“…Additional magnetostratigraphic dating in the southwestern depression of Tarim Basin confirms the chronostratigraphic division of these formations. By integrating the fossil assemblages, magnetostratigraphic dating, and detrital igneous zircon chronology (Cao et al 2014), the age uncertainty at the boundaries of each two formations should be within 1 Myr. The age uncertainties of events are within 0.5 to 1 Myr at different stratigraphic levels based on calculated results assuming the accumulation rate within each formation is invariable.…”

“…This indicates the upper part of the Keziluoyi Formation could have been deposited between ~20-16 Ma and the top of the Anjuan Formation roughly at 14 ± 0.5 Ma, which is in line with the result of correlated ostracods among the Tarim Basin, Junggar Basin, and Kuche Depression (Jiang et al 1995). A minimal U/Pb age of 18.3 ± 0.5 Ma for detrital zircon chronology from a sandstone bed at the base of the Anjuan Formation (Cao et al 2014) could point to a 17 ± 1 Ma age for the sampled layer considering that the time needed for zircon exhumation and transportation (Malusà et al 2009). With this respect, the boundary of the Keziluoyi and Anjuan Formations in the Qimugan section could be assigned to be 18 ± 1 Ma based on the accumulation rate in the Anjuan Formation, which is in line with the biostratigraphic estimates.…”

“…The Materials and methods of previous whole-rock mineralogical, clay mineralogical, and geochemical data are given in Wang et al (2013a) and Cao et al (2014). For parts of the minor elemental data, the same samples of the Qimugan section in the Tarim Basin were analyzed, and the reported stratigraphic levels follow those of Wang et al (2013a).…”

“…From the same succession, Cao et al (2014) added whole-rock major elemental analysis to address paleoclimate and tectonic changes in the Tarim Basin in the Miocene. Here, we carefully review the age control on this succession based on detailed regional correlations of fossil ostracods and foraminifers across the Tarim Basin as well as to adjacent basins, with new magnetostratigraphic age data and detrital zircon chronology as age constraints.…”

Provenance change of sediment input in the northeastern foreland of Pamir related to collision of the Indian Plate with the Kohistan-Ladakh arc at around 47 Ma

et al. 2016

The Pamir plateau forms a prominent tectonic salient that marks the western end of the Himalayan orogen containing several terranes that were accreted to Eurasia from the Late Paleozoic to Cenozoic. A detailed knowledge of the tectonic evolution of the Pamir salient during the Cenozoic is important for our understanding of the intracontinental deformation in the western Himalaya. Although the tectonic evolution of the Pamir salient has long been studied, the timing of collision between the Indian Plate and the Kohistan-Ladakh arc is still a matter of debate. We present new U-Pb ages and Hf isotopes of detrital zircons, magnetic fabrics, and stable isotopes from the foreland basin on the northeastern margin of the Pamir that indicate a change in sediment provenance started at about 47 Ma. Sediments in the southwest Tarim Basin were partially derived from the uplifted and eroded Karakoram and Kohistan terranes created by the collision between the Indian Plate and the Kohistan-Ladakh arc at circa 47 Ma, as a result of northward thrusting and propagation of the Indian Plate under Eurasia.

Indentation of the Pamirs with respect to the northern margin of Tibet: Constraints from the Tarim basin sedimentary record

et al. 2016

The Pamirs represent the indented westward continuation of the northern margin of the Tibetan Plateau, dividing the Tarim and Tajik basins. Their evolution may be a key factor influencing aridification of the Asian interior, yet the tectonics of the Pamir Salient are poorly understood. We present a provenance study of the Aertashi section, a Paleogene to late Neogene clastic succession deposited in the Tarim basin to the north of the NW margin of Tibet (the West Kunlun) and to the east of the Pamirs. Our detrital zircon U‐Pb ages coupled with zircon fission track, bulk rock Sm‐Nd, and petrography data document changes in contributing source terranes during the Oligocene to Miocene, which can be correlated to regional tectonics. We propose a model for the evolution of the Pamir and West Kunlun (WKL), in which the WKL formed topography since at least ~200 Ma. By ~25 Ma, movement along the Pamir‐bounding faults such as the Kashgar‐Yecheng Transfer System had commenced, marking the onset of Pamir indentation into the Tarim‐Tajik basin. This is coincident with basinward expansion of the northern WKL margin, which changed the palaeodrainage pattern within the Kunlun, progressively cutting off the more southerly WKL sources from the Tarim basin. An abrupt change in the provenance and facies of sediments at Aertashi has a maximum age of 14 Ma; this change records when the Pamir indenter had propagated sufficiently far north that the North Pamir was now located proximal to the Aertashi region.
