Middle-Late Jurassic sedimentary mélange formation related to ophiolite obduction in the Alpine-Carpathian-Dinaridic Mountain Range

摘要: Abstract The Middle-Late Jurassic mountain building process in the Western Tethyan realm was triggered by west- to northwestward-directed ophiolite obduction onto wider Adriatic shelf. This southeastern eastern shelf former passive continental margin of Neo-Tethys, which started open Middle Triassic. Its western parts closed from around Early/Middle boundary with onset east-dipping intra-oceanic subduction. Ongoing contraction led since Bajocian. Trench-like basins formed concomitantly within evolving thin-skinned orogen a lower plate situation. Deep-water sequence northwest-/westward propagating nappe fronts, served as source areas basin fills. Basin deposition characterized coarsening-upward cycles, i.e. sedimentary melanges synorogenic sediments. fills became sheared successively ongoing contractional tectonics features typical melanges. Analyses ancient Neo-Tethys along Eastern Mediterranean ranges allow both, facies reconstruction outer and conclusions on processes timing orogenesis. Comparison identical age component spectrum different belts figured out one Ocean realm, instead multi-ocean multi-continent scenarios.
