　　区域化探元素致矿序列是通过数理统计的手段，对区域化探样品各元素测试数据的变化系数、样本数、偏度、浓集系数及最低浓集系数等参数进行统计，并以公式定量化的形式得出致矿系数，从而厘定区域化探致矿序列。通过致矿序列的确定，发现在祁漫塔格东段，W、Au、Bi、Sn、Pb、F、Ag、Cd等为该区的主要成矿元素（指示元素）；长城系小庙岩组及印支期侵入岩为W、Sn等的主要找矿靶区；印支期侵入岩与蓟县系、白沙河组、石炭-二叠系等含碳酸盐岩地层的接触部位为Cu、Pb、Zn、Fe等多金属矿产的主要成矿区；Au的主要成矿区则分布在该区中西部的祁漫塔格群地层中，成矿类型应为与白干湖断裂及其次级断裂有关的破碎蚀变岩型。根据区内成矿地质条件及化探组合异常特征，对主要成矿元素的找矿靶区进行了划分。
