在地球化学中,微量元素是一个相对概念,通常将自然体系中含量低于0.1%的元素称为微量元素。由于在不同条件下,微量元素的演化规律基本一致,所以可以指示物质的来源和地质体的成因。利用多元统计方法,对新疆吉木乃县罕哲尕能铜金矿区岩石地球化学样品所含微量元素进行相关性分析、聚类分析,以查明以Au为主的微量元素地球化学特征。研究结果显示,研究区Au和As这2种元素活动性强,分异程度高,利于富集成矿,指示研究区在下一步找矿中应以寻找Au金属矿为重点。
In geochemistry, trace elements are a relative concept. Elements that are less than 0.1% in a natural system are usually called trace elements. Due to the consistent evolution of trace elements under different conditions, it can indicate the source of the material and the cause of the geological body. Using multivariate statistical methods, the correlation analysis and cluster analysis of the trace elements contained in the rock geochemical samples of the Hanzhegaon copper-gold deposit in Jimunai County, Xinjiang were carried out to find out the trace element geochemical characteristics of Au-dominated. The results show that the two Au and As elements in the study area are highly motivated and highly differentiated, which is beneficial to the enrichment of mineralization, indicating that the study area should focus on finding Au metal ore in the next prospecting.
