WILMORE : THE STRUCTURE OF SOME CRAVEN LIMESTONES. 41 
further than is probable in the Gisburn district. There is an 
exposure just behind the first farm on the Settle highway, about 
quarter of a mile from Newsholme Station. Massive limestones 
dip X.X.W. at an angle of about 20°. Shale beds are very sub- 
sidiary. I have obtained only crinoidal debris here. 
Across the Ribble from Newsholme lies Paythorne. Here 
is a drift-covered country and exposures are few. A boring for 
water at Carholme Farm has been recently carried to a depth 
of 72 feet. 
25 feet drift (clay with grit and limestone boulders). 
47 feet dark soft shales. 
The shales are very fissile, micaceous, and very fossiliferous. 
I have got a good collection here. Amongst others the following 
are common : — 
Granatocrinus Derbiensis. 
ellipticus. 
Orthis Michelini. 
Strophomena rhomboidalis 
and crinoid stems and plates. 
The presence of granatocrinus would seem to place these 
strata in the Limestone Series. They are mapped as shales 
with limestones on the one-inch map. 
Further eastward we come to the somewhat dome-shaped 
mass which rises to 700 feet in the hills of Marton Scar. Here 
there is a departure from the simple anticlinal system of Chtheroe 
and Gisburn. Exposures are quite plentiful. 
A quarry is opened near the kennels on the Marton side 
of Gledstone Hall. The strata dip sHghtly S. of east at an angle 
of 30°. they are curiously folded over in one part of the quarry. 
Perhaps this is a surface disturbance due to glaciation. The strata 
are broken in the middle of the exposure but bent at the upper end. 
The succession is as follows : — 
Muddy shales with thin limestones, 6 feet. 
Limestone, 1 foot. 
Muddy shales, 1 foot 4 inches. 
Limestone, 1 foot 6 inches. 
Shale 4 inches. 
Massive hard, dark-blue limestone.
