摘要
安徽省淮南、寿县一带前寒武纪淮南群寿县组,由一套细致微粒的陆源碎屑岩所构成。据岩性及原生沉积构造划分为24层,组合为六个韵律;对其中11个层作薄片粒度分析,表明其物质来源系由河流搬运沉积在浅海盆地后,又经受波浪式潮汐作用的改造。其沉积环境属河控三角洲类型,沉积深度大致应在浪基面(或风暴浪基面)附近及潮间带的范围内。
The Shouxian formation of Huanan Group in Huanan and Shouxian in Anhui Province , are Composed of a set of fine-tiny grained terrigenous clastic rocks. According to its character of rocks and the sedimantary structure . the formation can be divided into 24 beds, be Combined into 6 sedimantary rhythms .
