| Environment: | open shallow subtidal | Tectonic setting: | cratonic basin |
| Geology comments: SEP: Silurian of Gotland has been variably described as a ramp and platform. Based on my read of the literature, I think if falls best into the ramp category. From Samtleben et al. (1996). Geol. Rundsch 85:278-292; "...this unit consists of a carbonate platform with reef mounds and surrounding shoal sediments of mostly pure biodetritic and pleoidal limestones. Here slow and discontinuous accumulation of carbonate material continued in a very shallow water but under normal marine conditions....to the south and southwest the carbonate platform passes with a conspicuous slope into a deeper shelf basin where a uniform alternation of micritic limestones and marls accumulated." Based on information provided in this collection, it is difficult to tell which facies is represented but I have assumed that it represents the more extensive shallow subtidal facies. | |||
