| 摘 要： | 贵州铜仁坝黄磷矿稀土元素分析结果表明，磷块岩及其围岩具显著的Ce负异常，说明磷块岩是大陆边缘海盆较深水沉积产物，其沉积构造环境与区域岩相古地理研究结论一致，证明Ce异常是示踪沉积古构造环境的良好指示剂.

| Abstract: | Rare earth element analysis reveals that the phosphorite and wallrock in the Bahuang phosphorite deposit show a remarkable negative Ce anomaly,indicating that the phosphorite is typical marine sediment deposited in ancient pericontinental sea with relatively deep water.Such sedimentary tectonic environment is in accord with the conclusion by the regional lithofacies paleogeographic study,suggesting that the Ce anomaly is a good tracer for sedimentary paleo-tectonic environment. |
