Petrology of a Wealden Sandstone at Clock House, Capel, Surrey

Published online by Cambridge University Press:  01 May 2009

Extract

The topmost band of sandstone in the Weald Clay at Capel (6) is now exposed for 100 yards, and varies in thickness from 8 inches at the southern end of the face to 1 foot at the northern end. The stone is glauconitic and highly micaceous, and carries so much fresh biotite on certain bedding-planes that they are heavily darkened. Flakes of biotite and muscovite commonly reach 2 mm. in diameter, and occasionally 3 mm. No petrological facies like it is known in the older Hastings Beds outcropping to the south and south-east. The petrography of the sandstone therefore merits description, and some discussion of the problems which it raises.
