The chalk (h) rests unconformably upon the rocksbeneath, being seen lying upon the pre-Cambrian, theOld Red and the Carboniferous rocks, and in theoutlier in the north-west overlying the fault F2. From a study of the dip arrows it will be seenthat the Tertiary Basalt rests unconformably uponthe Chalk and also overlaps it to the southward onto the Old Red Sandstone.
