【摘要】 埃迪卡拉纪（635～539 Ma）记录了大气海洋的重要氧化、早期动物的快速演化和碳循环及气候的剧烈波动.然而,与已建立的氧化还原环境、生物和碳循环记录相比,相应的气候记录则极端匮乏.本文采用单个样品多动力学模型方法对已发表的华南陡山沱组保存较好的碳酸盐岩团簇同位素温度(T△47)数据进行固相重排效应校正,获得了埃迪卡拉纪第一条长达～60 Ma的高分辨率古温度记录.该记录清楚表明580-Ma Gaskiers冰期对应于陡山沱组中部地层且相对于海洋氧化,气候的波动对于早期动物的快速演化影响有限.这些发现不仅解决了长期以来人们对Gaskiers冰期在华南地层位置的争论,而且深化了对早期地球气候变化、海洋氧化与后生动物辐射关系的认识.更多还原
