| 摘 要： | 通过野外地质调查、岩石学、矿相学等研究手段,在柴达木盆地北缘鱼卡及铁石观一带均发现榴辉岩型金红石矿床,其单个矿体长可达千米以上,宽均达几米至几十米不等,金红石物相Ti平均品位可达2.58%,属于高钛榴辉岩的范畴,且其矿床地质特征与大别—苏鲁地区的金红石矿床特征极为相似。鱼卡和铁石观金红石矿床的发现,填补了柴北缘榴辉岩变质带没有金红石矿床的空缺,并暗示柴北缘地区有发现大型榴辉岩矿床的找矿远景。

| Abstract: | With such means as field geological survey, petrology and mineragraphy, the authors found eclogite-type rutile deposits in Yuqia-Tieshiguan area on the northern margin of Qaidam Basin. A simple orebody is over 1 km in length and from a few meters to tens of meters in width. The average grade of titanium phase in rutile is 2.58%, belonging to high titanium eclogite, and the deposit geological characteristics are very similar to the rutile deposit characteristics of Dabie-Sulu area. The discovery of rutile deposits in Yuqia-Tieshiguan area fills the gap of the lack of rutile deposits in the North Qaidam eclogite metamorphic belt and also suggests that the North Qaidam region has an exploration prospect of finding large-size eclogite deposits. |
