| 摘 要： | 山西柳林成家庄剖面太原组发育7层灰岩,从下到上依次为半沟灰岩、吴家峪灰岩、庙沟灰岩、下毛儿沟灰岩、上毛儿沟灰岩、斜道灰岩和东大窑灰岩。通过详细的野外观测和室内镜下薄片研究,确定了各层灰岩的沉积相类型,恢复了当时的沉积环境和各层灰岩沉积时相对水体深度的变化。其中庙沟灰岩属中缓坡相沉积,吴家峪灰岩、下毛儿沟灰岩、上毛儿沟灰岩、斜道灰岩和东大窑灰岩均属浅缓坡相沉积,半沟灰岩属后缓坡相沉积。7层灰岩的相对水体深度关系为:庙沟灰岩>斜道灰岩>东大窑灰岩>下毛儿沟灰岩>上毛儿沟灰岩>吴家峪灰岩>半沟灰岩。在太原组内识别出6次沉积间断、7次小型沉积旋回,总体构成2次明显的相对海平面升降旋回。

| Abstract: | Seven beds of limestone are developed in the Taiyuan Formation of the Chengjiazhuang Section in Liulin,Shanxi Province.From below upwards they are:Bangou Limestone,Wujiayu Limestone,Miaogou Limestone,Lower Maoergou Limestone,Upper Maoergou Limestone,Xiedao Limestone and Dongdayao Limestone.The types of sedimentary facies of those beds of limestone are determined and their sedimentary environments and relative water depths during deposition of limestone of various beds are reconstructed by detailed field observations and thin-section examinations.Of them,the Miaogou Limestone is considered to be of middle ramp facies,the Wujiayu Limestone,Lower Maoergou Limestone,Upper Maoergou Limestone,Xiedao Limestone and Dongdayao Limestone are all shallow ramp facies deposits and the Bangou Limestone belongs to back ramp facies.Their relative depths are Miaogou Limestone > Xiedao Limestone > Dongdayao Limestone > Lower Maoergou Limestone > Upper Maoergou Limestone > Wujiayu Limestone > Bangou Limestone.In the Taiyuan Formation of the Chengjiazhuang section six sedimentary gaps and seven minor sedimentary cycle are recognized,which form two sedimentary cycles of higher order with marked relative sea-level fluctuations. |
