| 摘 要： | 以内蒙古阿尔山地区下寒武统苏中组为研究对象,综合区域地层、岩石结构、剖面特征、粒度分布特征,对苏中组碳酸盐岩夹碎屑岩的沉积环境进行了深入分析.从粒度分布特征来看,苏中组砂岩粒度分布表现出双峰和多峰不对称,偏度以正偏为主,峰度数值多且比较低,分选性差,以粗粒物质为主等特征;运用萨胡图解投点、判别函数计算确定内蒙古阿尔山地...

| Abstract: | Depositional characteristics and environment of the Lower Cambrian Suzhong Formation in Aershan area of Inner Mongolia are analyzed through integrating areal stratum,lithology,section characteristics,and distribution of the grain size.Grain size of the sandstone in the Suzhong Formation presents the following characters: with double or multimodal anisomerous peaks in grain size distribution frequency curves;mainly in positive skewed distribution;numerous but low peak values;poor sorting and most of the grai... |
