Abstract We reconstruct the rise of a segment southern flank Himalaya-Tibet orogen, to south Lhasa terrane, using paleoaltimeter based on paleoenthalpy encoded in fossil leaves from two new assemblages Tibet (Liuqu and Qiabulin) four previously known floras Himalaya foreland basin. U-Pb dating zircons constrains Liuqu flora latest Paleocene (ca. 56 Ma) Qiabulin earliest Miocene (21–19 Ma). The proto-Himalaya grew slowly against high (∼4 km) proto–Tibetan Plateau ∼1 km late ∼2.3 at beginning...
Mesozoic strata of the Hoh‐Xil‐Songpan‐Ganzi complex in northern Tibet are exposed a vast (> 370,000 km 2 ) triangle‐shaped orogenic belt bound by Longmen Shan thrust east, Kunlun terrane and North China block north, Qiangtang Yidun arc south. These consist Middle–Upper Triassic submarine fan deep marine facies rocks that were deposited Paleo‐Tethys Ocean. Late Triassic–Early Jurassic contractional deformation eastern marks demise Ocean basin accretion Gondwana‐derived to Eurasia. We...
The northernmost exposures of sub-Himalayan Cenozoic strata in the Hazara–Kashmir syntaxial region north Pakistan comprises Paleocene–Eocene marine lower part and Oligocene–Miocene nonmarine upper part. This study provides detrital zircon U–Pb geochronology this area. strong resemblance age spectra Paleocene Hangu, Lockhart Patala formations with those Himalayan indicate an Indian plate provenance. first appearance <100 Ma ages within most Early Eocene Margalla Hill Limestone indicates a...
Reconstructing the Paleogene topography and climate of central Tibet informs understanding collisional tectonic mechanisms their links to biodiversity. Radiometric dates volcanic/sedimentary rocks paleotemperatures based on clumped isotopes within ancient soil carbonate nodules from Lunpola Basin, part an east-west trending band basins in now at 4.7 km, suggest that basin rose <2.0 km 50 38 million years (Ma) >4.0 by 29 Ma. The height change is quantified using rates which wet-bulb...
Abstract The Mesozoic plate tectonic history of Gondwana-derived crustal blocks the Tibetan Plateau is hotly debated, but so far, paleomagnetic constraints quantifying their paleolatitude drift remain sparse. Here, we compile existing data published mainly in Chinese literature and provide a new, high-quality, well-dated pole from ca. 180 Ma Sangri Group volcanic rocks Lhasa terrane that yields 3.7°S ± 3.4°. This new confirms trend suggests drifted away Gondwana Late Triassic time, instead...
Views differ on the uplift history of SE Tibetan Plateau and causal geodynamic mechanisms, yet reliable age-constrained paleoaltimetry in this region could test growth models entire plateau. Here we apply carbonate clumped isotope thermometry to well-dated paleosols marls Gonjo Basin, Tibet, reveal topographic evolution basin. The sedimentary ages carbonates lower upper Ranmugou Formation are constrained 54-50 Ma 44-40 Ma, respectively. temperature derived from indicates mean annual air...
The uplift of eastern Tibet, Asian monsoon development and the evolution globally significant biodiversity are all linked, but in obscure ways. Sedimentology, geochronology, clumped isotope thermometry, fossil leaf-derived numerical climate data from Relu Basin, show at ∼50-45 Ma basin was a hot (mean annual air temperature, MAAT, ∼27 °C) dry desert low-elevation 0.6 ± km. Rapid rise to 2.0 0.9 km 45-42 2.9 42-40 Ma, with MAATs ∼20 ∼16 °C, respectively, accompanied seasonally varying...
The origin of the northern Qiangtang block and its Late Paleozoic–Early Mesozoic drift history remain controversial, largely because paleomagnetic constraints from pre-Mesozoic units are sparse poor quality. In this paper, we provide a robust well-dated pole Lower Permian Kaixinling Group lavas on block. This suggests that had paleolatitude 21.9±4.7°S at ca. 296.9±1.9Ma. These first volcanic-based results rocks appear to average secular variation accurately enough yield well-determined...
Southeastern (SE) Tibet forms the transition zone between high interior Tibetan Plateau and lowlands of southwest China. So understanding elevation history SE Tibet, a biodiversity 'hotspot', enlightens our interactions tectonics, monsoon dynamics biodiversity. Here we reconstruct uplift Markam Basin, during middle−late Eocene based on U − Pb dating, plant fossil assemblages, stable clumped isotope analyses. Our results suggest that floor Basin was at an 2.6 ± 0.9 km 42 Ma 39 Ma, where mean...
We describe a new method to estimate directly ductile strain rates at an outcrop scale from the deformation of dikes emplaced within shear zone. The is tested in well‐constrained zone: Ailao Shan–Red River zone, for which global can be calculated published fault rates. rate was determined by measuring independently ( γ ) recorded and age t emplacement. quantified three different methods that take into account either stretching or their angle variations during both them. values minimum...
Abstract The construction of Earth’s largest highland, the Tibetan Plateau, is generally considered to have been generated by Cenozoic India-Asia collision. However, extent which high topography existed prior remains unclear. Hexi Corridor foreland basin northern Plateau an ideal region in investigate this history, given its widespread exposure Early Cretaceous sedimentary sequences. In study, we examined strata understand relationships between pre-Cenozoic sedimentation and tectonic...
