Objectives: The Qiangtang Basin is the largest Mesozoic marine basin in the Xizang( Tibetan) Plateau. There have been a lot of debate about the nature and evolution of the Late Triassic Qiangtang Basin. The Zangxiahe Formation that deposited on the northern of the Qiangtang Basin and consist of sandstone and mudstone sediments,which is an significant record for the Late Triassic property of the Qiangtang Basin. The aims of this study are to constrain the nature and tectonic evolution of the Late Triassic Qiangtang Basin based on their provenance and tectonic setting of the Zangxiahe Formation sandstones.Methods: The X-ray fluorescence( XRF) and high-resolution inductively coupled plasma mass( HR-ICP-MS)are used to make the major and trace elements analysis of the Upper Triassic Zangxiahe Formation sandstones in Ganggairi area,the northern Qiangtang Basin. The major and trace elements analysis of samples were measured in the Analytical Laboratory,Beijing Research Institute of Uranium Geology,China.Results: For the Zangxiahe Formation sandstones,Si O2( 66. 9% ～ 76. 2%) and Al2O3( 10. 6% ～ 13. 2%) are the most abundant oxides. The second most abundant oxides are Fe2O3( 2. 70% ～ 4. 87%),Mg O( 0. 81% ～2. 25%),Ca O( 0. 42% ～ 3. 66%),Na2O( 1. 69% ～ 2. 36%) and K2O( 1. 63% ～ 2. 21%),while other oxides including Mn O,Ti O2 and P2O5 contents are lower than 1. 0%. Elements Si and P show slightly enrichment and other oxides show apparent depletion compared to UCC. In comparison with UCC,large-ion lithophile elements,include Sr,Cs and Ba,are depleted significantly. High field strength elements Zr and Hf have similar geochemical properties and enriched significantly. Transition trace elements,Sc,V,Cr,Co,Ni and Zn,also show apparent depletion. The total rare earth element( ∑REE) contents of the Zangxiahe Formation sandstones are 170. 3×10-6～253. 2×10-6( avg. 199. 4×10-6),which are higher than that of the UCC and have significant negative Eu anomaly.Conclusion: The CIA( 55. 0 ～ 65. 9,average 59. 1),CIW( 60. 6 ～ 74. 3,average 65. 9) and PIA( 56. 1 ～70. 6,average 61. 5) values indicate that the intensities of weathering in the source area were weak. No obvious Kmetasomatism occurred in these sandstones based on the A—CN—K diagram and low K2O contents. The relatively high ICV values reflect the source was first-cycle sediments of the active tectonic zone possibly. The Al2O3/Ti O2( 15. 4～21. 6,avg. 18. 5) values of the Zangxiahe Formation are similar to the intermediate igneous rocks,while Ti O2/Zr( 11. 9 ～ 33. 5,avg. 20. 3) values are similar to felsic igneous rocks. The Cr/Th—Sc/Th and Co/Th—La/Sc bivariate diagrams and significant negative Eu anomaly reveal that the Zangxiahe Formation sandstones were potentially derived from felsic igneous rocks,and mixed with minor intermediate igneous rocks. The( Fe2O3 T+Mg O) —Al2O3/Si O2,( Fe2O3 T+ Mg O) —Ti O2,( Fe2O3 T+ Mg O) —Al2O3/( Ca O + Na2O),Si O2—K2O/Na2O and La/Sc—Ti/Zr bivariate diagrams and La—Th—Sc,Th—Co—Zr/10,Th—Sc—Zr/10 triangular diagrams indicate that the source areas of the Zangxiahe Formation sandstones were sourced from the active continental margin and continental island arc,while also mixed with minor passive continental margin,which may be formed in the backarc foreland basin.

The late Mesozoic Magmatic arc of the South Qiangtang terrane is related to the long-term subduction of Bangong Lake Nujiang Tethys ocean and the subsequent collision of Lhasa Qiangtang terrane. However, the geological evolution from oceanic lithosphere subduction to continental collision is not clear. In view of this scientific problem, through the study of volcanic rocks in mudijiangya area of South Qiangtang terrane, the following achievements and understandings have been obtained（ 1) Zircon U-Pb dating data of two groups of volcanic rocks in mudijiangya area, Shuanghu County, central Qinghai Tibet Plateau show that the volcanic rocks of qushenla formation were formed at 114 Ma and those of abushan formation were formed at 76-75 ma（ 2) The original magma of the volcanic rocks in the qushenla formation may be derived from partial melting of mantle peridotite contaminated by crustal materials, which is related to the plate rotation of the northward subducted Bangong Nujiang Tethys oceanic crust（ 3) The original magma of volcanic rocks in the abushan formation may be a mixture of crustal melt and asthenospheric mantle, which is related to the lithospheric delamination in the Lhasa Qiangtang collision area.

