| 摘 要： | 铁法盆地属于晚中生代的NNE向半地堑煤盆地,北西西系是其主要的成盆期构造.在对铁法盆地的同沉积构造进行重新认识的基础上,划分了纵向同沉积构造单元和横向同沉积构造单元,分析了各同沉积构造单元的聚煤条件、控煤特点,总结出其对富煤带和聚煤中心的控制作用,确定了中部较缓慢沉降带、东部缓慢沉降带中近岸浅水湖泊区及湖缘三角洲平原为远景找煤方向.

| Abstract: | Tiefa basin is a late Mesozoic NNE-trending half gTaben coal-bearing basin, and the NWW structural system is the most important synbasinal structure. Based on analyzing syndepositional structure of Tiefa basin, the vertical and transversal syndepositional tectonic-units were set out and the coal-controlling characteristic and coal-accumulating condition of syndepositional tectonic-units were analyzed and the control action of synbasinal structure acting on coal-rich zone and coal-accumulating contre was summed up. At last, the aspect and prospect area of coal is the shallow alongshore lake country and lake brim delta plain in the center and eastern slow depression area. |
