在亚洲北东部形成的金-银、金-石英、金-锑和金-稀有金属的改造型矿床与多旅回构造-岩浆活动的广泛发育过程有着密切的关系.这种构造-岩浆活动导致了火山边缘带Urnotsk-Chukotka火山岩带的形成. 第1类矿床的形成是由于来自金-硫化物建造的最早的浸染状矿石再改造的结果;第2类矿床的形成是由于来自围岩的矿石矿物多次再改造的结果.第1类矿床与侵入-穹隆构造有关;而后者的形成是由于火山边缘带内冒地槽岩块遭受构造-岩浆活动影响的结果所致.
The altered deposits of gold-silver, gold-quartz, gold-antimony and gold-rare metal formed in the NE Asia are closely related to the extensive development of the magmatic activity of the Multi-Brilliance tectono-magmatic activity Formation of the Urnotsk-Chukotka volcanic belt on the marginal zone of the volcano.The formation of the Type 1 deposits was due to the remodeling of the earliest disseminated ore from the gold-sulphide formation; the formation of the Type 2 deposits was due to the ore from the surrounding rock The result of multiple re-alterations of minerals is that the first type of deposit is related to the intrusion-vault structure, and the latter is formed as a result of the tectono-magmatic activity of the braided blocks in the marginal zone of the volcano.
