Abstract: An MS 7.4 earthquake occurred in Maduo County, Guoluo Tibetan Prefecture, Qinghai Province at 02:04 on May 22, 2021(Beijing time), which is the largest one in China after the 2008 Wenchuan MS 8.0 earthquake. Finding out the distribution and characteristics of its coseismic surface rupture in time is...
Abstract: The Midu area is located at the southeast end of the northwestern Yunnan fault depression zone, the intersection of the Red River fault zone and the Chenghai fault. It is a key area for uncovering the formation mechanism of the Northwest Yunnan fault depression zone as well as its kinematic relation...
Abstract: The southeast of the Anza Basin in Kenya, located in the East African Rift System, has developed a very thick Mesozoic and Cenozoic sedimentary cover. However, the low level of exploration in this area restricts us from understanding its structural system and evaluating its oil-gas exploration poten...
Abstract: Nowadays artificial seismic exploration is recognized as one of the most effective means to detect hidden faults in urban areas. However, good seismic exploration data in highly urbanized areas is often unavailable limited by the excitation source and strong interference. In this paper, a seismic de...
Abstract: Digital elevation model (DEM) is used to realize the digital simulation of terrain surface (i.e. the digital representation of terrain surface shape) through the limited terrain elevation data. As a new tool to describe the terrain, it provides a new field of vision for people to study the evolution...
Abstract: Oil-gas exploration in the Yinggehai basin shows, the formation, distribution and preservation of oil and gas resources are closely related to the overpressure system in the diapir zone. We based our analysis of the characteristics of generation, migration and reservior-forming of oil and gas resour...
Abstract: Basin modeling is an essential technical method for the exploration and assessment of petroleum basins. However, traditional 2D basin modeling technologies only apply to extensional basins. This makes the thermal history reconstruction in lateral direction of compressional basins an unsolved problem...
Abstract: The Pujue manganese deposit is a typical Datangpo-type sedimentary deposit of Nanhua period in eastern Guizhou. In the Pujue mining area the early-formed sedimentary manganese deposits were significantly influenced by the subsequent structures in aspects of burial and preservation. Analyzing the dee...
Abstract: Shanghai is located in the alluvial plain of the Yangtze River Delta, the merge area of the Huangpu River and Suzhou River. The unique geographical and sedimentary environment have formed the shallow sand layers in Shanghai. Due to the significant urbanization process in Shanghai, geological hazard ...
Abstract: This paper aims to ascertain the depositional paleoenvironment since the late Quaternary in the central Hebei plain. We measured the 20.74 m-deep Xibozhang section and analyzed the collected samples for grain size and optically stimulated luminescence (OSL) tests. OSL dating results indicate that th...
Abstract: The Yichang area located at the exit of the Three Gorges is covered with a set of thick Quaternary gravel layers, recording the evolution of the paleoenvironment and the formation of the Yangtze River. However, there has been a great dispute over the time when the Yangtze River materials in the uppe...
Abstract: Jinzhong Basin is a Cenozoic intracontinental faulted sedimentary basin located in the middle of Fen-Wei graben system. Our study aims to identify the Quaternary sedimentary sequence and reveal the Quaternary sedimentary environmental evolution of the Jinzhong Basin. We used structural petrography t...
Abstract: The precise age of the strata at the northeastern margin of the Tibetan Plateau in the Paleogene-Neogene, and the initial time when the uplift of the Plateau affected its northeastern margin, have always been two main bone contentions among geologists. The Guanyindian section at the northeastern mar...
