英文摘要: Located along the coast of Norway, the Trøndelag Platform area corresponds to the proximal domain of the Mid Norwegian Vøring rifted margin. We investigated its architecture and structural evolution based on interpretation of a dense network of high-resolution seismic reflection profiles, supplemented by comparison with local onshore analogues. The entire area is floored by ductile crustal shearing and regional-scale core complexes that form a corrugated surface with basement culminations that are flanked and sometimes cut by detachment faults. The detachments are segmented, suggesting long-lived and multiphase tectonic activity. The observed geometries are directly comparable to the ones mapped onshore in and around Devonian ‘Old Red Sandstone’ basins in western and south-western Norway, and in the adjacent North Sea. The combination of intensively sheared basement, core complexes, flanking and cutting detachment faults is interpreted to represent the offshore record of the transition from orogenic collapse to the first phases of rifting. The observations demand a revision of our conceptual approach of margins' proximal domains geometries for rifted margins that develop on collapsed orogens. © 2020 Elsevier B.V.
