PERMIAN STRATA OF EAST CHESHIRE. 



225 



coui'se east from Torkington, we find the following series^ in 

 the descending order, all the beds dipping westward : — 



Permian beds .. 



Coal-measures . . . 



tc , 



- 1. Red Marls. 



2. Soft red breccia, a sandy matrix containing angtdar 

 fragments of coal-measure grits, shales, and pieces 

 of earthy haematite. 



3. Soft purple grits, red shales, with bands of earthy 

 haematite. 



Owing to the amount of drift over this part of the 

 country, it is impossible to examine the exact northern and 

 southern limits of this little outlier of Permian beds." 



As it is desirable to collect all the sections showing the 

 relation of the Permian strata to the underlying Coal- 

 measures, probably we may be excused for bringing this 

 portion of Mr. HulFs labours before the Society. The 

 section is exposed in a small brook- course called Ockley 

 Brook, flowing between the Green Clough and Blackwood 

 farms on the estate of Mr. Legh, of Lyme, about a mile a 

 little south of east from the Hazel- Grove railway-station. 



Ockley-Brook Section. 



1. Drift. 2. Red clays (Permian). 3. Breccia. 4. Soft red sandstones 

 and red and variegated shales. 5. Middle Coal-measures. 



When I lately examined the section, only about one 

 hundred yards of the strata were exposed. They occurred 

 in the following descending order : — 



1. Brown Till. 



2. Permian beds. . . Red marls. 



( Red breccia, chiefly composed of Coal-measure sand- 

 j stones, some of them two inches in diameter, for the 



3 ^ most part quite angular, with small pieces of quart;^, 



[ quartzite, and haematite, in a paste of sandy clay 

 \^ about ten yards in thickness.
