因子分析在三岔河找矿预测中的应用

Application of Factor Analysis to Ore Exploration in the Sanchahe Area

因子分析可在许多变量中找出隐藏的具有代表性的因子,将相同本质的变量归入一个因子,可减少变量的数目,还可检测变量间的关系的假设,因此被广泛引用在地质工作中.以云南澜沧三岔河矿区为例,运用因子分析进行找矿方面研究,提取具有代表性的因子,绘制因子得分等值线图.并结合研究区成矿地质条件及已有成矿事实,圈定个找矿靶区为研究地质勘查提供了找矿方向,确定了成矿有利的地段.

Factor analysis can identify hidden factors in a representative number of variables,the nature of thevariables included in a same factor,and reduce the number of variables can also be assumed that the relationshipbetween the variables of detection,it is widely referenced in geological work. Taking Lancang Sanchahe mine areaas an example,the factor analysis was used for prospecting study. We extracted representative factors,and drawedthe factor score contour map. Combining metallogenic geological conditions in the study area and the fact that theexisting mineralization,we delineated a prospecting targets for the study of geological prospecting survey providesdirection to determine the favorable metallogenic area.
