The Meliaticum of the eastern Alps – sourced from the east, displaced to the west

The original site of deposition was a seaway extending at a high angle to the Neo-Tethys margin northwards between ALCAPA/Tisza and Dacia, connecting the Neo-Tethys Ocean with the evolving Piemont-Ligurian Ocean. During the Late Jurassic, when the Piemont-Ligurian Ocean (Alpine Tethys) widened and the Neo-Tethys closed, the Austroalpine Meliata units were displaced approximately 400 km westward along a transform fault system connecting both oceans and penetrating the thinned ALCAPA crust.</p> <p></p><p>Austroalpine Meliaticum is a mélange of deep-water sediments deposited adjacent to the Adriatic shelf.</p><p>The detrital U/Pb zircon data indicate provenance from multiple sources.

The sediments supplying the Meliata Basin were routed from Avalonia, Galatian / Ligerian ALCAPA, and South Carpathian Dacia/Serbo-Macedonia.</p><p>The Austrian Meliaticum was displaced from its original home 400 km westward during Jurassic strike-slip tectonics.</p><p></p> <p>Austroalpine Meliaticum is a mélange of deep-water sediments deposited adjacent to the Adriatic shelf.</p> <p>The detrital U/Pb zircon data indicate provenance from multiple sources.
