| 摘 要： | 本文概略介绍了牦牛坪稀土矿床特征,讨论了成矿时代,分析了成矿条件,初步总结了成矿规律,探讨了成矿物质来源、成矿过程及成矿机理,提出该矿床为上地幔部分熔融基性—超基性岩浆多期多阶段分异演化高侵位云煌岩-霓石碱性花岗岩-碱性基性伟晶岩-方解石碳酸岩型单一氟碳铈矿稀土矿床。初步建立了北北东向断裂系统加帽源碱性含矿杂岩体二元成矿模式,指出了进一步找矿远景区段。

| Abstract: | The present paper has described geological characteristics and has made an approach to the epoch of mineralization, ore-forming conditions and metallogeny including source of ore-forming elements, ore-forming process and ore-forming mechanism of Maoniu-ping ore deposit of rare-earth elements which is a rare-earth-bearing minette-aegirine-granite-alkali pegmatite-calcite carbonatite deposit. The host rocks were formed by partial melting of upper mantle. A binary metallogenetic model containing NNE-trending fracture system with mantledervied ore-bearing alkali complex has been established. Point out potential prospecting targets. |
