摘要
对尼勒克尼新塔格铁矿岩(矿)石进行主量元素、稀土元素和微量元素等的测试(X荧光法、全谱直读光谱法、ICP-MS法)表明,矿体和围岩富集轻稀土元素及大离子亲石元素,高场强元素相对亏损。铁矿形成的构造环境是与钙碱性火山岩密切相关的陆缘火山弧,成矿作用以火山喷流沉积为主。
ThispaperstudiedofNixintageirondepositwithsystematicgeochemicalmethods.WithtestanalysisofNixintage iron deposit on major elements,rare-earth element and trace element,such as X fluorescence,direct reading spectrograph and ICP-MS,it indicated that the ore body and wall rock are enriched in light rare-earth elements and LILE,and depleted in HFSE. The tectonic environment of this iron deposit is volcanic continental margin volcanic arc which is closely related to calc-alkaline volcanic rocks.Mineralization of iron deposit is dominated by volcanic pour-deposition.
