| 摘 要： | 在中国南华系层型剖面优选区之一--湘黔桂交界区,富禄闻冰期可再分为3个相对较暖热的气候阶段(间冰段)和2个相对寒冷的气候阶段(冰段),即(自老而新):三江间冰段、龙家冰段、烂阳闻冰段、两界河冰段、大塘坡间冰段.相应地,富禄间冰期沉积地层--富禄组可分5个段,即:三江段、龙家段、烂阳段、两界河段、大塘坡段.另外.对古城组和铁丝坳组层型的湖北长阳古城剖面、贵州松桃大塘坡剖面和相关资料的再研究揭示,"古城组"和"铁丝坳组"都是富禄间冰期晚冰段(即两界河冰段)的沉积,均不宜替代长安组作为南华纪早冰期沉积的代表.

| Abstract: | The region which Fulu Formation stratotype section is situated at is the one of the preference places of Nahua System stra-totype section in Hunan-Guizhou- Guangxi border region in South China. Fulu interglacial epoch can be divided into three warm climate periods and two icy climate periods.They are named as Sanjiang intersatial, Longjia icy stage, Lanyang intersatial, Liangjiehe icy stage and Datangpo intersatial. The strata corresponded with Fulu interglacial is Fulu Fomation. It is divided into five members which are Sanjiang Member, Longjia Member,Lanyang Member, Liangjiehe Member, Datangpo Member. After studing Gucheng Formation stratotype section in Changyang, Hubei Province and Tiesiao Formation stratotype section in Datangpo, Songtao County, Guizhou Province, it showed that both Gucheng Formation and Tiesiao Formation were formed in later Fulu interglacial epoch. They can not substitut for Chang'an Formation as the strata representation in early Nanhua System glaciation period. |
