对诸暨孝四地区加里东期混合岩化变质岩的变质温压条件进行了估算，估算结果显示，孝四地区陈蔡岩群的变质温度约645℃，变质压力约为5.1kbar。提出陈蔡岩群普遍发育的混合岩化现象是减压部分熔融的结果，研究区晚奥陶世到中志留世大规模的地壳抬升是造成陈蔡岩群普遍发育混合岩化的重要原因，很好地解释了陈蔡岩群中普遍发育的混合岩化现象，也对认识华南加里东运动的本质提供了新的视角。

The metamorphic temperature and pressure was estimated for the metamorphic rock undergone migmatization during Caledonian from Zhuji, Xiaosi area. Results show that the metamorphic temperature of Chencai group is about 645℃ and the pressure is about 5.1kbar. We suggest that development migmatization in Chencai group is a result of partial melting to release pressure. Uplift of the Earth's crust in the late Ordovician to Silurian is an important reason for migmatization, which provides a new Perspective to understand the essence of the Caledonian movement in Southern China.
