摘要
德令哈盆地下侏罗统含煤磨拉石盆地组合是在以冲积扇—扇三角洲沉积体系为主的沉积环境下发育起来的。简要报道研究区冲积扇—扇三角洲体系沉积及其组合特征 ,在此基础上借助马尔科夫链建立冲积扇—扇三角洲体系沉积旋回的结构模式 ,并探讨该结构模式的地质意义。
The coal-bearing molasses basin association of Delingha Mesozoic (early Jurassic)basin was developed on the sedimentary environments mostly alluvial fan-fan delta system. The authors briefly reported in this paper depositional and association characteristics of coal-bearing alluvial fans-fan delta, and by means of Markov model founded the architectural model of the depositional cycles of the alluvial fan-fan delta systems in Delingha basin during early Jurassic. The geological significances on the architectural model is also discussed.
