Age of the Aliwal Shoal, South Africa


SPECIMENS of calcareous sandstone containing foraminifera from the submerged Aliwal Shoal, about 5 km east of Green Point on the Natal coast, 50 km south of Durban, were received from Mr. M. J. McCarthy of the University of Natal. They have been investigated with a view to determining the age of the rock. The first specimen was obtained from the damaged bow of the ship Aimee Lykes following a collision between this ship and the Shoal. Later, a larger specimen was collected by a diver. The specimens were gently crushed to free the grains and, from the −28, +100 Tyler mesh fraction, all the foraminifera were picked out and mounted.
