摘要
珍珠的碳酸钙结晶矿物颗粒微小，粒度为１～８ μｍ ，优质珍珠粒度一般为３ μｍ ，因此用一般方法很难鉴别其组构，其结晶轴方位问题始终未得到解决．作者采用Ｘ射线岩组分析研究珍珠内微小矿物的组构，得出结晶Ｃ轴沿径向生长，这为优质珍珠的培育提供了结晶学方向的理论指导．
The crystal shape of calcium carbornate mineral in cultured pearl is false hexagon. The grain size is 1～8 μm. In high quality pearl, the grain size is 3 μm, so it is very difficult to identify its texture. We don′t know the direction of C axis. This paper studied the texture of the small calcium carbornate minerals in pearl with the method of X ray petrofablic analysis for the first time. The results show that C axis is in the direction of radius. We can find crystallography theroy guide when we cultured high quality pearl.
