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。

Conductivity type of pyrite in deep part of Jiaojia gold deposit in vertical is N type,while the contents of P type pyrite in shallow part are more.From deep to shallow part,ore forming fluid temperature is grad-ually lowered.Mineralization temperature of pyrite in deep part is 400~500 ℃,mineralization temperature of pyrite in shallow part is 150~250 ℃,mineralization temperature of pyrite in middle part is within the scope of these two temperature ranges.It reflects that ore forming fluid temperature is decreasing from deep to shallow during this period.
