摘要: 新疆尉犁且干布拉克蛭石矿床是中国最大、世界上为数不多的超大型蛭石矿床之一。通过与世界同类矿床对比研究发现,尉犁且干布拉克超大型蛭石矿床无论是含矿杂岩体的岩石组合类型,还是形成的矿物系列都与世界同类矿床不尽一致,世界上产有超大型蛭石矿床的杂岩体均发育有典型的过碱性岩类,如霓霞岩、磷霞岩、霞石正长岩类等,但且干布拉克杂岩体不含典型的过碱性岩类,矿床与富碱质超基性岩-碳酸岩有关。本文通过野外和室内研究,对含矿杂岩体的区域地质背景、岩体地质及含矿性特征、岩石化学、微量元素、稀土元素、稳定和放射性同位素进行研究,进而建立该矿床的成岩成矿模式,即地幔交代、裂谷作用、岩浆活动、热液蚀变和表生作用,对进一步在塔里木周边寻找和研究该类矿床具有理论指导与实践价值。

Abstract: The Yuli vermiculite deposit is the largest vermiculite deposit in China and also one of the Super-large vermiculite deposits in theworld.Through comparative studies on similar deposits in other areas of the word,other Super-Large vermiculite deposits are characterized by existence of associated peralkaline rocks,e.g.ijolite,urtite and nepheline syenite etc.,indicating that vermiculite mineralization are linked to peralkaline magmatism.However,the Yuli vermiculite deposit has different rock type and mineral series.Because ofabsence of such kind of peralkaline rocks,the Yuli vermiculite deposit is suggested to have a close relation with alkali-rich ultramafic rocks and carbonatites.Based on detailed studies on regional geological background,rock,petrochemistry and geochemistry,a petrogenic and metallogenic model of this deposit is established.The metallogenetic process is followed by mantle metasomatism,rifting,magmatic activity,hydrothermal alteration and supergene weathering.This model has both profound theoretical and practical significance to survey new vermiculite deposits around the Tarim Basin.
