places along the line Tvhere the Lower Iveuper abuts against the 

 older rocks, the base of the subdivision becomes very coarse and 

 pebbly. At Nuneaton (Midland Company's Quarry and Tuttie 

 Hill Quarry) the well-bedded brown sandstones and red marls of 

 the Lower Xeuper rest horizontally upon steeply-dipping Hartshill 

 Quartzite. Farther south, at Wash Lane and again near Marston 

 Jabet, the unconformable junction of the Lower Keuper with the 

 Stockiugford Shales may be seen in several old quarries. At each 

 of the above-mentioned localities the junction is marked by a local 

 breccia, which consists of large angular fragments of the underlying 

 Cambrian rocks. 



At Black atree Farm, a quarter of a mile soutli-west of Wash- 

 Lane Bridge, iSTuneaton, a sand-pit and coal-shaft have proved the 

 Coal Measures dipping steeply south-westwards under 12 feet of 

 Lower Keuper Sandstone and red marl, which dip at lo'^ north- 

 eastwards. Again, a number of collieries from Hawkesbury to 

 Binley have proved that the horizontal Lower Keuper here rests 

 upon Coal Measures dijjping steeply westwards ; and between 

 ]S uneaten and Coventry the Lower Keuper overlaps in turn each 

 of the subdivisions of the Coal Measures. N'.ear Willenhall Bridge, 

 2 miles south-east of Coventry, a well and boring for water gave 

 the following section : —

The Permian was said to dip at about 15°, while the Lower 

 Keuper was nearly horizontal. Still farther south, the latter 

 rests upon liigher horizons of the Permian until Warwick is 

 reached. 



The unconformity betw^een the Trias and the Palaeo- 

 zoic rocks is thus one of 1 1 1 e ni o s t conspicuous features 

 in the geology of Warwickshire.
