Genesis, Characteristics and Prespecting Marks of Phosphorus Deposits in Huaning, Yunnan Province

Article Preview

Abstract:

This article mainly analyzed and discussed the origin of exposed phosphate rock mine in Huaning area.We preliminary think the ore was started from basin phosphate deposits in the early and get rich from transportation and modification by the water repeatedly.Also at the diagenesis phase ,the Eh value is lower and Ph value is higher which makes phosphate concentration of interstitial water higher.With the affection of rich phosphorus interstitial water,the sediment get further phosphatization and makes the rock more rich.At the same time ,the calcium phosphate of intergranular water cements particles what makes the apatite has the characteristics of girdles.The analyzation leads that the cause of formation of phosphorus deposits in this area was sedimentation and modification.
