论文摘要
目前浙赣三山地区"金钉子"尚无精确的同位素年龄数据.基于钾质斑脱岩SHRIMP锆石U-Pb测试,三山地区早-中奥陶世宁国组Azygograptus suecicus带中部、Exigraptus clavus带底部、Acrograptus ellesae带中部的同位素年龄分别为482.9±6.1 Ma、477.6±8.3 Ma和467.0±4.4 Ma,为华南地区中奥陶世大坪阶和达瑞威尔阶底界的全球界线层型（GSSP）开展地层对比提供了精确的同位素年代学依据.结合生物带对比,大致将浙西地区早-中奥陶世普遍存在的地层缺失事件的发生时限界定于482.9～477.6 Ma之间,即杭州-嘉兴台地缺失牙形刺Oepikodus evae带-Lenodus anticariabilis带（或笔石Azygograptus suecicus带-Acrograptus ellesae带）地层,其代表了郁南运动在浙西地区的具体表现,拉开了华南地区早古生代构造运动的序幕,也可能是欧洲加里东造山过程中亨伯运动和塔康运动的远程响应.
