摘要
桐庐沈村船山组深灰色灰岩 ,厚 12 6 .35 m ,与下伏地层黄龙组、上覆地层梁山组均为整合关系。船山组可划分为 3个化石带 ,上部为 Eoparafusulina pseudosimplex带 ,归属隆林阶 ;中部为 Sphaeroschwagerina subrotunda带 ,归属紫松阶 ;下部为 Triticites subcrassulus带 ,归属逍遥阶。
The Chuanshan Formation is exposed near the Shencun village of Tonlu County, consists of dark-grey massive limestones, 126.35m in thickness. It is conformably underlain by fhe Huanglong Formation and conformably overlain by the Liangshan Formation. The Chuanshan Formatin can be generally divided into three fusulinid zones,the upper Eoparafusulina pseudosimplex Zone (the Longlinian Stage), the middle Sphaeroschwagerina subrotunda Zone (the Zisongian Stage) and the lower Triticites subcrassulus Zone (the Xiaoyaoan Stage).
