天津蓟州锰方硼石矿床地质特征及资源潜力
Geological characteristics and resources potential of chambersite deposit in Jizhou district,Tianjin city
摘要
Abstract
Chambersite occurs in Jizhou district and the ore occurrences have found at Dongshuichang,Qianganjian,Baqianyu and Daanping etc.Chambersite ore occur in Member 2 of Gaoyuzhuang formation of Jixian Period.The body is controlled by strata.Geneticaly the ore is sedimentary-reworked type formed in Gaoyuzhuang Stage.Ore bodies occur in lense,lenticle,cake,string of beads and irregular mass.Chambersite,rhodchrosite,pyrite,hematite,chalcopyrite,psilomelane,pyrolusite and limonite are the ore minerals,Fe-dolomite,quartz,feldsoar and clay minerals gangue mineral.Carbonization,tourmalinization and weak silicification are the wall rock alteration.River sedimentation geochemical sur-vey at scale 1∶50000 shows the ore-caused anomaly Ht-1 and Ht-2 and two ore occurrence corresponding to the above anomalies are found.Compared with typical chambersite deposit we consider that manganif-erous shake is direct mark,single element anomaly of Mn,B and As,the Mn-B-As comprehensive anom-aly,the effective geochemical mark for prospecting chambersite deposit in the area.Based on metallogenic geological characteristics of the chambersite deposit and analysis of typical Chambersite deposit this paper summarizes prediction elements of the mineral resources and uses geological and geochemical information to build the prediction model.Five targets are outlined with comprehensive information geological unit method.The potential chambersite mineral resources in the area is estimated to be 295 X 104 t with the method of volume of the ore-bearing geological body.关键词
