摘要(Abstract)：

为有效保护我国第一个"金钉子"——浙江常山黄泥塘剖面的同时,又能较好地满足一般性补充研究的需求和普通大众对"金钉子"剖面化石的兴趣爱好,剖面保护单位在"金钉子"剖面附近水库边开辟了一条新剖面。该剖面地层序列完整,出露新鲜,自下而上包括印渚埠组上部、宁国组和胡乐组下部。剖面化石丰富,保存精美,除丰富的笔石外,还含有一些腕足动物、三叶虫、叶虾类和粪化石,自下而上可识别出Corymbograptus deflexus带、Azygograptus suecicus带、Exigraptus clavus带、Undulograptus austrodentatus带和Acrograptus ellesae带等笔石带。整个剖面的岩石和笔石序列与黄泥塘"金钉子"剖面一致,能进行良好对比,可作为"金钉子"剖面的一般性替代剖面,从而为进一步开展达瑞威尔阶的后层型研究提供了新的证据来源。
