Important scientific research results of the year
The oil and gas investigation in the Qaidam Basin has opened up a new field of Carboniferous exploration. The distribution range and residual thickness of the Carboniferous System in the Qaidam Basin were clarified, and it was found that the Carboniferous System is commonly developed under the Mesozoic and Cenozoic in the Qaidam Basin; the Carboniferous System in the Qaidam Basin was divided and compared, and the upper Devonian-Carboniferous system of the basin was compiled. Lithofacies paleogeography map of different stages; it is confirmed that the Carboniferous source rocks in the Qaidam Basin are well developed and have good oil-generating capabilities. A large number of Carboniferous oil and gas displays have been found, and the oil source comparison confirms that they are derived from Carboniferous source rocks. ; Research shows that Carboniferous structural deformation in the Qaidam Basin mainly occurred at the end of the Neogene, which is conducive to Carboniferous accumulation; at the same time, through reprocessing of seismic data in the Qaidam Basin, 10 Carboniferous traps were initially identified.
New results have been obtained in the study of the Cretaceous tectonic evolution process and dynamics of the South China continent. Through comprehensive analysis of basin sedimentation, structural deformation and magma evolution data, the Cretaceous geotectonic evolution process of South China was sorted out, and a three-stage alternating evolution model of extension and compression was proposed for the first time. The compression in the early Early Cretaceous (145-137 Ma) resulted in the general thickening and remelting of the continental crust, forming large-scale adakite, gneissic granite and migmatite, which were closely related to the ancient Pacific plate and the northern mid-ocean ridge. Low-angle subduction is closely related. In the Early to Middle Cretaceous (136-80 Ma), South China was in the geotectonic background of back-arc expansion. Regional sedimentation-magma-deformation evolution was related to the subduction of the ancient Pacific plate. The episodic alternation of extension-compression events reflected the arc's Complex subducting slab dynamics during post-extensional processes. In the Late Cretaceous (80-65 Ma), the dynamics of the peripheral plates underwent major adjustments, and the subduction of the Neo-Tethys tectonic domain controlled a new round of crustal extensional rifting and sedimentation-tectonic evolution.

Research on the "nature of the multi-stage rift events in the Mesozoic-Neoproterozoic of the North China Craton and their mineralization specificity" has made important progress. It was found that the zircon U-Pb age of the metamorphic volcanic rocks of the Zhaertai Group in the Langshan area is (804.1±3.5) Ma. Combined with the zircon U-Pb age of the metamorphic volcanic rocks of the Zhaertai Group in Langshan published by previous researchers (805.0±5.0) Ma According to the Pb age results, it is believed that the main age of the Zhaertai Group in the Langshan area is Neoproterozoic, ranging from about 800 to 1100 Ma. The zircon dating results of the Zaertai Group in the Zaertai Mountain area show that the age of the Zaertai Group is the Mesoproterozoic. The Zaertai Group in the Langshan area is different from the Zaertai Group in the east side of the Zaertai Mountains, as well as the Bayan Obo Group and the Huade Group. It is a set of Neoproterozoic valley sedimentary assemblages. It is recommended to restore the name of Langshan Group to refer specifically to this set of Neoproterozoic strata distributed in the Langshan area. The identification of the Neoproterozoic Langshan Group in the Langshan area of ??Inner Mongolia, on the one hand, fills the gap in the Neoproterozoic stratigraphy of the North China Craton; on the other hand, the Langshan-Zaltaishan-Bayon Obo Mesoproterozoic metallogenic belt identified by previous researchers is actually It should be disintegrated into two metallogenic belts of the Mesoproterozoic and Neoproterozoic. The mineralization age of the large submarine volcanic eruption deposits developed in the Langshan Group should be after the Neoproterozoic.

The "Comprehensive Study on the Determination of Important Active Faults and Active Tectonic Systems on the Southeastern Margin of the Qinghai-Tibet Plateau" has achieved fruitful results. Through detailed interpretation and investigation of active faults, coseismic surface rupture mapping and paleoseismic research, the distribution and composition of the main active faults in the area, their activity, and the characteristics of historical earthquakes and paleoseismic activities were identified, and a comprehensive understanding of the area was obtained. High-precision surface rupture distribution image. Research shows that the Yushu active fault zone constitutes the tail end structure of the Yushu-Xianshuihe-Xiaojiang fault system and is a typical "Z"-shaped left-lateral shear-tensional deformation zone. The left-lateral strike-slip rate during the late Quaternary can be It reaches 4.0~5.4mm/a, which regulates most of the block extrusion and rotational deformation in the area. It is the fault with the most significant seismic activity in the area. Paleoseismic research reveals that the in-situ repetition intervals of large earthquakes in the Yushu main strike-slip fault zone during the Holocene are obviously uneven, with an average of more than a thousand years and a maximum length of nearly 3000 years. Based on the newly discovered paleoseismic activity patterns, it is comprehensively judged that there are still at least 6 seismic gaps with different degrees of major earthquake risk on the Yushu fault zone in this area, and the estimated potential major earthquake magnitudes range from Mw 6.6 to 7.3.
