| 摘 要： | 对采自我国南方燕山期五里亭花岗岩体中的褐帘石,经偏光显徽镜、电子探针仪、差热仪、X射线等方法进行分析得出,该矿物为变生褐帘石。加热800℃,850℃,950℃,970℃,1100℃退火系列样品的X射线粉晶数据分析得出:1.变生褐帘石X射线粉晶分析的最宜加热温度为800-850℃;2.加热至970℃的退火样品,褐帘石已分解为方铈石、赤铁矿、钙长石,加热到1100℃,褐帘石已渐消失,方铈石、钙长石和赤铁矿成为主要矿物相。

| Abstract: | The metamict allanite from South China is studied by using microscopy, DTA and X-ray powder analyses. The results show that the annealed sample heated to 800 ——850(3 gives the standard X-ray data of allanite, and the sample heated over 850℃ is decomposed. The annealed sample heated to 970℃ is decomposed into cerianite, hematite, anorthite and small amount of allanite and other minerals. From the X-ray powder data the reaction process may be expressed as: 2(Ca, Ce)(Fe) . X-ray powder data of the anneaied allanite heated to 11000(2 show that the allanite was decomposed into dominant cerianite, hematite, and anorthite, but allanite disappeared. |
