Abstract: Based on the 3D seismic data, through structural section interpretation, fault throw calculation, structural evolution analysis of balanced section and classification of transfer zone types, the formation mechanism of the Baodi-Tongbaizhen transfer zone in the Jizhong Depression is studied in this a...
Abstract: Faults in the Gulong oilfield are extremely developed. The fault sealing ability plays an important role in controlling the oil and gas migration and accumulation in the study area, so the study of fault sealing is in favor of the prediction of favorable locations for oil and gas accumulation. Quali...
Abstract: Evaluating measured in-situ stress state changes associated with large earthquake events plays a crucial role in earthquake prediction using measured in-situ stress data, whereas typical examples were not stated systematically yet. In this study, the Qiaoqi and Yingxiu regions which contain measured...
Abstract: The XujiaweiziFault Depression is located in the north of the Songliao basin, and its deep Mesozoic Huoshiling formation is a dense volcanic gas reservoir with natural fracture development and strong heterogeneity of the stress distribution. The present ground stress orientation of single well is an...
Abstract: Geomaterials are easily subject to tensile cracking. To model effectively deformation-cracking processes of geomaterials, a continuum-discontinuum method is developed, which is a combination of the Lagrangian element method and the fictitious crack method. This method can be used to more accurately ...
Abstract: The rare earth elements (REEs) in granodiorite porphyry and zircon from the Gaerqin copper deposit of Tibet, China, were geochemically traced, and the mineralization was also studied. The total levels of REEs in granodiorite porphyry varied slightly (ΣREE=48.64×10-6~78.12×10-6) with LREE/HREE=8.67~1...
Abstract: To solve the key problems to prospecting breakthrough, on the basis of the theory of prospecting prediction in exploration area, by conducting works such as structural-alteration special mapping, typical deposits analysis, the ore-forming geological bodies, the metallogenic structures, the metalloge...
Abstract: The south slope zone of the Laizhouwan Sag in the late stage has been reformed in many large-scale tectonic movements, resulting in the unclear appearance of the original basin and the unclear distribution of the sedimentary system. Based on the tectonic evolution analysis as the main line, through ...
Abstract: The paleo-uplifts in the Qaidam Basin are widely distributed and have great exploration potential. In order to indicate the exploration direction of the Qaidam Basin, the structural styles, sedimentary characteristics, evolution stages, kinematic characteristics and reservoir-forming laws of the mai...
Abstract: The channels developed in the Micocene Carbonera formation in the eastern part of the Llanos basin, Columbia, are so favorable reservoir that the accurate descriptions for these channels are key issues in this area. Guided by the simulation of wave equation, the seismic identification mode for chann...
Abstract: Major rockslide is the main type of geological hazards in the mining mountainous areas of southwestern China. The failure modes and behaviors of this kind of rockslides are complex. Taking the Jiguanling landslide as an example, centrifuge modelling was taken to analyze the failure mechanism of a st...
Abstract: The Huailai section of Beijing-Zhangjiakou (BZ) high-speed railway is located in the compound position of the Huaizhuo basin and Yanfan basin. The ground subsidence resulted from the difference of engineering geological characteristics of soil and sliding of buried faults in the basin will undoubted...
Abstract: A large number of unknown goaf areas formed in the random mining area of coal mine area, which are the causes of geological disasters such as ground collapse and ground fissure. In coal mining areas, underground caves are mainly coal mine goaf areas, showing the condition of being filled and not fil...
Abstract: Taking the Diangou shallow landslide in Qin-Ba Mountain Area as an example, deformation destruction characteristics and internal dynamic geological genesis are analyzed in detail and multi-scale through regional macrostructure, side slope microstructure and rock microstructure. The study results sho...
Abstract: Lattice anchoring is one of the frequently used prevention technologies for slope and landslide engineering. A large-scale physical model test was adopted to explore the interaction of actual mechanics characteristics of lattice frame anchorage in the detritus soil slope. Using the compacted clay fi...
