| 摘 要： | 在综合信息矿产预测理论与方法指导下,以金矿床密集区为模型单元,金异常密集区为预测单元,在GIS平台上开展综合信息矿产预测.结果表明,陕南地区大型金矿床的控矿因素具有共生和伴生的特点,可作为同一成矿母体.本地区的超大型金矿床大都分布在前寒武纪出露和隐伏基底边缘,中酸性岩体边缘和项部,双层结构控制的古生代盖层的泥盆系地层以及重磁环线构造的交汇处等.

| Abstract: | Under guidance of the general theory and method of mineral resources appraisal on synthetic information, taken Au deposit concentrated regions as model units and Au anomaly concentrated regions as prediction units, the mineral appraisal of gold deposits on synthetic information is carried out on GIS platform. It was discovered that the ore control factors of the large Au deposits has both paragenetic and associated characters in southern Shaanxi Province, and they can be regarded as the same metallogenic "matrix". In southern Shaanxi Province, large Au deposits are mostly distributed at the following sites: the margin of the exposed and conceal basements,at the top or the edge of intermediate acid intrusions, and the Devonian strata in the Paleozoic cover controlled by the double structures, and the intersecting parts of the circulars and lines of gravity and magnetic structures. |
