Fig. 13.— Diagram of fault and thin layer of coal, on left bank of river near Trombow. 



To the south is massive white sandstone, and the fault itself is 

 occupied by purple amygdaloidal trap or lava, and crushed black calcined 

 looking shale, amongst which some cindery fragments may represent 

 portions of the adjacent carbonaceous bed. The throw of the fault 

 appears to be to the south, but the amount is not determinable. 



The little seam of coal in the carbonaceous shale here varies in 



width up to two inches, and seems to die out within 



a few feet on each side ; it is bright and brittle, the 



largest fragments obtainable soon breaking down into minute pieces ^ 



a rough attempt to ignite it upon the spot "was but partially successful. 



•The associated shale is full of small plant remains of the usual striated
