Anatexis is significant for the evolution and rheological properties of the continental crust， linking metamorphism， tectonic deformation， and magmatic activities in deep crust. According to the presence or absence of free water， anatexis can be divided into water-fluxed melting and dehydration melting. Dehydration melting involves the breakdown of hydrous phases， such as muscovite， biotite or amphibole. Generally， dehydration melting reactions begin at ~650 ℃ and produce melt， peritectic garnet and K-feldspar. Melt resulting from dehydration melting is water unsaturated， characterized by high Rb， high Rb/Sr ratio， high ⁸⁷Sr/ ⁸⁶Sr ratio， and low Sr， Ba， Ca. Melt productivity of dehydration melting reaction is controlled by P- T condition and water content in rock， and it is only possible to produce a large amount of melt at granulite facies. Water-fluxed melting reactions involve the presence of free water. Its most significant feature is that the temperature required is relatively low， and can produce voluminous melting at amphibolite facies. The resulting melt is water-saturated or water unsaturated that can extract from the source. Melt derived from water-fluxed melting reactions has high Sr， Ba， Ca， low Rb/Sr ratio and low Rb. Anatexis has a profound impact on the thermodynamic and rheological properties of the rocks. At the same time， the movement of melt out of the lower continental crust promotes the chemical differentiation of the crust and forms a wide range of leucogranite， playing a crucial role in the origin， reworking， and stability of the continental crust.

As the importance of hydrogen continues to grow, large-scale hydrogen storage is receiving increasing focus. In this paper it extensively examines the classification, advantages, and drawbacks of underground hydrogen storage facilities through comprehensive literature research, providing a theoretical foundation for the implementation of such storage systems. Furthermore, it elucidates the interactions between hydrogen and minerals, and highlights the hydrogen adsorption characteristics of clay minerals and coal seams, offering novel insights into addressing challenges related to large-scale hydrogen storage and low-cost adsorption-based storage. The study findings reveal that (1) hydrogen storage facilities are primarily categorized into salt cavern storage, depleted oil and gas reservoir storage, and aquifer storage, with salt cavern storage currently being the most favorable option; (2) variations in temperature, pressure, concentration of fatty acids, and organic acid carbon number affect the hydrogen wettability of minerals, thus impacting caprock sealing capacity; and (3) certain clay minerals, coal seams, and other materials can adsorb hydrogen, presenting potential avenues for new underground hydrogen storage materials. Based on the above research and analysis, the main problems existing in underground hydrogen storage are pointed out, and the future development prospect of underground hydrogen storage is prospected, in order to provide reference for the site selection and implementation of underground hydrogen storage. The feasibility of underground porous material as a new large-scale hydrogen storage material is briefly summarized, in order to contribute to the search for diversified and suitable hydrogen storage materials.

According to geochemical information analysis of Neoproterozoic igneous rocks in the periphery and interior of Sichuan basin, there are two completely different understandings of extension and extrusion. The geophysical data show that the deep rifting of the basin is widespread, and there are obvious uplift and denudation in the central and western parts of the basin until the deposition period of Doushantuo Formation. The tectonic transformation process between the two is unclear. To solve these problems, in this paper it explores the Neoproterozoic tectonic evolution and favorable oil and gas areas of the Sichuan basin through the interpretation of seismic reflection profiles and the analysis of petrogeochemistry, drilling data and outcrop sedimentary sequences. The results in this study show that the oceanic subduction was the cause of the rift-uplift denudation transformation in the western and central Sichuan during the period from the breakup of the Rodinia supercontinent to the convergence of the Gondwana supercontinent, while the eastern Sichuan area was always in tectonic subsidence in the middle and late Neoproterozoic (820-551 Ma).There may only be organic rocks of Wuye Formation at the same time in the Neoproterozoic of western Sichuan and central Sichuan, and clastic reservoirs are developed between the uplift area of central Sichuan and the subsidence area of eastern Sichuan.
