研究了各种变质岩共生矿物中的阳离子分布，利用Sobolev和Ramberg原理解释了不同结构硅酸盐中氧离子极化等晶体能量参数与阳离子分布之间的关系。对低变质级到高变质级岩石的分布系数的统计研究导致了几种地温计和地气压计的制定。该表述应被视为将晶体化学和热力学原理的理论、数据和应用系统化以理解变质和火成过程的尝试。不同温度计和气压计的结果内部一致，并已用于评估变质过程中流体相中 O2、H2O 和 CO2 的分压。变质过程依赖于大地构造过程，因此，变质作用P-规律的研究不能脱离地壳地球动力学演化的研究。
The distribution of cations in coexisting minerals of various metamorphic rocks has been studied, using the principles of Sobolev and Ramberg to explain the relationship between crystal energetic parameters such as polarization of oxygen ions in silicates of differing structures and the distribution of cations. Statistical studies of distribution coefficients in rocks of low to high metamorphic grade have resulted in the formulation of several geothermometers and geobarometers. This formulation should be regarded as an attempt to systematize the theory, data and application of the crystal-chemical and thermodynamic principles to understand metamorphic and igneous processes. The results from the different thermo- and baro-meters are internally consistent and have been used to evaluate partial pressures of O2, H2O, and CO2in the fluid phase in metamorphic processes. The metamorphic processes are dependent on the geotectonic processes and, therefore, the study of theP-Tregimes of metamorphism cannot be separated from the study of the geodynamic evolution of the crust.
