多瑟欧盆地三元结构型反转构造形态及其指示意义
Morphology and indicative significance of ternary structural inversion structures in the Doseo Basin
摘要
Abstract
Ternary structural inversion structures are one of the most typical structural styles in the Doseo Basin,but research on their geometric characteristics,genetic mechanisms and geological significance remains entirely unex-plored.Based on theories of plate tectonics,structural geology,petroleum geology and sedimentology,this study applies techniques such as seismic fine interpretation and structural analysis to investigate the geometric characteris-tics and geological significance of the ternary structural inversion structures in the Doseo Basin.The results indicate that ternary structural inversion structures can be divided into three types based on boundary convergence degree:bilateral strong convergence type,bilateral weak convergence type,and unilateral convergence type;based on mir-ror plane morphology,they can be divided into recumbent S-type,sickle-shaped,and approximately straight-line types;tectonic inversion during the Late Cretaceous Santonian and Maastrichtian periods controls the formation of ternary structural inversion structures;the widely developed ternary structural inversion structures throughout the basin clearly indicate that the basin inversion intensity is moderate;on the plane,ternary structural inversion struc-tures are distributed near the Borogop Fault,some are located between the Borogop Fault and the eastern inverted anticline zone I,and on the eastern inverted anticline zone I.These areas all represent significant future exploration targets.The research results have guiding significance for deepening and enriching inversion structural styles and in-version structural theory and provide certain technical support for oil and gas exploration deployment.关键词
