三官塘铁矿位于安徽省马鞍山市,地处宁芜火山岩盆地中段,矿床成因类型为玢岩铁矿--中高温热液充填型矿床。文章通过对其成矿地质特征的分析研究认为:岩浆沿基底断裂上侵,在结晶末期发生了钠长石化、磁铁矿化等作用形成了早期的含矿热液,沿岩石裂隙和矿物颗粒间隙向岩体顶部运移,形成以浸染状为主的现今三官塘铁矿。

The Sanguantang Iron ore deposit in Ma‘anshan City, Anhui Province, in the middle part of Ningwu volcano-sedimentary basin. The Mineral genesis is porphyrite iron ore--medium-high temperature hydrothermal deposits. this paper found that Iron mineralization is control ed by diorite-porphyrite, the Magma intrusion along the basement fault,the ore-forming hydrothermal solution of the early stage migrates mainly in the form of Albite, magnetite etc In the crystal ization stage,Going to Top of the Rock Along the rock fissure and mineral particles clearance,formation main Disseminated of present-day Sanguantang Iron.
