| 中文摘要: |
| 丁叉叉山地区金红石矿床位于柴北缘成矿带东端,为近年新发现的大型金红石矿床。矿床产于古元古界金水口群地层榴辉岩体中,严格受榴辉岩体的控制。呈条带状、透镜状产出,近东西向展布。成因类型属榴辉岩型金红石矿床,成矿时期为加里东期。在总结区内矿床地质特征的基础上,进而与国内苏鲁榴辉岩金红石矿床、省内鱼卡榴辉岩型金红石矿床等典型矿床对比分析,研究表明:区内榴辉岩成矿条件有利,保存条件良好,具有较好的找矿前景。 |
| 英文摘要: |
| Rutile deposit in area of Dingchacha Mountains, locating in the eastern part of northern margin of Qaidam Basin Metallogenic Belt, is a newly discovered large rutile deposit in recent years. The rutile deposit is concentrated in the eclogite of Paleoproterozoic Jinshuikou Group. The ore bodies are strictly controlled by eclogue, in lenticular and banded forms extending to the direction near E-W. The genetic type belongs to eclogue-type rutile deposit, and the metallogenic period is Caledonian. On the basis of summarizing the geological characteristics of the deposit, by comparing with Sulu rutile deposit and Yuka rutile deposit and making analysis, this study shows that eclogite mineralization in the region is favorable, preservation conditions are good and prospect of ore prospecting is relatively good.. |
