黑龙江省鸡西—勃利含煤盆地层序地层学讨论

Jixi-Boli coal-bearing basin stratigraphic sequence,Heilongjiang Province

本文以层序地层学理论为依据,对鸡西—勃力盆地与龙爪沟盆地进行了层序划分,可分五个级别的层序,一至三低频层序主要受区域性断裂控制,四、五两个高频层序,主要受气候和局部构造控制。文中简要地叙述了一、二级层序的构造事件及相当的群、组,并以三级层序为主线较详细地论述了三、四级层序的控制因素,岩与岩相特征,古气候条件,层序形成时限以及四级层序的短期基准面旋回与分布。

Taking the sequence stratigraphy theory as a basis,the Jixi-Boli Basin and Longzhaogou Basin can be divided into five stratigraphic sequences,The first,second and third low frequency sequences are mainly controlled by the regional faults;the fourth and fifth high frequency sequences are mainly controlled by climate and part structures.The paper narrated the first-level,the second-level sequence structure events and the suitable Group and the Formation,the third,fourth level of sequence controlling factors,r...
