Lithology and environment
| Primary lithology: | "limestone" | ||
| Environment: | open shallow subtidal | Tectonic setting: | cratonic basin |
| Geology comments: SEP: from Samtleben et al. (1996). Geol Rundsch 85:278; "In the central ara of Gotland..consists of narrowly spaced reefmounds consisting mainly of tabulates, sstromatopores and bryozoans within a shoal area with coarse and medium-grained biodetritic and crinoidal limestones, which have been extensively transported, washed and sorted. To the west the platform ends with a slope forming the transition to a deeper basin area where limestone-marl alterations were deposited. In the eastern part of Gotland...series of limestones (mainly wackestones and packstones), often oncolitic and with an impoverished fauna. They accumulated in shallow water under back reef to restricted marine conditions." This source gives no indication of where in this facies complex the samples were taken. I have made an informed probabilistic estimate of the environment based on the area of outcrop of each facies as shown on pages 279-280. | |||