The subsidence and exhumation histories of the Qiangtang Basin and their contributions to the early evolution of the Tibetan plateau are vigorously debated. This paper reconstructs the subsidence history of the Mesozoic Qiangtang Basin with eleven selected composite stratigraphic sections and constrains the first stage of cooling using apatite fission track data. Facies analysis, biostratigraphy, paleo-environment interpretation, and paleo-water depth estimation are integrated to create eleven composite sections through the basin. Backstripped subsidence calculations combined with previous work on sediment provenance and timing of deformation, show that the evolution of the Mesozoic Qiangtang Basin can be divided into two stages. From Late Triassic to Early Jurassic times, the North Qiangtang was a retro-foreland basin. In contrast, the South Qiangtang was a collisional foreland basin. During Middle Jurassic to Early Cretaceous times, thrust belt loading from the Jinsha River suture drove development of the combined retro-foreland basin. Detrital apatite fission track ages concentrate in late Early to Late Cretaceous (120.9-84.1 Ma) and Paleogene-Eocene (65.4-40.1 Ma). Thermal history modelling results record Early Cretaceous rapid cooling; the termination of subsidence and onset of exhumation of the Mesozoic Qiangtang Basin suggest that the accumulation of crustal thickening in central Tibet probably initiated during Late Jurassic-Early Jurassic (150-130 Ma), involving underthrusting of both the Lhasa and Songpan-Ganze terranes beneath the Qiangtang terrane, or the collision of Amdo terrane.

The Qiangtang terrane preserves an important record of the growth of the Tibetan Plateau since the Mesozoic; however, its deformation and cooling history remain poorly understood. To unravel this issue, we conducted geological mapping in the Esima area and detrital apatite fission-track and (U–Th)/He analyses of the Esima–Rongtang region in the east segment of Central Qiangtang terrane. Our results indicate that the east segment underwent two stages of structural deformation and rapid cooling during 120–110 Ma and 55–38 Ma. By combining our results with those of previous studies of the deformation and cooling history in the west segment, we reconstructed the early spatial and temporal geological evolution of the Central Qiangtang terrane since the Late Jurassic–Early Cretaceous. The structural deformation and cooling of the west segment at 150–130 Ma was related to northward flat subduction of the Bangong–Nujiang oceanic slab. The structural deformation and cooling of the east segment at 120–110 Ma and the west segment at 110–70 Ma was controlled by oblique convergence between Lhasa and Qiangtang. The structural deformation and cooling of the west and east segments at 55–38 Ma was associated with northward intracontinental subduction beneath the Qiangtang terrane induced by the Indo–Asian collision.

The collision of Lhasa Qiangtang terrane and its subsequent tectonic evolution are considered to be the most important event in the Tibetan Plateau before the Cenozoic India Asia collision. In view of this scientific problem, through the study of the late Cretaceous granite in Anduo area of Qiangtang terrane, the following achievements and understandings have been obtained. Zircon U-Pb geochronology, major and trace geochemistry and Sr Nd isotopic analysis have been carried out for the chuburi granite. The zircon U-Pb results of the two samples show that they were formed at 73-74 ma. The geochemical data show that the magmatic rocks have high contents of SiO2, K2O, Na2O, Al2O3 and total alkali, belonging to the high-k calc alkaline granite series. The normalized REE map of chondrite and the normalized trace element map of primitive mantle show that the magmatic rocks are characterized by enrichment of LREE and hree, enrichment of large ion lithophile elements and depletion of high field strength elements. Based on the analysis of petrological, petrographic and geochemical data, combined with the regional geological data, it is considered that the chuburi magmatic rock was formed by different degrees of mixed melt of mantle derived magma and lower crust derived melt, and then experienced the obvious separation and crystallization process of potash feldspar, plagioclase and other minerals. The formation of chuburi magmatic rocks is related to the delamination of lithosphere after the collision of Lhasa Qiangtang terrane
