| Characteristics of Ultra-poor Magnetite Deposits in Anyi Area of Mouding County |
|
|
| Abstract: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. |
