Abstract:
      The Naruo copper(gold) deposit is a comparative typical porphyry deposit and an important part of Duolong ore-concentration area, located Bangonghu-Nujiang suture. The mother rock is granodiorite porphyry rock, and ore body exists in granodiorite porphyry rock and alteration feldspathic quartz sandstone, while most of the ore body consists of the alteration feldspathic quartz sandstone. The copper orebody includes a large amount of cryptoexplosion breccias, and brecciate includes alteration feldspathic quartz sandstone and minor magma breccias. A large amount of magmatic hydrothermal has happened in Naruo deposit, and magmatite mainly exists in the form of tock and dyke, which indicates strong mineralization conditions. Stratum, fault and igneous rock are main Ore-controlling factors.There are obvious prospecting guides, such as rocks, geochemical exploration and rock alteration.
