安徽庐枞矿集区何家大岭铁矿床铁氧化物微量元素特征及其指示意义
Geochemical characteristics and metallogenic implications of iron oxides and trace elements in the Hejiadaling iron deposit,Lu-Zong Ore Cluster,Anhui Province
摘要
Abstract
The Hejiadaling iron deposit,a representative porphyritic-type mineralization in the Lu-Zong ore cluster,exhibits vertical zoning from deep magnetite through hematite to shallow pyrite,with hematite predominating.Micro-area analysis reveals trace element partitioning in iron oxides:Mg,Ca,Al,Co and Ni demonstrate water-rock interaction signatures,Ti exhibits temperature-dependent behavior,while Mn and Zn reflect combined thermal,fluid-chemical and reaction-intensity controls.Vanadium distribution correlates with oxygen fugacity variations.Paragenetic minerals show negligible influence on iron oxide trace element signatures.The magnetite→hematite→pyrite transition sequence and hematite dominance confirm Hejiadaling's classification as an IOA-type deposit.关键词
