Description

The group dates back to the Late Triassic, and comprises the rock formations of Tschermakfjellet, De Geerdalen and Wilhelmøya.[2] The group is named from the headland of Kapp Toscana at the southern side of Van Keulenfjorden in Wedel Jarlsberg Land at Spitsbergen, Svalbard.[3] The thickness of the group varies from 8–500 metres (26–1,640 ft) of deltaic shales with interbedded sandstones.[4]

The Kapp Toscana Group was initially defined as a formation,[5] but has later become a group.[6] The type section was taken from Kapp Toscana at Van Keulenfjorden, where the thickness of the unit was 200 metres (660 ft), while its two members Tschermakfjellet and De Geerdalen had type sections from Botneheia.[7]

gollark: No, I mean you said you would ignore metadiscussion outside it.
gollark: You could express opinions and discuss things *anyway*, see.
gollark: It's a slightly different discussion channel with more constraints. It isn't particularly amazing as an innovation, and it enforces a style of communication you prefer and some don't on pain of being ignored (more).
gollark: You are assuming that people actually all thought of it as a good thing in the same way.
gollark: I think this misrepresents things on various levels, but thing.
