Model description: Digital outcrop model of Midterhuken, at the far end of the headland where Van Keulenfjorden and Van Mijenfjorden meet. It exhibits a natural transect of the Palaeogene fold-and-thrust belt along Spitsbergen’s west coast. The deformation involves two main geologic sequences. Basement rocks on Midterhuken’s western tip (Hecla Hoek sequence) were metamorphosed and penetratively deformed during the Caledonian orongeny, and were uplifted and tilted during Tertiary deformation. To the east is a Lower Carboniferous to Cretaceous plaatform cover sequence (2 km thick) of unmetamorphosed carbonate and clastic rocks; it unconformably overlies the Hecla Hoek rocks, and forms a northeast-dipping homocline with locally complex structures (Maher et al., 1984). The Gåshamna Fm, Treskelodden Fm, Orustdalen Fm, Wordiekammen Fm, Gipshuken Fm, Kapp Starostin Fm, Vardebukta Fm, Tvillingodden Fm, Bravaisberget Fm and Kapp Toscana Gr are successively exposed eastward. Data availability: All uploaded archives are to be extracted to the same directory for a functional working environment, i.e., at the very least consisting of a project folder with the data and metashape subdirectories. The included processing report specifies the processing parameters that were used as input for the processing software (Agisoft Metashape, v1.7.2.12040). Ground control point data use CRS epsg:4326. Exported model data use CRS epsg:32633. Show and visualise on Svalbox.no: Through Svalbox we aim to take geoscientific research and education to the next level – with the simple motto of placing all key information and data sets in their correct spatial position. We bring modern technology, in particular cost-effective digital outcrops, to complement more than 200 years of geoscientific research on Svalbard. Finally, Svalbox provides a sustainable platform for sharing results, workflows and teaching material with the wider geoscientific community.
