摘　　要：本文通过岩浆体系的温度－水逸度及岩石熔融曲线关系、岩浆岩典型矿物组合、矿物成分等与物理化学条件的相互关系，确定了月山地区闪长岩类岩浆结晶的水逸度、水压、定位压力和深度以及温度、氧逸度和氢逸度，构筑了区域侵入岩的Ｔ－ｆｏ２图解，并讨论了岩浆结晶的物理化学条件与成矿作用的联系．Based on the relationships among temperature,water fugncity and rock meltingcurves of the mngmatic system, the typical mineral associations of the msgnatic intrusions,and the relationship between the mineral chemical compositions and the physicochemical conditions,this Paper bas precisely calculated the water fugacity and pressure, the magmatic emplacementpressure and depth, and the temperature,oxygen fugacity and hydrogen fugacity of the crystallizing dioritic magmas in Yueshan area.The T-fo2 diagram of the dioritic intrusions is constructed.The relationship between the magmatic crystallizing physicochemical conditions and the coppermetallogenesis is also discussed.
