摘要
通过对腊菜河铁多金属矿地质特征、矿体和矿石特征进行调查分析,同时结合室内岩相学、矿相学研究,将腊菜河铁多金属矿的形成阶段划分为干矽卡岩、湿矽卡岩、氧化物、铅锌硫化物4个成矿阶段。根据矿体产出地质条件、矿物组合及围岩蚀变特征,同时结合前人资料,认为腊菜河铁多金属矿为接触交代型矿床,燕山期中酸性侵入岩与碳酸盐岩接触部位为重点找矿靶区。
The ore-forming process is divided of the deposit into four stages dry skarn,wet Skarn,oxide minerals,lead-zinc sulfide stage based on the investigation and analysis of the geological characteristics,ore body and ore characteristics of the LaCaihe Fe-polymetallic deposit,combined with petrographic and ore microscope studies.It can be concluded that the LaCaihe Fe-polymetallic deposit belongs to the contact metasomatic deposit according to the ore-forming geological condition,mineral assemblage,wall rock alteration regularity and previous data.The contact zone between Yanshanian intermediate-acid intrusive rock and carbonate is the key prospecting target.
