摘要: 平衡剖面技术是一种按照几何守衡原则而建立的地质剖面正演方法,是一种构造变形恢复的重要手段。研究中采用了Geosec软件对焉耆盆地9条构造剖面进行了复原和地层伸缩量计算。结果表明,燕山早期焉耆盆地处于弱挤压状态,构造变形量相对较小,而主要的变形量集中于燕山晚期和喜山期,并且喜山期变形稍弱于燕山晚期。平面上盆地西部变形量较大,东部变形量较小。盆地中、新生代的演化划分为3个主要阶段:燕山早期弱挤压与同生变形阶段,燕山晚期强烈挤压阶段,喜山期对冲挤压阶段。

Abstract: Balanced-section technique is a forward-inversion method of geologic section. which is based on geometric conservation principle. It is an importantmeans for the recovery of structural deformation.During study, usingGeosec technique tomake balanced sections of the 9 seismic lines and calculate the amountof extension and contraction of the for layer. The results show that
Yanqi basin is inweakly compressive status in earlyYanshanian with smaller amount of structural deformation. While main deformation is concentrated in lateYanshanian and Xishanian, but the deformation isweaker inXishanian than that inYanshanian.on the plane, deformation is stronger inwest than that in the east of the basin, mesozoic-cenozoic evolution of the basin is divided
into 3 stage, such as weak compression and syn-deformation stage in earlyYanshanian, strong compression stage in lateYanshanian and face compression stage in Xishanian.

Key words: balanced-section, structural-evolution, structural-deformation, Yanqi-basin
