摘要
因子分析是研究元素共生组合的一种有效的方法,其中的每一个因子都表示一种元素之间的组合关系,这种组合关系的研究对于成矿预测有很大的帮助。这里对青海省南部治多-杂多地区的地球化学数据中的十七种元素进行R型因子分析,得出了五个因子,分别代表了不同的元素组合特征。将各个因子所对应的因子得分绘制成等值线图,与实际地质背景相结合进行成矿有利分析,可为成矿预测提供线索和依据。
The factor analysis is an effective method to study the symbiotic combination of elements,and each of these factors indicated that a relationship of combination among elements.So,when people study the mineralization or the metallogenic prediction,they can get some clues from the relationship.In this paper,the author collected the geochemical data of zhiduo-zaduo region in southern Qinghai province,and selected 17 elements to do R-factor analysis.Then,the author get 5 different factors indicating the combination features of several elements,and drawing the contour maps based of factors scores.The next important thing is the analysis of factors with the actual geological background of favorable ore-forming.Moreover,the author hope that this results of the analysis can provide clues and basis for metallogenic prediction.
