112 ME. W. WICKHAM EING ON THE PERMIAN [Feb. 1899, 



failed to find any evidence of the existence of Middle Permian 

 conglomerate here. The three calcareous zones are well shown at 

 very many places, and can be followed as distinct ribs. They are 

 often crowded with small, rather angular chips and pebbles of pyro- 

 clastic rocks, with occasional limestone-pebbles. The fragments 

 rarely, however, exceed 1 or 2 inches in length, the largest that 

 I have found being one from Band A\ 4 inches long (Newtown). 

 In contradistinction to what takes place in the Enville district, 

 A^ is the thickest of the three bands. A", B^, &, C"^, following the 

 calcareous zones, are mainly composed of maris, but there are a few 

 local sandstones, which are, however, relatively insignificant when 

 compared with the corresponding bands of the Bowhills-Enville 

 district. 



The Upper Permian of the Clent Hills 



is made up of the trappoid breccia alone (D^). It occupies twO' 

 sub-districts : (i) that of the Clent Hills proper ; and (ii) that of 

 Ley Hill, Northfield. The latter will be considered when the 

 Warley-Barr district is described (p. 116). 



(i) The Clent Hills breccia extends from the Lower Lickey 

 Cambrian and pre-Cambrian rocks, and ranges north-westward 

 along the Clent Hills to Wychbury (see PI. XII). The outcrop is 

 6 miles long, and at its maximum more than a mile wide. 



This trappoid breccia is coarsest and thickest (450 feet) at 

 Walton Hill and Clent Hill. Here the basement-beds are made up 

 of a mixture of fine sandy and marly material, and of many small 

 fragments of angular breccia, varying in length up to about 

 9 inches. About 300 feet above the base there are many angular 

 blocks set in a marly paste : some more than 2 feet in length, many 

 more than 1 foot, and thousands from 5 to 6 inches. The highest 

 beds are finer than these, yet some fragments in them are 9 inches 

 long. 



The breccia of Clent Hill contains many large angular pieces of 

 Llandovery sandstone, some of which attain a length of 15 inches. 



2 b. The Stour Valley District. (Pi. XII.) 



Less than a mile from the north-western extremity of the Clent 

 Hills district, the Permian reappears at Chawnhill, near Stourbridge. 

 Its outcrop here forms a more or less continuous narrow (J mile) 

 strip, 4 miles long, extending to the vicinity of Kingswinford. 

 These beds are faulted against the Carboniferous on the east and 

 the Trias on the west, and the strip may be termed (i) the 

 Stourbridge-Kingswinford area. The Permian disappears 

 for 2 miles at, and north of, Kingswinford along the fault, but it 

 reappears between Baggeridge and Sedgley, where its outcrop covers 

 a tract between 1 and 2 miles square. This may be termed (ii) the 

 Baggeridge-Sedgley area.
