牟定安益地区元古界龙川群变质岩地层及侵位于其中的基性超基性岩体出露较广，近期工作发现了产于路古模组第三段绿片岩中的超贫磁铁矿及产于基性超基性岩体中的含铂钯超贫磁铁矿两种铁矿化类型，该区具有找超贫磁铁矿的前景。

In Anyi area of Mouding County, Proterozoic metamorphic strata of Longchuan Group and basic-ultrabic intrusive bodies that invaded into the strata are extensively distributed, Recently, two kinds of mineralization types were discovered, which are ultra-poor magnetite in 3rd member greenschist of the Lugumu Formation and Pt-, Bd-bearing ultra-poor magnetite in ultrabasic-basic intrusive bodies. It is thus held that there exists the prospect in search for ultra-poor magnetite deposits in this area.
