•448 MR. H. KAY ON THE HALESOWEN SANDSTONE [Oct. I913, 



and the ' good Coal-Measure beds ' of the brook farther east as 

 identical with the similar beds found in the Lutley Valley, and as 

 s cut off .... by a fault which is an upcast to the south.' 1 As 

 already shown (pp. 445-47), the beds in question belong to the 

 Illey Group, and are separated from those of the Lutley Valley by 

 the full thickness of the Hasbury Group. It is worthy of note 

 that the Illey Group is confined to the area south of the line of 

 .flexure indicated. 



(2) Faulting. 



The Halesowen Sandstones range up to the boundary-faults of 

 the coalfield, and may therefore be presumed to underlie the strata 

 for some distance farther east and west. These faults are described 

 by Jukes in detail. 2 The remaining faults which affect the area 

 -occupied by the Halesowen 1 Series are : — 



(«) The Russell's-Hall Fault. — This also is fully described 

 by Jukes, who says that 



'at Coombs Wood .... it seemed as if the fault were there passing into a 

 sharp anticlinal curve.' (Op. cit. p. 151.) 



He notes that on Mucklow Hill it is rather a rude anticline than 

 a clean-cut fracture or fault, since Coal-Measure sandstones are 

 • seen which dip 3° eastwards on one side of it and 30° or 40° 

 south-westwards on the other. These sandstones, however, may be 

 identified as members of the Witley Group, and of the upper 

 4 Espley ' Hock of the Old-Hill Series respectively, since the former 

 consist of grey sandstones underlying the blue clays of the Bellevue 

 Potteries, and the latter underlie the purple marls seen in the 

 clay-pit farther down the hill. Consequently, it would appear that 

 there is still a very considerable fracture. 



(b) The Hayes Pault. — This is described by Jukes as 



' a fault [running] parallel to the Netherton anticlinal on the eastern side of it 

 from Careless Green' northwards. (Op. cit. p. 155.) 



The fault appears to intersect the anticline obliquely near The 

 Hayes, and this has led to the curious southward termination of 

 the anticline which is shown on the published maps. 



(c) The Cradle y -Park Fault. — A fault is visible in the in- 

 clined tramway-cutting at Oldenhall, and the dislocation extends 

 east-north-eastwards through Cradley Park, where the Thick Coal is 

 thrown down northwards for 15 yards. 3 Still farther in the same 

 direction is the fault crossing Colman Hill to Corngreaves Hall 

 .(p. 439). The sandstones of the Witley Group are thrown down
