| 摘 要： | 大河南矿集区处于太行山深断裂带 (岩石圈断裂 )上。有铅锌、金、金银三个远景区 ,具有形成超大型矿床的地质条件 ,显示了超大型矿床的资源前景。矿化受深断裂带及其两侧次级裂隙和各种薄弱面控制 ,与隐伏岩枝、岩脉群、碳酸盐地层、变质地层相关 ,显示地球化学异常。进一步找矿方向 :1)在重要地段勘查深部资源 ;2 )沿岩体接触带找新区。“大调查”工作突破点是 :加强勘查力度 ;加大勘查深度。

| Abstract: | Dahenan metallogenic gathering-area located on Taihangshan mountain deep fractures which are a lithospheric fractures. There are three prospects of lead- zinc, gold and gold-silver deposits in the area that show geological background and prospective reserves of super large-scale deposits. Metallization is controlled by the deeper fractures and of which nearby subsidiary fractures, and various weak zones in the strata. In spatial distribution the orebodies are related to the concealed apophyses, dyke swarm, strata of carbonate rocks and metamorphic rocks. The metallizition set on geochemical anomalies. Further exploration is both prospecting for deeper part of main deposits and discovering new areas along contact zone of two big intrusions in the area. The key work of "China great survey of resource" will be prospect deeper resource and to enhance exploring intensity in the key metllogenic zones. |
