| 摘要: |
| 鄂尔多斯盆地柳林地区早奥陶世冶里期沉积以浅灰色中薄层泥质白云岩为主,发育大量竹叶状碳酸盐岩。不同类型的竹叶状碎屑反映了不同的沉积环境。笔者对研究区剖面内的竹叶状碎屑进行分析和研究后认为,竹叶状石灰岩的形成可以分为早期沉积物的形成和早期沉积物的破碎、搬运和再沉积两个阶段。 |

| Abstract: |
| The sedimentary strata in the Lower Ordovician Yeli Formation,Liulin,Ordos Basin dominantly consist of light grey medium-to thin-bedded muddy dolostones,with well-developed edgewise carbonate rocks.These edgewise limestones have experienced two stages of formation,including the deposition of sediments in the early stage,and then fracturing,transport and redeposition of the sediments. |
