| Description: | Triassic Kidderminster Formation at Marlbrook Gravel Pit, Marlbrook Quarry. Looking north-north-east. Conglomerate, with interbedded sandstone band, at base of Kidderminster Formation, Sherwood Sandstone Group. This basal conglomerate is composed of pebbles and cobbles in a weakly cemented matrix of coarse, micaceous, moderately well-rounded sand. Most of the clasts are well-rounded 'Bunter' quartz and quartzite pebbles and cobbles. The jointed pebble right of the hammer is a Dinantian, Lower Carboniferous chert. In each bed the pebbles generally coarsen downwards, and the lower bed here is not far above the Clent Breccia. The Kidderminster Formation was formerly called the Bunter Pebble Beds. It consists of a sequence of fluvial (river deposited) sandstones and conglomerates. It attains a thickness of of up to 375 metres. It is thought that the conglomerates were deposited by a major river flowing from the Hercynian Highlands to the south. |
