Yol. 68.] ARDEN SANDSTONE GROUP OP WARWICKSHIRE. 261 



lies in a synclinal trough. In view of the unusual straightness of 

 this valley, and remembering that a fault is actually to be seen in 

 the railway-cutting east of the supposed plane of dislocation, I have 

 adopted the line on my map ; but the fault, if it exists, must be 

 of small throw, and soon dies out. 



(c) Henley-in-Arden to Tanworth-in-Arden. 



The River Alne, between Tanworth and Henley-in-Arden, has 

 cut through a low anticline of the Arden Sandstone, which caps a 

 good escarpment of the Lower Marls on the northern and eastern 

 sides of the valley but makes only a slight feature on the southern 

 and western slopes. My map of the ground bordering the escarp- 

 ment agrees substantially with the Geological Survey map and will 

 not therefore be discussed, but the other slope of the anticline has 

 not hitherto been mapped. South of the Leasowes, near Tanworth, 

 the Alne escarpment bends westward towards the river and sinks. 

 The sandstone crosses the river at this point, and its base can be 

 seen on the other side in an old marl-pit north of Robin Hood's 

 Farm, where it contains Estlierice and plant-remains. Between 

 this locality and Henley-in-Arden it is exposed at various places. 

 A fault was visible in 1907 during the construction of the new 

 railway, a short distance south of Danzey Green station, throwing 

 down the Upper Marls on the south-west against the Sandstone 

 zone. Another fault with a small downthrow to the east brings 

 in two small sandstone inliers near Impsley Farm. Another 

 north-west and south-east fault breaks the end of the anticline 

 at Blackford Hill, throwing down the sandstone on the south to 

 river-level, but it dies out in a short distance to the south-east. 

 A well-sinking at Blackford Corn Mill reached the top of the zone 

 at a depth of 8| feet. 



The sandstone reappears farther down the River Alne in the bed 

 of the stream at Wootton Wawen, and crops out on the main road 

 to Stratford-on-Avon and at other places in this locality. The out- 

 crop should perhaps be extended farther eastwards than is shown 

 on my map, but the rock is there buried beneath river-gravels. 



{d) Wixford to the Alne Hills and Morton Bagot. 



Near Stratford-on-Avon the Lower Liassic outcrop sends out a 

 lobe north-westwards in the direction of Aston Cantlow, where 

 it is further prolonged as two outliers with north-westerly axes. 

 Around these outcrops there is a good development of the Arden 

 Sandstone. 



At Wixford, 2 miles south of Alcester, the sandstone is found at 

 the level of the River Arrow (about 110 feet O.D.), and can be 

 traced thence without dijQ&culty, substantially as shown on the 

 Geological Survey map, through Oversley and Haselor to Aston 

 Cantlow. There is, however, aninlier not previously recorded, well 

 exposed at the village of Exhall between this line of outcrop and
