湖北省宜昌磷矿东部整装勘查区地质特征及找矿远景
Geological characteristics and prospecting prospect of the eastern integrated exploration area of Yichang phosphate deposit,Hubei Province
摘要
Abstract
The eastern assembly exploration area of Yichang phosphate mine is located at the junction of Yuan'an County,Baokang County and Yiling District of Hubei Province,where the phosphate layers are deposited in Duoshantuo formation of the Lower Sinian system,and there are three-layer industrial phosphate layer of Ph13,Ph21 and Ph22,which is about 26180m long along the strike,about 9190m wide along the trend,and the buried depth of the ore body is 174.05～1710.20m.A total of 1.847 billion tons of resources of industrial phosphate ore with the inferred levels and higher levels were submitted.The deposit of Yichang phosphate rock is sedimentary type,and the metallogenic period is neoproterozoic,and the metallogenic action is mainly chemical effects of colloids,followed by biochemical action.Ore bodies are controlled by ore-bearing strata,which is enriched in the specific lithographic paleogeographic environment.In this paper,four prospecting target areas including Wujialing and Liujiaping are delineated in the eastern blank area of the integrated exploration area,and it is predicted that the new resources can be increased by more than 1 billion tons,and the prospecting potential is huge.关键词
