摘要
鸡西煤盆地为一中、新生代断(拗)型构造盆地,沉积了中、新生代两套含煤地层。通过对盆地沉积地层及构造特征分析,对盆地构造演化史进行探讨,归纳总结出鸡西煤盆地具有3次大型裂陷和5期构造应力场的变化,才形成现今的构造格局。
Jixi coal basin is a tectonic basin of mesozoic and cenozoic fault-depression type, and deposited mesozoic and cenozoic coal-bearing strata, Thorough the analysis of basin sedimentary strata and tectonic features, this paper discussed the basin tectonic evolution, and summarized the current tectonic framework of Jixi coal basin are caused by three major rifting and change of five-phase tectonic stress field.
