摘要
测量研究了锆石、黄玉、石榴石、羟硅铍石和符山石的形态和微形貌,并分别列出了这些晶体的化学成分和其它鉴定参数,观察到的生长和溶蚀螺纹证实螺旋生长机制在硅酸盐矿物晶体生长中具有重要意义。
The new data of classical goniometry and DIC microscopic observation are given. The morpholo-gy and surface microtopography of several silicate minerals are discussed, and the growth and dissola-tion spiral, a {100} on the the combination of grossularite, are described. A rather rare crystal draw-ing and DIC pictures of bertrandite show a classical type of 32 classes of symmetry, L2P. The surface spirals observed show the significance of spiral growth mechanism in the development of zircon, visu-vianite and bertrandite etc.
