The data of major and trace elements were analysed by ICP-MS at the State Key Laboratory of Isotope Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. Zircon U-Pb ages and trace elements were analysed by LA-ICP-MS at the Key Laboratory of Mineralogy and Metallogeny of CAS, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. The international standard samples and reference values measured in the same batch are consistent within the error range, with low blank in the whole process. The samples of YMS and FS batholiths range from diorite to granite (52‒75 wt. % SiO2), and both show the higher bulk rock Fe3+/ΣFe ratios (between 0.3 and 0.6). The Fe3+/ΣFe of low silica (SiO2<65 wt. %) samples of Dabie are consistent with YMS and FS, but the high SiO2 samples show the low ratios (between 0.1 and 0.3) . Compared with MORB, all the samples show the high ƒO2.Majority of zircons Ce4+/Ce3+ and Eu/Eu* ratios are mostly in range of 100-1000, and consistent with ore-bearing porphyries in Chile and China (e.g., Dexing), indicating the high ƒO2. Conversely, the inherited zircon (~2.5 Ga) Ce4+/Ce3+ ratios of Liguo and FS plutons range from 10 to 200, similar to those of ore barren porphyries in Chile, i.e. low ƒO2 .That adakitic rocks with high oxygen fugacity are very widespread in the NCC. Those magmas were derived from partial melting of thickened lower continental crust with the mixing of mantle materials, and the high ƒO2 characteristic inherited from an oxidized mantle source that has been modified by fluids and/or melt derived from (Paleo)-Pacific plate.

Apatite (U-Th)/He data from the Nuomuhong region of the East Kunlun Shan. Apatite (U-Th)/He analysis was conducted at the State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration using the Australian Scientific Instruments (ASI) Alphachron noble gas mass spectrometer and Agilent 7900 inductively coupled plasma mass spectrometry. Reproducibility within each sample were reasonably good. We determine the paleodepth of each sample by measuring the distance perpendicularly from the erosion surface to the sample. All new and published ages are plotted against their paleodepth. The age-paleodepth relationship shows a break in slope at ~25 Ma, which is interpreted to initiation of thrusting at northern margin of the East Kunlun Shan.

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 data include: a brief introduction of the geodynamic evolution model of the formation of Cu Mo polymetallic granodiorite (porphyry) in Chizhou area. The changes of geological structure before and after 150mA in Chizhou area, as well as the changes of influence on metallogenic model, are shown in the figure. At 150 mA, Chizhou area was affected by the inversion of the paleo Pacific plate, forming an arc rift environment without marine sediments. The fluid released from the plate melted the mantle wedge material, produced a high oxygen fugacity environment, formed chlorine rich fluid and mixed mantle crust magma, promoted the extraction and migration of metals, and finally formed the copper molybdenum polymetallic deposit in Chizhou area. The above data have been published in SCI high-level journals, and the data are true and reliable. The data is stored in JPG format.

