Summary of the conclusions

The petrography of the Plateau Deposits has been determined. They yield species both of local origin and of the general Haldon types.

The kyanite and staurolite present have been derived from the north.

The planation of the limestones was initiated during the Cretaceous period.

The raised beaches are of slightly different types, the Thatcher raised beach being later. They furnish evidence of a former greater thickness of the Plateau Deposits.

Modern beach deposits furnish some evidence of the distributive powers of certain minerals, and point to the existence of Triassic and Cretaceous sediments outside the Bay.
