摘要
概述了攀西地区碱性岩类产出的地质背景，岩体的主要特征。根据岩石中暗色矿物与主要成矿元素的关系，划分为两大矿化类型：与基性超基性岩有关的含铌、钽碱性岩脉矿床和含钇、铌碱性花岗岩矿床；与花岗岩类有关的含氟碳铈矿霓石碱长花岗岩矿床。并指出这两大矿化类型的成矿条件和找矿前景。
Geological setting and main features of alkali series in Panzhihua-Xichang region are outlined.According to the correlation between dark minerals in the rocks and main ore-forming elements, the ore deposits are divided into two types: alkaline dyke-hosted Nb-Ta ore deposits and alkali granite-hosted Y-Nb ore deposits associated with ultrabasic-basic rockbodie and aegirine-alkali-feldspar granite-hosted bastnaesite ore deposits associated with granitoids. Metallogenetic conditions and prospecting perspective for this two types are pointed out.
