摘要
某地变彩斜长石宝石学特征研究指出 ,其产生变彩的原因有 :1光在双晶面上发生的干涉作用 ;2光在出溶结构上发生的干涉作用 ;3光在穿越特殊包体群时发生的干涉与衍射作用。据此可知 。
Based on the study of the gemological characteristics of the plagioclase in certain region,it has been found that play of color is owing to interference on the structure of twin or of exsolution,and differaction on the special inclusions.Therefore,plagioclase of gem quality should be cut along a special direction.