The contents include: plane model diagram of strata deformation and shear strain change after 10% compression of the model of Huangjindong deposit in northeastern Hunan Province; Plane model diagram of strata deformation and shear strain change after 2% extension of Huangjindong deposit model in Northeast Hunan Province; Plane model diagram of strata deformation and volume strain change after 2% stretching of Huangjindong deposit model in Northeast Hunan Province; The cross-section model map of strata deformation and shear strain change after 1% compression of Huangjindong deposit model in Northeast Hunan Province; Section model of strata deformation and volume strain change after 1% compression in Huangjindong deposit, Northeastern Hunan Province; The cross-section model map of strata deformation and shear strain change after 1% stretching of Huangjindong deposit model in Northeast Hunan Province; The profile model of strata deformation and volume strain change after 1% stretching of the Huangjindong deposit model in northeastern Hunan Province. There are seven Mesozoic tectonic thermal fluid numerical simulation maps in eastern China. The establishment process of plane and profile model: the top surface of the profile model is 3km underground, and the geometric model is 633m long, 20m wide and 512 M high. The lithology of the stratum in the model is sandstone and slate interbedding, and is cut through by a fault. The plane model is 15.3km wide and 12.5km high. The model consists of sandstone, siliceous slate and two kinds of quartz bearing slate with four faults. The stratum and rock mass in the study area are defined as elastic-plastic materials, and the corresponding simulation calculation is carried out based on the Mohr Coulomb strength criterion. The Mohr Coulomb strength criterion is adopted. The permeability and porosity of each geological unit are mainly based on the measured parameters of different geological units in Northeast Hunan, while the mechanical parameters are mainly from the FLAC3D manual or the test data of similar lithology. According to the previous research results and the actual geological characteristics of the mining area, the initial and boundary conditions of deformation and fluid flow are set, and the fluid flux is given to the whole model according to the mode and direction of fluid migration. In the initial state, the initial state of all pores in the rock is water saturation, that is, the saturation is 1. According to the theoretical model of ore-forming fluid pressure of hypabyssal rock, the initial pore pressure in the formation is set as hydrostatic pressure, and the pore pressure on the top surface of the model is fixed. The surface of the model is a permeable boundary, and other boundaries are set as impermeable boundaries. Then the initial geostress is balanced to get the equilibrium state. Then, the mechanical boundary conditions are set for the model. Combined with the characteristics of the ore deposits in northeastern Hunan formed in the tectonic environment of first compression and then tension, the two models are compared with each other, and the symmetrical initial compression velocity (2.425) is applied on the left and right boundaries of one model × 10-9 M / s) to simulate the process of tectonic compression, while the symmetrical initial tension velocity (2. 425 M / s) was applied to the left and right boundaries of the other model × 10-9m / s) to simulate the process of tectonic extension. Main conclusions and Enlightenment: the dynamic mechanism of the mineralization process of Huangjindong gold deposit is discussed through numerical simulation. Under the action of tectonic compression and tectonic extension, a large dilatation area appears in the slate near the fault. The formation of dilatation space can provide a favorable metallogenic space for mineral precipitation and metasomatism, and provide a favorable place for the convergence of ore-forming fluids, The simulation results show that the expansion location is basically corresponding to the known ore body. It also shows that the mineralization process of gold deposits in Northeast Hunan is closely related to mechanical action. At the same time, for other gold deposits or other types of gold deposits in Northeast Hunan, this simulation study also has a certain reference value, that is, through obtaining the relevant metallogenic geological characteristics (tectonic stress environment, rock mechanics parameters, etc.), studying the rock mass properties, strata deformation characteristics and the migration law of ore-forming fluid in the ore body location, It can clearly show the physical process of mineralization, improve the existing metallogenic model, and provide a theoretical basis for further prospecting. The above data have not been published yet. The results are expected to be published in SCI high-level journals, and the data are true and reliable. The data is stored in JPG format.

The data of major and trace elements were analysed by ICP-MS at the State Key Laboratory of Isotope Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. Zircon U-Pb ages and trace elements were analysed by LA-ICP-MS at the Key Laboratory of Mineralogy and Metallogeny of CAS, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. The international standard samples and reference values measured in the same batch are consistent within the error range, with low blank in the whole process. The data quality is accurate and reliable. The samples of Guandian pluton show high SiO2 (59.15-62.32%), Al2O3 (14.51-15.38%), Sr (892-1184 ppm), Sr/Y (57.63-86.32) and low Y (12.65-18.05 ppm), similar to typical geochemical features of adakite. The Guandian adakite also exhibits high K2O (2.88-3.86%), MgO (3.89-5.24%) and Mg# (55-60), negative anomalies of high field strength elements (HFSE, e.g., Nb, Ta and Ti) and positive anomalies of Ba, Pb and Sr. LA-ICP-MS zircon U-Pb dating yielded a weighted average age of 129.2 ± 0.7 Ma. Calculations of zircon Ce4+/Ce3+ (6.79-145) and (Eu/Eu*)N (0.23-0.42) on the basis of in situ zircon trace element analysis indicate that the magma had a lower oxygen fugacity relative to the ore-bearing adakites in the LYRB and Dexing, which is consistent with the fact of ore-barren in the research area. In combination with previous research, we propose that Guandian adakite was formed by partial melting of delaminated lower continental crust triggered by Early Cretaceous ridge subduction of the Pacific and Izanagi plates.
