    云南中部侏罗系研究新进展

    New progress in the study of the Jurassic of central Yunnan

    • 摘要: 依据禄丰县川街剖面修订了昆明小区曾经使用半个多世纪的上、下禄丰系(群、组)岩石地层单位,厘定并重新命名了禄丰组(包括沙湾段和张家坳段),新建川街组、老罗村组、麻地山组,沿用安宁组,首次在禄丰区域内划分出上侏罗统。结合各组产出的化石,建立起侏罗纪早、中、晚3套脊椎动物群序列。进一步的考察研究又确认出昆明小区存在上三叠统舍资组和侏罗系的连续沉积。通过对比,确定昆明小区中侏罗统川街组底部和上侏罗统安宁组顶部,缺失楚雄小区张河组下部“绿砂岩段”和妥甸组上部“黄色泥岩段”。首次发现晚侏罗世妥甸组昆虫化石,昆虫化石的类型和叶肢介等门类化石有别于北方动物群。依据这些研究成果提出康滇地层分区侏罗系对比方案。
