North Atlantic Neoproterozoic–Mesozoic tectonic linkages between the Appalachian, Caledonian, and circum-Arctic orogens
Session ID#: 82304
Session Description:
The Neoproterozoic–Mesozoic tectonic history of the North Atlantic region remains contentious. Topics of debate include the timing and history of Rodinia fragmentation, terrane transfer during the assembly of Baltica, Gondwana and Laurentia, closure of oceanic basins, and proposed kinematic links between various circum-Atlantic orogens (e.g., Appalachian, Caledonian, Ellesmerian, Timanian and Cordilleran). This process requires a firm understanding of major pre-Cenozoic tectonic boundaries in the North Atlantic region, as these structures clearly influence the recent evolution of the North Atlantic (see Session 82661). We aim to attract contributions covering a broad spectrum of disciplines including, but not limited to, geochronology, paleontology, petrology, sedimentology, stratigraphy, and structural geology. This interdisciplinary session will highlight results of recent work in the North Atlantic and elucidate new relationships to adjacent regions.
