| 摘 要： | 本文在对藏东玉龙斑岩铜矿带花岗斑岩中钾长石斑晶红外光谱与X射线粉末衍射法测定结果的基础上,系统研究了钾长石的红外有序度θ与X射线单斜有序度Sm的对应关系,以及有序度与t_1位Al的占位率和钾长石保持最终结构状态的平衡温度之间的函数关系,并讨论了该成果在火成岩研究中的实用价值。

| Abstract: | On the basis of ordering measurements of K-feldspars from porphyries in the Yulong porphyry copper belt, Eastern Tibet, by X-ray powder diffraction and infrared spectroscopy, the ordering correspondences between the two methods are described in this paper. Also, its relations to Al occupancy and equilibrium temperature are studied. |
