摘要
滴道组沉积地层明显地受基底的起伏形态及同沉积断裂控制,显示为地堑式的裂陷沉积,形成同期的南北2个沉积区;通过对含煤地层滴道组的沉积体系、分布及沉积环境、演化的分析,阐述了鸡西盆地含煤地层滴道组的沉积规律。
The sedimentary strata of Didao Group is obviously controlled by the basement undulate form and synsedimentary fault.The depressed rift deposition of graben type show that two sediment area in south and north formed in the same period.Through analysing the coal-bearing stratum of Didao Group sedimentary system,the distribution,the sedimentary environment and the evolution,describes the deposition rules of Didao group coal-bearing stratum in Jixi Basin.
