Abstract

The granite quarries in a twenty mile radius of Aberdeen city, Scotland, were studied and petrofabric analyses made. The important structural features were (1) cross joints and the hard way of the rock in the plane striking 82 degrees east of north with a varying dip to the south, and (2) the plane of the biotite parallelism, longitudinal joints, and the easy way of the rock, in the plane (vertical at 13 degrees west of north) at right angles to the plane of the cross joints.
