摘要
以490中段为例,根据硫同位素平衡温度、包裹体均一温度以及矿物温度确定主要成矿期各个阶段的温度范围:矽卡岩阶段温度为300~580℃,云英岩阶段温度为226~489℃,高—中温硫化物阶段温度为246~350℃,中—低温硫化物阶段温度为158~270℃。
This paper researched Mineralization temperature of Shizhuyuan deposit aimed at 490 middle zone. Temperature boundaries of mineral sequences in main metallogenic epochs are ifxed based on sulfur isotope equilibrium temperature,inclusions homogenization temperature and mineral temperature:the temperature of skarn stage ranges 300~580℃,quartz and mica stage ranges 226~489℃,high and medium temperature sulifde stage ranges 246~350℃,medium and low temperature sulifde stage ranges 158~270℃.
