| 摘 要： | 本文通过对该区含煤盆地的分布、含煤地层、构造规律、沉积环境和聚煤特征的研究,划分了区内的构造型式,即松辽盆地南缘总的构造型式为直扭构造体系,具有天山—阴山纬向构造带和双辽—铁岭—大孤山经向构造带,不同次序、不同级别的构造控制矿产的赋存和分布,形成了三种不同的煤田沉积类型并各具其特征,东西、南北向构造是本区的构造格架,它们的运动方式与方向及其派生的分枝构造是控盆聚煤的分布与沉积类型的重要因素,控制聚煤盆地的展布与沉积类型,决定了聚煤的发育程度。

| Abstract: | Based on research of the distribution of coal-bearing basin,coal-bearing strata,tectonic regularities,sedimentary environment and coal-accumulation features,divides tectonic type in the region,namely the total structural types in south rim of Songliao Basin is structures resulting from linear shearing,with the Tianshan-Yinshan latitudinal tectonic belt and Shuangliao-Tieling-Dagushan meridional tectonic belt.Different orders and different levels tectonic controlled occurrence and distribution of minerals,formed three different coalfield sedimentary type with different features,EW-SN structures is the tectonic framework of this area.the way their mode and direction of motion,and its derivative branch tectonic are important factors in distribution of basin-controlling coal accumulation and deposition types.Distribution and sedimentary type of controlling coal-accumulation basin,determines the development degree of coal-accumulation. |
