In order to study its dynamic genetic mechanism. This fracture is studied by physical simulation, and two kinds of soft and hard materials are used for different basement control the simulation of fracture activity by displacement. Observing the evolution process and mechanism of the simulated geological structure, and comparing the different simulation processes and results through image records, establish a reasonable structural interpretation model. The experimental process reproduces the formation mechanism of conjugate faults in time and space, reveals that the central strike-slip conjugate fault zone in northeastern Shabei is formed by the intersection shear of early NE-trending dextral strike-slip faults and late NW-trending sinistral strike-slip faults in northern Shabei area, and shows the characteristics of conjugate strike-slip.Note: This paper was accepted into the Technical Program but was not presented at the 2019 SEG Annual Meeting in San Antonio, Texas.Keywords: faults, field experiments, geologyPermalink: https://doi.org/10.1190/segam2019-3216029.1FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2019ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2019 Pages: 5407 publication data© 2019 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 10 Aug 2019 CITATION INFORMATION Tao Li, Bu Shaofeng, Hua Xiaoli, Hu Hewei, and Sun Longfei, (2019), "The physical simulation of the conjugate fault in ShaBei structural zone of Northwest Bozhong Sag, Bohai Sea," SEG Technical Program Expanded Abstracts : 3855-3858. https://doi.org/10.1190/segam2019-3216029.1 Plain-Language Summary Keywordsfaultsfield experimentsgeologyPDF DownloadLoading ...
