VII. Notes on the Geology of the Ebbor-Rocks 

 District, near Wells. 



From the mouth of Ebbor Rocks, a picturesque little valley runs, 

 in a north-westerly direction, up into the hills. The geological 

 features of the immediate neighbourhood of this valley have received 

 considerable attention. 



According to the Geological Survey-memoir, 1 there is a puzzling 

 fault-complex in this locality, which may be briefly described as 

 follows. Millstone Grit occurs at the head of the valley, succeeding 

 conformably the Carboniferous Limestone on the north ; with the 

 former are associated carbonaceous shales. In the valley itself

occur Old Eed Sandstone and ' Lower Limestone Shales/ which are 

 succeeded conformably by the Carboniferous Limestone on the north, 

 but are faulted against Carboniferous Limestone on the south, and 

 against Millstone Grit on the west.
