| 摘 要： | 对云南禄丰鸡街超基性碱性岩(霞辉岩)岩石化学、辉石成分、锆石成因类型及其年龄值的意义等进行研究,文章最后对复合型锆石成因进行了论述,并建议将岩浆复合型锆石中的老核称为残留锆石,变质复合型锆石中的老核称为继承锆石。

| Abstract: | From the compositions of major element oxides and mineral of the uhrabasic/alkali rock bodies of Jijie, we obtain that the bodies of Jijie should belong to the natrium uhrabasic/alkali rock. Combined the ages of rocks with cathodoluminescence image of zircon, the old cores of the magmafic compound zircons were partitioned residual zircon. The old cores of the metamorphic compound zircons were partitioned inherited zircon. |
