The ore-forming fluids of Yanshanian magmatism evolved from high temperature,high salinity and K-rich fluids via moderate-high temperature and CO2(CH4)rich fluids to moderate-low temperature and low salinity fluids.

• 研究表明,该矿床与燕山期岩浆热液有关的成矿流体,从早期矽卡岩阶段,经中期石英硫化物阶段,至晚期石英方解石阶段,是从高温、高盐度、富钾流体演化至中高温、中高盐度、富CO2(CH4)流体再至中低温、低盐度流体。
