Pulsed Miocene range growth in northeastern Tibet: Insights from Xunhua
Sedimentary rocks in Tibetan Plateau basins archive the spatiotemporal patterns of deformation, erosion, and associated climate change that resulted from Cenozoic continental collision. Despite growing understanding of basin development in northeastern Tibet during initial India-Asia collision, as well as in the late Miocene–Holocene, surprisingly little is known about the intervening period: a...
متن کاملMagnetostratigraphy of Oligocene - Miocene Glaciomarine Strata from CRP-2/2A, Victoria Land Basin, Antarctica
We have used palaeomagnetic methods to constrain an age model for the 624.15 m succession of Oligocene-Miocene glaciomarine sediments recovered from the CRP-2/2A drillcore, McMurdo Sound, Antarctica. Identification of characteristic remanent magnetization (ChRM) directions on vector component plots demonstrates that secondary overprints have been successfully removed by stepwise alternating fie...
متن کاملFlexural subsidence by 29 Ma on the NE edge of Tibet from the magnetostratigraphy of Linxia Basin, China
This study provides a detailed magnetostratigraphic record of subsidence in the Linxia Basin, documenting a 27 Myr long sedimentary record from the northeastern edge of the Tibetan Plateau. Deposition in the Linxia Basin began at V29 Ma and continued nearly uninterruptedly until V1.7 Ma. Increasing rates of subsidence between 29 and 6 Ma in the Linxia Basin suggest deposition in the foredeep po...
متن کاملConstraints on mountain building in the northeastern Tibet: Detrital zircon records from synorogenic deposits in the Yumen Basin
The Cenozoic basins and ranges form the high topography of the northeastern Tibet that resulted from the India-Eurasia collision. Sedimentary rocks in the basins provide direct insight into the exhumation history of the ranges and the tectonic processes that led to the northeastward growth of the Tibetan Plateau. In this study, we analyzed and compared detrital zircon U-Pb ages from sands of mo...
متن کاملLate Miocene northward propagation of the northeast Pamir thrust system, northwest China
Piggyback basins on the margins of growing orogens commonly serve as sensitive recorders of the onset of thrust deformation and changes in source areas. The Bieertuokuoyi piggyback basin, located in the hanging wall of the Pamir Frontal Thrust, provides an unambiguous record of the outward growth of the northeast Pamir margin in northwest China from the Miocene through the Quaternary. To recons...
