摘要
在矿物变化研究工作中,配接有 X 射线能谱仪的扫描电镜,能直接观察矿物变化过程中所发生的微观现象和新形成矿物的特点,并且可以同时确定其化学元素组分及相对含量变化。本文着重介绍长石在不同环境条件下,变化形成高岭石、多水高岭石、水云母及水云母—蒙脱石过渡型矿物的微观进程,并作了一些分析探讨。
The SEM with EDX plays an important role in study of mineral changes Use of SEM allows direct observation of microforms in mmeral change and characteristics of newly formed minerals.At the same time,it can be used to determine their element composition.The results are of great importance in inter pretation of the conditions and the mechanism for mineral changes.In this paper the application of SEM type KAD-1000B to study of feldspar trans formation is discussed.Under different conditions the feldspar transformed into kaolinite,hal- loysite,illite,and illite-montmor illonite miner als of transitional type study on mineral change- by SEM is a new way for development of petrology and mineralogy.
