Lateral Facies Change
This locality is perhaps the best section to show lateral change in facies. Here the Inter-bank facies, which was depoisted in low energy conditions, can be seen in the tight v-shape as shown in red. .Both are very rich in crinoids, corals, bryozoans and foraminifera. Algae indicate water depths of less than 200m.
