| 摘 要： | 保山金鸡剖面丁家寨组下部含砾层的双层结构特征与不同的地质作用有关:下部砾岩层为滨海相砾岩;上部角砾状灰岩由碎屑流产生。所产遗迹化石指示滨海相环境。根据保山地区丁家寨组的颗粒成分、胶结物及地球化学特征,对丁家寨组冷温水成因的观点提出了质疑

| Abstract: | The pebble bearing layerin the lowerpartofthe Dingjiazhai Formation in Jinji section,in Baoshan region ofwestern Yunnan,can be divided in to two parts:the pebble bed ofnormallittoralfaciesbelow and the brecciated limestone above.Thetrace fossil Ti soa jinjiensis from the superstratum ofthe pebble bearing layer may be attributed to the Skolithosichnofacies,indicating a high water energy littoralenvironments.The abundant and diverse fossils(corals,fusulinids,etc.) ,the characteristics of cements in the lime stonesand the thick and stablegypsum bed indicatethatthe Dingjiazhai Formation wasde posited in warm waterenvironments. |
