中文摘要：
以红旗岭铜镍硫化物矿床茶尖矿区1号和9号岩体为研究对象,进行了岩石化学特征分析、微量元素分析和稀土元素（REE）分析,重点研究了其铂族元素（PGE）地球化学特征。REE分析结果表明,岩石富集轻稀土元素,且有微弱的铕负异常。PGE富集在硫化物含量高的岩石中,与硫化物含量呈正相关关系。岩石中PGE分异明显,富集Rh、Pt和Pd。推测该区的基性-超基性岩形成于硫不饱和玄武质岩浆的演化,岩浆有地壳物质混染的特征,其成矿物质来源于上地幔,主要成矿机制为深部熔离-贯入作用。
英文摘要：
Using the 1st and the 9th mafic intrusions of the Chajian ore district in the Hongqiling copper-nickel deposit as the research objects,we analyzed their petrochemical characteristics,trace elements and rare earth elements（REE）,especially the geochemical characteristics of platinum group elements（PGE）.The analysis of REE shows that the rocks are enriched in light REE and have weak negative europium（Eu） anomalies.PGE are concentrated in the rocks with high sulphide content,and the PGE content and the content of sulfide are positively related.The fractionation of PGE is obviously featured by enrichment of Rh,Pt and Pd.We supposed that the basic-ultrabasic rocks were formed under sulphur undersaturated conditions,from basaltic magma contaminated by crustal materials.The source of ore-forming materials of Chajian ore district is from the upper mantle and the main mechanism is deep liquation and injection.
