| 摘 要： | 钾长石是南平伟晶岩中分布广泛的一种造岩矿物，它的结晶作用几乎贯穿于伟晶岩形成－演化过程的所有阶段。通过对不同类型伟晶岩和同一类型伟晶岩中不同世代钾长石的产出条件、物理性质、矿物粉晶X光衍射、化学成分等方面研究，发现钾长石在伟晶岩中的分布有明显的规律性。这不仅深化了对南平伟晶岩形成机制的了解，而且对钾长石的综合利用也有重要意义。

| Abstract: | The potash feldspars is one of important rock forming minerals, which are widely dispersed in Nanping pegmatiees Its crystallization runs through all stages of the pegmatization development The mineral was studied by such means as occurrence condition in different type pegmatites and different generation, chemical composition, X ray powder diffraction, physical character show that K feldspars distribution in pegmatites have obvious regular These studes not only get a deeper understanding for Nanping pegmatization, but also have positive significance to make use of K-feldspars. |
