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_3O_8)和钙长石(CaAl_2Si_2O_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。库多和韦尔(A.M.Kudo和D.F.Weill)首次获得成功,他们于1970年,主要根据花岗岩和钠长石-钙长石二元系的实验资料,用一种经验的方法建立起一个地质温度计,目前已被通称为Kudo-weill斜长石地质温度计。由于这个地
NL Bowen, in his classic account of the melting behavior of plagioclase, proved that the series of NaAlSi 3 O 8 and CaAl 2 Si 2 O 8 formed a continuous solid solution at high temperatures, The model explains its test data. For many years, rock and mineralogy workers have been trying to find out the relationship between plagioclase crystals and liquid constituents coexistent with plagioclase crystallization temperature in the magmatic rocks, based on the experimental study of Bowen’s plagioclase system of 1913 relationship. For the first time, Cuddles and Wells (AMKudo and DFWeill) succeeded in building a geothermal thermometer in 1970 based on experimental data from the granite and albite-to-anorthite binary systems , Is now commonly known as the Kudo-weill plagioclase geothermometer. Because of this place
