Three microfacies identified include; 1) Miliolid Lockhartia Mud-Wackstone Microfacies, interpreted to have been deposited in a low energy, restricted circulation with slightly higher than normal salinity in a lagoonal environment of the inner shelf, 2) Nummulitic Wack-Packstone Microfacies, representing deposition in a subtidal conditions of the carbonate shelf, 3) Benthic Foraminiferal Wack-Packstone Microfacies, interpreted to have been deposited in the middle shelf area relatively offshore.
