| Abstract: | Proterozoic metamorphic rocks are widely outcropped in Anyi area of Mouding. ＂Dawan-type＂ poor magnetite deposit is in the epimetamorphic magnetite-beating greenschist of Proterozoic Longehuan Group Gu- mo Formation Member Ⅲ, the surface high precision magnetic anomaly is very consistent with the ore-beating bed, the ore deposit belongs to the intermediate-basic volcanic--sedimentary metamorphic type poor magnetite depos- it. The ore deposit has become medium-large scale by the exploration in many years, with good prospecting potenti- ality. |
