Lithology and environment
| Primary lithology: | shelly/skeletal "limestone" | ||
| Includes fossils? | Y | ||
| Environment: | reef, buildup or bioherm | Tectonic setting: | cratonic basin |
| Geology comments: This formation consists of a number of isolated fossiliferous carbonate lenses, which have been referred to previously as organic reefs. Recent studies (Jaanusson in Ross et al., 1975, and Jaanusson, 1979) have shown, however, that no organic control or frame during the growth of these lenses can be recognized, and for this reason the term "car- bonate mounds" is deemed more suitable." | |||
