| Lithology description: Packstone | |
| Environment: | perireef or subreef |
| Geology comments: This facies is frequently interbedded with the Rhodolith Pavement facies and commonly occurs as units up to 3.4 m in thickness. The unit is composed of massive, bioturbated beds. This sediment frequently forms the final deposit capping the bioherm. The principal grain type in the rock is coralline algal debris (28%). Echinoid fragments {1.4%) and entire rotaliid foraminifera (2.9%) are the only features which appear to be slightly better represented in this facies than in previous ones. The overall allochemical similarity and close association suggest convincingly that the Algal Branch Packstone are in part eroded and transported material from the Rhodolith Pavement facies. | |
