一、花岗岩形成的物理化学条件 1、温度估计晒字和红石头岩体二长花岗岩的熔化实验结果见表37。表中可见,在2Kb的压力条件下,初熔温度为720℃。施性明等对“玲珑花岗岩”和郭家岭花岗岩的熔化实验结果比晒字和红石头花岗岩低,在2Kb的压力条件下,初熔温度是600—650℃。需要指出, First, the formation of the physical and chemical conditions of granite 1, the temperature estimated sun word and red rock granite melting experiment results in Table 37. It can be seen from the table that the initial melting temperature is 720 ° C under the pressure of 2Kb. Shi Xiaoming and other “Delicate Granite” and Guojialing granite melting test results lower than the word and red rock granite, at 2Kb pressure conditions, the initial melting temperature is 600-650 ℃. Need to point out,
