铸石中辉石枝晶生长与形貌研究

RESEARCH ON THE CRYSTAL GROWTH AND MORPHOLOGY OF PYROXENE DENDRITES IN CASTSTONE

本文介绍了铸石的性能和应用，以及铸石制品的生产过程。对样品进行了各方面测试分析。铸石中辉石枝晶具有奇特的分枝形貌。通过光学显微镜和扫描电镜观察，较详细地分析了辉石枝晶的形貌细节。辉石枝晶一般发育三级分枝，各分枝间彼此以９０°和１１０°交角沿单斜辉石类型的结晶轴方位生长。岩浆熔体的性质和生产工艺深刻影响着辉石枝晶生长演变。

The properties and application of caststone,and the productive process of caststone are introduced in this paper.Many aspests of sample are measured or analyzed.Pyroxene dendrite in caststone are commonly with a peculiar dendritic morphology.Bascd on the studies of morphological details by OM and SEM,it is clearly showing that the dendrites generally developed three order braches,the angles between them are about 90° or 110° .Branches priorly grow along with clinopyroxene crystal axis.The property of magma melt and producing technology are profoundly influence on the growth and development of pyroxene dendrite.
