various parts of the area Towards the close of the Lower Carboniferous period the sea shallowed, and deposition was finally arrested by the upheaval of the new-made rocks which were thrown into a series of violent folds, with a general N. E. and S. W. trend. The folding was followed by the irruption of great bosses of granite, after which the region was dislocated by a series of powerful faults which produced the fissures now filled by the. . .
