170 Mr. De la Beche on the Geology of Tor and Babbacomhe Bays, Devon. 



torted limestones before mentioned, and is probably the cause of their present 

 appearance. 



I consider that the whole disturbance of this district, is attributable to the 

 causes that produced the trap, — causes which probably also occasioned all those 

 faults and contortions here so common. What the g-eological date of this 

 event may be, it Avould be difficult to say, as we have no stratified rock resting- 

 peaceably on the trap. That this rock was here intruded after the formation 

 of Exeter red conglomerate, is probable from reasons before assigned, and I 

 feel disposed to connect the disturbance of the Tor Bay district with the 

 catastrophe that elevated the strata in the line of Weymouth and the Isle of 

 Wight, and caused the contortions and faults so common on the coast; — a 

 catastrophe perhaps corresponding iii date with that which raised the great 

 range of the Alps.
