dc.description.abstractThe Shandong Peninsula in the eastern North China Craton (NCC) forms part of the region that witnessed extensive tectonic reactivation with concomitant craton destruction and lithospheric thinning during the Meso-Cenozoic. Previous studies concentrated mainly on the timing, mechanism and tectonic setting of the Meso-Cenozoic magmatism, with inadequate evidence from low temperature thermochronology to constrain the thermo-tectonic exhumation history of this region. In this study, we present new apatite U-Pb (AUPb) and fission track (AFT) data with corresponding thermal history models for igneous rocks from the two flanks of the Tan-Lu Fault Zone (TLFZ) that bisects the Shandong Peninsula, with a view to gain insights into the Meso-Cenozoic exhumation history of this region and to evaluate its implications on the lithospheric destruction of the NCC. The newly obtained AUPb ages of 2.5-1.5 Ga for the Precambrian intrusive rocks and of 162-112 Ma for the Mesozoic igneous suite are mainly used to constrain their thermal history models. In addition, the Mesozoic AUPb ages of 162-112 Ma highly overlap with their corresponding zircon U-Pb ages (161-115 Ma), suggesting shallow granitoid emplacement and associated rapid post-magmatic cooling in response to the westward subduction of the Paleo-Pacific Plate. The AFT dating results yield two groups of AFT central ages at 122-113 Ma and 98-59 Ma, and corresponding thermal history models also reveal two rapid cooling stages during the Early Cretaceous (130-105 Ma) and Late Cretaceous to Paleogene (85-55 Ma). By integrating previous low temperature therrmx:hronological studies with this study, we interpret that the Early Cretaceous rapid exhumation corresponds to the peak timing of craton destruction, resulting from the Paleo-Pacific slab rollback within a back-arc extensional setting. The Late Cretaceous rapid exhumation is interpreted as a response to continuing craton destruction, derived by the NNW-directed Pacific Plate subduction.The Paleogene cooling might represent the termination of craton destruction of Shandong Peninsula associated with a dextral motion along the TLFZ, triggered by the change in direction of the Pacific Plate from NNW to WNW and/or far-field effect of the India-Eurasia collision.
