In:
Geological magazine : Vol. 95 Iss. 1-6 Year. 1958Summary: The field relations and petrography of the Grantown Newer Granite are described. The structure of the country rocks—Moine gneisses—is compared with that of the numerous blocks included in the granite, the results being synoptically presented. The blocks originally bore the same orientation as the country rocks and have been rotated in the granite during its emplacement. From east to west three zones of orientation, showing increasing rotation of blocks from their original position, are recognized in the granite. As the granite lacks an internal penetrative structure the kinematics of the blocks in the granite remains uncertain. All the evidence suggests that the granite did not form in situ, but was emplaced in a plastic state by dilation of the country rocks mainly along their foliation.
