| 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; "....series of argillaceous and micritic limestones and marls with a diverse marine fauna but impoverished conodont assemblage deposited in a shelf basin under calm conditions well below wave base." | |||
