Taebaeksan Basin. Sung Kwun Chough, in Geology and Sedimentology of the Korean Peninsula, 2013. 5.2.12 Duwibong Formation. The Duwibong Formation comprises massive packstone to grainstone, flaser wackestone to packstone, bioturbated wackestone to grainstone, oncoid/ooid grainstone, limestone–shale couplet, and dark gray massive dolostone (Table 5.3; Figure 5.11R and 5.24B). Locally, the limestone is a packstone that consists, almost exclusively, of algae and smaller encrusting forams. In the northern part of the study area, in Hitchcock County, Nebraska, and locally over Cahoj Field, thin packstone and grainstone beds composed of mixed, fragmented skeletal grains are included in this lower interval.Based on lithology and stratal patterns, four facies groups have been recognized: (1) a flat-topped platform, in which thick algal boundstone, skeletal packstone–grainstone and peloidal micrite wackestone with a poorly rhythmic character prevail; (2) the platform margin and upper slope, characterized by microbial boundstone spanning a ... ….

In the Lower Cambrian of southwest Sardinia, a carbonate platform developed, showing clearly different stages of evolution: (1) a homoclinal ramp containing algal-archaeocyathan mounds (consisting mainly of Epiphyton and Renalcis boundstone) in the west, clastic tidal flats in the east; (2) an ooid-pellet barrier ramp with ooid-shoals, prograding toward the west. best tattoo shops in salem maa woman with a sense of humor The skeletal packstone-grainstone identified in the lower part of the succession formed in a high-energy normal marine subtidal environment. The middle part of the interval is characterized by skeletal intraclastic packstone-grainstone with rudists, foraminifers, rivulariacean cyanobacteria, gastropods and ostracods. sks handh archl This facies consisted of bivalve wackestone-packstone, gastropod wackestone, bivalve-gastropods packstone, gastropod and red algal packstones.
