| Caption: | Permo-Triassic breccias - conglomerate, Okeover, Staffordshire. |
| Description: | Close-up of one of nine massive blocks of breccio-conglomerate up to 1.03 (bed thickness) x 2.0 x 1.1 metres which occur on the banks of a stream north of Okeover Hall and west of Kendar Wood. Angular sub-rounded pebbles and cobbles up to 22 cm. maximum dimension of altered Carboniferous Limestone, sandstone and siltstone are set in a reddish-brown, occasionally yellow, siltstone matrix. The whole is strongly cemented by calcite. The blocks clearly originate from the basal unit of the local Permo-Triassic sequence overlying the sub-Permo-Triassic unconformity. The Hercynian earth movements reached their climax in the Midlands soon after the deposition of the Coal Measures. The older rocks formed a mountainous tract that was subject to intense erosion and denudation, the magnitude of which can be seen throughout the Midlands by the strong unconformity and the occurence of conglomerates. |
