塔里木盆地中生代沉积演化
Mesozoic depositional evolution in the Tarim Basin
摘要
Abstract
In view of the analysis on Mesozoic sedimentary evolution in Tarim Basin,layer flattening technique was applied,and chronostratigraphy analysis of two seismic survey lines was completed,seismic cross sections were interpreted for each Mesozoic formation,and twelve residual time thickness maps were compiled for the first time.Based on these data,a preliminary sedimentary evolution analysis on the Mesozoic strata was conducted.Influenced by the Indosinian movement,the Mesozoic depocenter of the Tarim Basin shifted eastward from the Awati Sag during the Triassic.Subsequently,under the influence of the Early Yanshan movement,it continued to shift further eastward into the Manjiaer sag during the Jurassic.During the Cretaceous,the Manjiaer Sag was generally characterized by lacustrine transgression,under the influence of the Middle Yanshan movement,the deposition range expanded,the depocenter moved back to the northwest.Affected by the Indosinian and Yanshan movements,the Tadong uplift underwent rigid deformation,and fractures developed in the Jurassic strata.During the Early Cretaceous,the Tarim Basin as a whole experienced a broad and gentle extensional subsidence.In the Late Cretaceous,the basin underwent regional uplift and erosion due to the Late Yanshan movement.Mesozoic strata are characterized by fluvial-lacustrine sedimentation.关键词
