206 A. R. Horivood — Upper Trias of Leicestershire. 



Nottinghamshire border to Glen Parva in the south. South of this 

 point there is so much drift, and borings within the Liassic outcrop 

 have been so isolated or shallow, that there is a gap in our knowledge 

 of the intervening ground between the last point and the Rugby 

 district. The Countesthorpe boring, carried to a depth of over 600 feet, 

 encountered Upper Keuper beneath the Drift, with no intervening 

 Rhsetics. Commencing in the north in the Gotham district the two 

 outliers are capped above the ]led Marl and Tea-green Marl with 

 Rhaetic beds, and Lower Lias Limestone {Ps. planorhe zone) above. 

 At Ash Spinney at the soiith end of the southern outlier, and at 

 the east end of Crownend Wood, Black Shales with Avictda contorta 

 crop out; and on the west side septnria are seen. On the north-west 

 side of the northern outlier at Cottager's Hill ProtocardiumpMllipianiim 

 has been found in a well-section near the lane, lihsetic shales are 

 seen in the shafts driven for gypsum works about Gotluun. To the 

 south, at East Leake, in the railway cutting through Normanton 

 Hills at the south end of the tunnel, there was formerly a good 

 section showing Lower Lias and Rhsetics faulted against New Red 

 Marl, with a very sharp line of division, a continuation of the 

 Hoton fault, which is extended in a north-west direction to Castle 

 Donnington, between which two points the Soar Valley obscures 

 it ; but it cuts off the Lower Keuper at Hemington, bringing the Red 

 Marl to the surface. 



A section measured opposite the fault where the beds became more 

 horizontal showed : —
