Skeletal packstone
The shoal is composed of skeletal and oolitic grainstone and mud-lean packstone, and some storm-derived stromatoporoid- and coral fragments. Stromatoporoid-coral biostromes and bioherms characterize the proximal middle ramp where, in the inter- and back-mound sheltered areas Cladocoropsis occurred in banks.Representative photographs of massive skeletal packstone (F7). (A) Core photograph of F7 showing the massive structure, FY 10, 2790.57 m. (B) Enlarged area of box in (A) suggests F7 mainly comprises benthic robust mollusc skeletal fragments. Most of these skeletal grains are highly broken and exhibit high angle to horizontal bedding.Basinal wackestone Skeletal grainstone Lagoonal Packstone Wackestone-Packstone Facies code 1 km (~3,300 ft) 0 ft) Well trajectory Cuttings sample positions Depositional model in cross section

Various algal colonies performed different roles in the formation of the mound. Komia colonies were the mound constructors that baffled higher energy currents and entrapped fine sediment.
