From the inseparable association with the igneous core there can 

 be no doubt that this peculiar agglomerate or breccia is due to 

 aeriform explosions by which the pre-existing crust was broken up 

 while the volcanic energy ceased without any appearance of the 

 uprising lava.

fissure itself. Possibly both of these channels of escape were in use, detached veuts 

 appearing at the east end, and a more continuous discharge from the fissure fm-ther 

 west. After the earliest explosions had thrown out a large amount of granitic and 

 Silurian detritus, andesitic lava rose in the fissiu'e, and, solidifying there, enclosed 

 a great deal of the loose fragmentary material that fell back into the chasm."
