摘要
通过对黑龙江及呼伦贝尔盟地区晚中生代（Ｊ３～Ｋ１）大地构造背景、火山活动情况、地质和钻井资料等综合研究，提出断裂和火山活动是表征本区构造特征的两个重要方面。按沉积相成因分类法，研究区内Ｊ３～Ｋ１发育的沉积盆地可划分为７种类型。对在不同时间、不同部位的不同类型沉积盆地的发育情况进行分析，归纳出３种盆地演化系列，从而确定了研究区Ｊ３～Ｋ１沉积盆地类型及演化特征。
Fault and volcanic activity are two important aspects in structure features of sedimentary basin in Late Mesozoic era according to the geotectonic background, volcanic activity and geological data of wells. It divided the sedimentary basins into 7 types according to the synthetical classification methed of sedimentary facies origin, then analysed the infilling succession of basin developed in different parts, and got 3 kinds of evolution succession of sedimentary basin. So the types of sedimentary basin and evolution features(J 3￣K 1)were determined.
