Descrizione:
The MongolOkhotsk Belt extends from the present Sea of Okhotsk in the northeast to Central Mongolia in the southwest and represents a part of the widespread Central Asian Orogenic Belt. The MongolOkhotsk suture zone was generated during the Late Paleozoic to Mid Mesozoic by the subduction of the MongolOkhotsk Ocean. The remnant permits to study the enigmatic tectonic evolution of the paleoocean. A suitable place for analyzing the geodynamic development of the MongolOkhotsk Ocean is given by the HangaiHentei basin in Mongolia that is regarded as an accretionary wedge terrane located northwest of the suture zone. This research yielded new data from lithostratigaphic and sedimentological investigations as well as provenance analyses on the Silurian to Carboniferous northern active continental margin of the MongolOkhotsk Ocean. The work is focused on the Carboniferous trench basin turbidite series of the Gorkhi Formation within the HangaiHentei basin. Field work and sample collection in the HangaiHentei basin provided new data for defining the type and timing of ocean formation, the subduction and the opposing margins.
