The Supanberget area – basement imbrication and detached foreland thrusting in the Tertiary fold-and-thrust belt, Svalbard
The Supanberget area, situated in the southern part of the Tertiary Spitsbergen fold-and-thrust belt, occupies a position mainly within the central zone of the belt, characterized by basement-involved thrusting, but includes part of an eastern foreland zone of detached, thin-skinned thrust tectonics...

The peculiar feature of Supanberget is the thrust- ‘sliced’ tectonic style that deforms a previously tightly folded basement-cover contact. Foreland structures indicate the additional presence of a subsurface detachment at a deeper structural level. Contrasts in magnitude and orientation of basement anisotropics may control lateral changes in tectonic style. |
