众所周知,微量水对矿物和熔体的物理性质会产生重大影响:强度和粘度降低,扩散速率和电导率增大,地震波衰减,固相线由于水的加入而降低等.这种广泛的影响无所不在,使得水成为所有地质体系中最活泼的成分,可用以解释整个地球的演化和动力学.水的PVT关系是其基本的物理化学性质.在冰-水相平衡系统中,水的P-T稳定范围由熔化压力线范围限定,沿着这条曲线,水与冰的各种变体处于平衡.水和其它固体样品不同,必须就位测量其物理化学性质,这就增大了实验测量的难度.尽管水在地质上很重要,有
It is well-known that trace amounts of water have a significant effect on the physical properties of minerals and melts: reduced strength and viscosity, increased diffusion rate and conductivity, seismic attenuation, attenuation of solidus due to the addition of water, etc. This wide range of effects is widespread , Making water the most active component of all geological systems and can be used to explain the evolution and dynamics of the entire earth. The PVT relationship of water is its basic physicochemical properties. In the ice-water phase equilibrium system, the water PT stability range It is defined by the range of melting pressure lines along which water and ice are balanced, and water, unlike other solid samples, must be measured in place for its physicochemical properties, increasing the difficulty of experimental measurements. Although water is very important in geology, there is
