Well-preserved fossil reef/mound-building communities and shallow microfacies have been recovered from Changhsingian platform−margin sponge reef at the Panlongdong Section and intraplatform sponge skeletal mound at the Yanggudong Section in NE Sichuan Basin, South China. The present contribution focuses on the palaeoenvironmental implication of the differentiated development processes on the ...The mound capping facies include a lower skeletal packstone–wackestone and an upper lagoon facies marlstone and black shale. 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.Note its massive body and surrounding deposits of intraclastic-skeletal packstone to grainstone (P/Gi) and overlying facies of differentially compacted mudstone with dissolution seams (Md).

The lower and upper limestone submembers of the middle mixed lithology member mostly consist of subtidal carbonate facies with limestone–clastic mudstone couplets; lime mudstone to wackestone; skeletal and peloidal wackestone to packstone; and peloidal, skeletal, and intraclastic packstone to grainstone, with minor massive clastic mudstone ...Hasil analisa fasies yang ada pada daerah penelitian adalah terdapat 5 fasies,yaitu; Skeletal Debris Packstone – Wackestone, Coral Algal Grainstone - Boundstone,Skeletal Wackestone, Skeletal Packstone dan Coral Algal Packstone.
