地震勘探揭示须水断裂浅部构造特征
Shallow Structural Features of the Xushui Fault Revealed by Seismic Exploration
摘要
Abstract
Absrtact:Three high-resolution seismic reflection profiles obtained from shallow seismic exploration were used to analyze the shallow strata and the basic characteristics of the fault.The results show that the shallow strata of the Xushui fault are in a horizontal shape,with little variation in overall thickness;The Xushui fault strikes east-west and dips north with an apparent dip of 59°-77°and a fault drop of 3-14 m.The shallowest upper break point can be identified with a burial depth of 42 m.Combined with drilling verification,it is considered that Xushui fault is an active fault in the early and middle Pleistocene.关键词
