摘要
矿床赋存于全新统冲积层。蓝宝石具有呈蓝色、粒度大、透明、瑕疵较少、加工性能良好的特征 ,虽与全球高档蓝宝石 (A级品 )相比略差 ,但比国内所产的蓝宝石高一个档次 ,该区且有找A级品的条件 ,具有一定的开发价值。
This saphire deposit is occurred in the Holocene alluvium. The saphire is characterized by blue colour, coarse grain, good transparency, less flaw and easy processing. Its quality is higher by one grade than that in China. And it is possible to find out the saphire with grade A in this ore-field.
