河南宜洛煤矿寒武系地层中岩石类型较全,沉积构造发育。主要岩石类型有:钙质石英砂岩、含海绿石钙质石英砂岩、纹层状泥灰岩、淀晶砂质粒屑灰岩、鲕粒灰岩、豆粒灰岩、骨屑灰岩、砂屑灰岩、迭层石灰岩、核形石灰岩、凝块石灰岩以及纹层状白云岩和鲕粒白云岩等。沉积构造有纹层构造,薄互层层理、羽状交错层理、冲洗层理、中小型交错层理及粒序层理,波痕,干裂、雨痕,鸟眼构造、冲淤构造、潮渠以及迭层构造、虫迹和包卷层理。文中对它们的特征作了描述,并附有一些照片。在叙述了岩石类型和沉积构造之后,接着分析了各组的沉积环境,最后总结了本区潮上带、潮间带和潮下带的沉积特征。
The rock types of the Cambrian strata in the Yili Mine in Henan Province are quite complete and their sedimentary structures are developed. The main types of rocks are: calcareous quartz sandstone, calc-quartzite sandstone, laminar marlite, lithic sandstone, limestone oolitic limestone, bone limestone, gritstone, Limestone, laminated limestone, karyolite, clinker limestone, laminar dolomite and oolite dolomite. Sedimentary structure with lamina structure, thin interbedded layer, pinnate staggered layering, washing layering, small and medium-sized staggered bedding and sequence stratification, ripple, dry crack, rain marks, birds eye structure, scouring and silting structure, Tidal channels and laminated structure, insect traces and wrapping. The article describes their features, along with some photos. After the description of rock types and sedimentary structures, the sedimentary environment of each group is analyzed. Finally, the sedimentary characteristics of the tidal zone, intertidal zone and subtidal zone in this area are summarized.
