焦家金矿垂向上深部矿体黄铁矿导型以N型为主,矿体浅部P型黄铁矿含量较多;从深部到浅部成矿流体的温度在逐渐降低。矿体深部黄铁矿成矿温度集中范围在400~500℃,浅部的黄铁矿成矿温度主要集中在150~250℃,中部的黄铁矿成矿温度则在这两个温度范围之间,反映在成矿过程中,从深部到浅部成矿流体的温度在逐渐降低。
In Jiajiao gold deposit, the type of pyrite in the deep ore body is mainly N type in the vertical direction, while the P type pyrite content in the shallow part of the ore body is relatively high. The temperature of ore-forming fluid from deep to shallow part is gradually decreased. The mineralization temperature of deep pyrite in the ore body ranges from 400 ℃ to 500 ℃. The mineralization temperature of pyrite in shallow part mainly concentrates at 150 ~ 250 ℃, and the mineralization temperature of pyrite in the middle part is in these two temperature ranges Between the reflection of the mineralization process, the temperature of the ore-forming fluid gradually decreases from deep to shallow.
