摘要
鲍温(N.L.Bowen)在他的关于斜长石熔融特性的经典论述中曾证明,钠长石(NaAlSi_(3)O_(8))和钙长石(CaAl_(2)Si_(2)O_(8))在高温下形成一个连续的固溶体系列,他按照理想溶液的模式对其试验资料进行了解释。许多年来,岩石、矿物学工作者一直试图以鲍温1913年的斜长石系统的实验研究为基础,找出岩浆岩中斜长石结晶温度与平衡共存的斜长石晶体和液体成分间的关系。
Applying the Kudo-Weill plagioclase geothermometer to basaltic rocks,the author found that the calculated values are generally higher than the measured ones.This paper offers,an empirical refinement of the Kudo-Weill plagioclase geothermometer based on experimental data of natural basaltic rocks and Ab-An-Di system.Being applied to basaltic rocks or basaltoid rocks of dry system,the refined plagioclase geothermometer can give more realistic and accurate estimates on the crystallization temperature of plagioclases.
