| 摘 要： | 哈佳吉金矿区位于尼罗河大型韧性剪切带次级构造带上，属岩浆热液破碎带蚀变岩型金矿床。该文通过论述矿区地质特征，总结控矿因素，证实该区矿体严格受构造蚀变带控制，近EW向韧性剪切构造，尤其是构造转弯部位、构造膨大部位、不同级别构造复合部位，以及多期成矿作用叠加部位是矿床形成的有利空间。并与岩性和蚀变矿化关系密切，赋存于黄铁矿化碎裂岩、黄铁矿化硅化变粒岩质碎裂岩带中，产状与蚀变矿化带一致。

| Abstract: | Ha Kakichi gold deposit area located in sub - structure belt of large ductile shear belt of Nile river. It belongs to magmatic hydrothermal altered rock type gold deposit. In this paper, through discussing geological characteristics and summarizing ore controlling factors, it is confirmed that this area was controlled by structural alteration strictly. Ductile shear belts with the trend o{ EW, especially the turning areas, swollen parts of the structures, composite parts in different levels of structures, and multi - stage mineralization superimposed parts are beneficial for the formation of deposits. It has close relationship with the lithology, alteration and mineralization, and occurred in pyritized cataclasite, pyritized and silicified cataclastic granulite belt. Its occurrence is consistent with the alteration and mineralization zone. |
