| 摘 要： | 运用成矿地球化学异常分带指数、因子分析和随机场的理论与方法 ,解析了胶东金矿集中区夏甸金矿的地球化学场结构。指出金成矿作用过程中存在矿化叠加现象 ,矿化因子组合强度直接体现了成矿作用强度。综合成矿元素头晕、主成矿晕和尾晕异常套合的特征 ,指出了找矿方向。在此基础上 ,优选了 6个找矿靶区 ,对深部隐伏盲矿体进行了定位预测。

| Abstract: | The theories and methods of factor analysis and random field were used to resolve the structures of geochemical fields of Xiadian gold ore deposit in Jiaodong gold ore concentrated area, China. The results indicated that the mineralization was piled up during the process of gold ore forming, and the intensity of the ore forming was materialized directly by the combination intensity of mineralization factors. Based on the synthetically research of ore forming element abnormality repeated characteristics of the head halo, main ore forming halo and trail halo, the direction of seeking gold ore bodies was pointed out, the target districts were elected, and the deep stated lied concealed gold ore bodies were prognosticated localizatedly. |
