斜长石的有序度取决于结晶时的热力条件及其后来的热力变化。但是,在地质测温中有序度的运用,由于动力因素的影响使问题复杂化。因此,只有当动力因素不具决定作用时,研究某些矿物生成过程中斜长石的结构状态才有意义。中-高温变质作用可归于这种过程。 低温斜长石的结构状态不能灵敏地反应其形成时的热力条件,因为当温度低于400℃时达到有序度平
The degree of order of plagioclase depends on the thermal conditions during crystallization and its subsequent thermal changes. However, the use of orderly degree in geological temperature measurement complicates the issue due to the influence of dynamic factors. Therefore, it is only meaningful to study the structural state of plagioclase in some mineral formation only when the dynamic factors are not decisive. Medium-high temperature metamorphism can be attributed to this process. The structural state of the low-temperature plagioclase does not respond sensitively to the thermal conditions at the time of its formation because the order of degree is reached when the temperature is below 400 ° C
