| 中文摘要: |
| 通过对河南汝阳东沟特大型斑岩型钼矿床控矿地质条件及其综合找矿信息的研究,总结以下几点认识:控矿构造不仅是导岩构造,而且也是导矿构造,提供了成矿通道和储矿空间;控矿母岩(成矿母岩)不仅提供了矿质矿液,同时还控制了矿床的空间分布、产状及其规模.高酸、高钾、高碱及低镁(三高一低)的控矿母岩-钾长花岗斑岩为对成矿有利;控矿围岩只要有足够的容矿裂隙皆可成矿,而与围岩的化学性质关系不大.文章同时提出下列综合找矿信息及找矿思路:①确定最佳区域空间位置,②寻找成矿小岩体;③分析围岩蚀变;④重砂中高温矿物异常与水系沉积物元素组合异常的套叠程度是圈定靶区准确程度的关键. |

| THROUGH ANALYZING ORE-CONTROLLING GEOLOGICAL CONDItions of Donggou Mo deposit,It is concluded that ore-controlling structure is not only ore-leading structure,but also rock-leading structure which provides oreforming channel and space.Ore-controlling mother rock(mineralization mother rock) has not only provided mineralization material and fluid,but also controlled distribution,occurrence and scale of ore bodies.Ore-controlling mother rocks are higher in acid and potassium alkalinity,and lower in magnesium,which is favorable for ore-forming.Mineralization can be formed in enough hosting-structures in ore-controlling mother rocks and has no relations with geochemical character of mother rocks.Prospecting indications have been proposed as follows: ascertaining favorable regional location,searching for small ore-forming body,analyzing wallrock alteration,exploring overlapping degree between heavy mineral anomaly and geochemical exploration anomaly. |
