Beishan deposit which located on the most north part of yinshan deposit has an independent change trend high to low in ore - forming temperature with from east to west in pace . this indicates that quartz porphyry 5 # may be the mineralization center of beishan deposit 本文通過流體包裹體顯微測溫學研究得出初步結論,北山礦床成礦溫度從東到西呈由高到低的變化趨勢,表明北山的5 #石英斑巖是北山礦床成礦作用的中心。
