摘要

对博格达山前北三台地区大量二、三维地震剖面进行了分析与解释 ,并建立了该区的构造格架。北三台凸起是研究区的主体 ,构造特征可概括为一核、二坡、三鼻、四断和多条环形地层尖灭线。发育的断裂多为区域性的 ,由于受造山带隆升的影响 ,断裂的长期活动控制了地层的沉积及岩相的展布。对地震剖面和古地质图的分析表明 ,北三台地区的构造形成与演化受博格达造山带隆升产生的压陷挠曲作用控制。依据造山带隆升过程 ,将研究区的构造演化分为造山期压陷挠曲盆地发育阶段、弱挤压挠曲性质的陆内坳陷发育阶段、陆内坳陷压陷盆地发育阶段和再生前陆盆地发育阶段。其中海西运动晚期和燕山运动中期 (Ⅱ幕 )对研究区的构造格局起了定型作用
Many seismic profiles of Beisantai region in Bogeda mountain was analyzed, and the structural framework of this region was established. As the principal part of studied region, Beisantai uplift has some typical structure features including one core, two slopes, three nose structures, four faults and multiple circle line wedge-out. Owing to the influence of orogenic belt uplift, the regional faults moved over a long time and controlled the sedimentation and litho-facies distribution. The analyzed results of seismic profiles and paleo-geology maps show that the compressive and flexural deformation resulted from the uplift of Bogeda orogenic belt controlled the formation and evolution of Beisantai region. According to the uplift process of orogenic belt, the tectonic evolution of Beisantai region can be divided into four stages including the compressive and flexural deformation stage during orogeny, the intercontinental depression stage with light compression, the intercontinental depressive and compressive basin, the regeneration foreland basin. Late hercynian and middle Yanshan tectonic movements controlled the tectonic patterns of Beisantai region.
