The Kapp Toscana Group is a geologic group in Svalbard and Jan Mayen in the Barents Sea, Norway.[1]

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 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, while its two members Tschermakfjellet and De Geerdalen had type sections from Botneheia.[7]
