一九七二年是矿物学家们感到稀有的又一个年头,仅有几项贡献可以举述。这里所用的“矿物学”一词实为最广义的用法,它把岩石学,地球化学和结晶学叠加在一起。 一九七二年召开了一次长石会议。电子光学研究解决了斜长石的某些疑难问题。并提出了一些新的问题。晕色拉长石看来是两种斜长石组成的,这两种斜长石的区别在于相差约10％的钙长石(An)。倍长石中的’Huttenlocher’共生体是由钙长石和拉长石组成的。由一个或两个组分构成的原始钙长石的结
Another year that mineralologists felt rare in 1972 was only a few contributions. The term “mineralogy” is used here in its broadest sense, superimposing petrology, geochemistry and crystallography. In1972, a feldspar meeting was held. Electro-optical research has solved some of the difficult problems of plagioclase. And put forward some new problems. Haloid Labradorite appears to be composed of two types of plagioclase, the difference between the two types of plagioclase lies in the difference of about 10% of anorthite (An). The “Huttenlocher” symbiont in palygorskite is composed of anorthite and labradorite. The original anorthite knot made up of one or two components
