Search Direction for Manganese Ore in the Surroundings of Presinian Bikou Ancient Land

We set forth different understandings of whether the position of manganese-bearing ore belt belongs to Jixian,Sinian period or Cambrian period in the east and in the surroundings of Presinian Bikou ancient land,the article analysis and research follows that manganese-bearing rock series are the deposits in Sinian-Cambrian period overlying on the Presinian Motianling antichinorium folded belt belonging to the contemporaneous deposit(i.e.,Upper Sinian Series).Owing to the different geological structural setting and different sedimentary environment,high-quality manganese ore concentrates in the southern belt; while the manganese ore with high phosphorus is located in the northern belt,where infiltration manganese deposit by weathering process formed in the favorable positions for structure and rock series.We also give suggestions about the criteria for ore prospecting and search direction for manganese.
