Boluotou Orebody
Including the Boluotou Orebody.
In the Eastern Contact Orebody, iron orebodies occur in ore-hosting dolomites and the alteration zone between them and country rocks. These iron orebodies are lamellar or lentoid, occurring parallel to the dolomite carbonatites. They are paragenetic or associated with REE and niobium ores. The iron ores associated with niobium and REE ores account for 19.89% and 80.07% of the total iron ore resources of the block, respectively, while pure iron ores only make up 0.04%. A total of 24 iron orebodies, four REE orebodies, and 10 niobium orebodies have been identified in this area, amounting to 38 orebodies.
