摘    要:该区之南河断裂及雅龙江断裂是成岩成矿流体的通道,控制了矿带的展布。哈哈、棉沙湾次级断裂带的有利部位直接控制了矿床的产出,更次级的断层、节理为矿脉、矿体提供了良好的赋存空间;霓石碱性花岗岩是稀土成矿的直接母岩,矿床与之紧密共生。含矿杂岩体的生成过程就是稀土成矿的过程,它的发育程度,决定矿床规模和价值,成矿带内已发现的稀土矿床均为充填断裂带的脉型矿床。深部构造+北北东走向地壳深断裂带+幔质碱性杂岩体“三位一体”是基本的成矿条件和模式。区内具有良好的找矿远景。

关 键 词:成矿带,成矿条件,霓石花岗岩株,稀土矿床,冕西

Abstract:Nanhe and Yalongjiang fractures as conduits of magma and ore fluid get the metallogenic belt under control,while the deposits are controlled directly by Haha and Mianshawan fractures with ores of REE filling in the associated faults and joints. The deposits of REE are hosted by aegirine-granite.The Ore-forming process was associated with the petrogenic process. The discovered deposits are vein-type ones which fill in fracfure. "Three in one" of deep-seated structures and NNE-trending faults with alkaline complex is fundamental conditions for the ore-formation of REE.
Keywords:metallogenic belt  metallogenic conditions  aegirine-granite stock  deposit of REE  west Mianning
