Some of them probably belong already to the Miocene group. In the same manner the occurrence of iron ore is nearly every where connected with that of Brown-coal in the Westerwald, where the basaltic conglomerates lie flat and are in a condition of metamorphosis. Medleys of Red, Brown and Clayironstone appear as irregular strata or as balls in clay-beds. The occurrence of iron ores is very frequent in the Oligocene deposits between the Rheno-Westphalian and Hcrcynian mountains. They begin in the Duchy of Nassau on the southern side of the Taunus and are met with as far as Neudorf. Strata of Clay-iron and Brown-iron ores of 1 to 2' occur in Hesse-Darmstadt in the Cyrene-manls near Oberingelheim on the Rhine, and as sandy Brown-iron ores near Gambach and Reckenberg in the lower Oligocene beds. Extensive strata of sandy Brown-iron ores occur in Rhenish Hesse in the Litorinella-clays or the upper Oligocene beds, showing a thickness of 8 to l2', upon which deposits of brown and yellow pisolitic iron ores lie, 12 to 32' thick in gray and red clay. A continuation is found in the district of Hanan. In the Wetterau a layer of argillaceous Clay-ironstone is found above the uppermost Brown-coal seam. _ Brown iron ores appear in great quantity on the Basalt of the Vogelsberg, partly in a state of transition to Basalt, partly forming bunches under the diluvial loam and in the marl. Pisolitic iron ores occur also near Niedermollich; Brown-iron ores in the district of Hofgeismar, 26' thick; argillaceous Brown-iron ore, containing Man-ganese, as strata in the clay near Hohenkirchen and sandy Brown-iron ores near...show more
