| 摘 要： | 对贵州织金三甲地区寒武系底部戈仲伍组含磷岩系稀土元素、微量元素和一些常量元素等在剖面上的变化规律进行系统的研究，并结合剖面上小壳动物化石富集特点，认为寒武系底部戈仲伍组中有两个磷和稀土成矿期，稀土含量与磷含量成显著的正相关关系，而与小壳动物化石丰度没有显著相关性。

| Abstract: | The phosphate concretions from Gezhongwu Formation were researched systematically on the Sanjia section, Zhijin, Guizhou. Based on the variation rule of REE, trace elements, major elements and oxidates, combining with the beneficiation character of small shelly fossils. It is found that small shelly fossils from the bottom of Cambrian contribute to the phosphate concretions is not important. It is suggested that there are two ages of forming phosphorus, and the first is important. The phosphate concretions have a good relationship with the phosphorite, but not the small shelly fossils. |
