摘要
通过对香山西矿床辉长岩及钛铁矿石中磁铁矿单矿物的稀土元素配分分析,发现磁铁矿既有与其钛铁辉长岩一致的稀土元素配分形式,也存在"三重弯曲"或多重弯曲现象。而且不同辉长岩中磁铁矿的稀土总量差10倍以上。此外,香山西矿床磁铁矿单矿物与钛铁辉长岩具有较高的正铕异常与岩石中大量的斜长石堆晶有关,但成矿环境是否为氧化环境还需进一步讨论。
On the base of study on the REE geochemistry of magnetite from Xiangshanxi Cu-Ni-Ti (V) -Fe deposit, Xinjiang, it was discovered that the magnetite has the same REE pattern with its grabbro, but some REE pattern of magnetite shows particular "triplex curve" model or "multiple curve" model as well. More than 10-fold difference between the total REE of magnetite from different gabbro. In addition, the magnetite and ilmenite gabbro has a high positive Eu anomalies. It might be owing to a lot of rock rubble plagioclase crystals. But metallogenic environment is an oxidizing environment needs further discussion.
