用聚类分析、因子分析等数学地质方法对红花沟金矿莲花山矿区地表出露石英脉的元素地化特征进行了统计研究，确定了该区元素组合特征和找矿指示元素．提出了“组合元素预测法”，并用该方法对矿区石英脉含矿性进行了评价，取得了较好的地质效果．
By using the methods of cluster analysis and factor analysis, the geochemical characteristics of the quartz veins of the exposed surface of Lianhuashan gold mine in Honghuagou gold mine were studied statistically. The element combination characteristics and ore-prospecting elements were determined. The “combined element prediction method” is put forward and the method is used to evaluate the mineralization of the quartz vein in the mining area, and the better geological effect is achieved.
