摘要
红旗岭镍矿田是我国岩浆岩型铜镍硫化矿床的主要矿化集中区之一,茶尖矿区是其重要组成部分之一.在茶尖矿区已往勘查中共发现20余个镁铁-超镁铁质岩体,并在1号、新6号、9号、18号岩体中发现小型铜镍矿床,2号、10号、14号等岩体中发现铜镍矿化.从岩体岩石学及蚀变矿化特征、岩体常量元素、微量元素、稀土元素特征方面进行分析,并与红旗岭镍矿区进行对比,认为其与红旗岭区镁铁-超镁铁岩具同源性,矿床属熔离-贯入型成因,后期热液叠加又是茶尖区独有的成矿特征,通过分析、对比,确定了该区找矿意义和前景区.
The Hongqiling nickel orefield is one of the main concentrated metallogenic regions of magmatic coppernickel sulfide deposits in China.The Chajian ore district is a significant component of the Hongqiling orefield.There occur more than 20 mafic-ultramafic rock bodies in the ore district,in which a few small copper-nickel deposits and mineralized bodies have been found.The characteristics of lithology,alteration and mineralization,macroelements,microelements and rare earth elements are analyzed.By comparisons of the characteristics between Hongqiling and Chajian ore districts,it is concluded that the mafic-ultramafic rocks are affinity,with common deposits of liquationinjection type.The hydrothermal fluid superimposition is the unique ore-forming character in the Chajian ore district.The prospect implications are decided with the analysis and comparison.
