Exploration of Shallow Structural Characteristics in the Xinyi Segment of the Anqiu-Juxian Fault of Tan-Lu Fault Zone
View through CrossRef
Abstract
The Anqiu-Juxian fault is the most active branch of the Tan-Lu fault zone. As most of the Xinyi segment of the fault is buried, there is little research on such important issues as its shallow structure and spatial distribution. In this paper, the shallow structural characteristics of the Xinyi segment of the Anqiu-Juxian fault are comprehensively studied by the shallow seismic exploration. The results of this study show that: (1) The Anqiu-Juxian fault runs through the entire Xinyi area, with its strike being approximately NNE5°∽15°. (2) The Xinyi segment of the fault follows a single branching–double branching–single branching pattern from north to south. In the single branch section, the fault is characterized by strike-slip thrust, while in the double-branch section, the east and west branches of the Anqiu-Juxian fault are both strike-slip normal faults. The results of this study, for the first time, comprehensively provided seismological evidence of the shallow structure of the Xinyi section of the Anqiu-Juxian fault and basic data for the planning and construction of Xinyi urban.…
