在地表风化条件下铍的转移性很弱。在现代沉积物形成的过程中,铍由于有很高的离子位能,能够存在于原生矿床附近的分散系统和胶体系统中。因此,铍的分散晕在铍矿床发育地区的第四纪沉积中将是很小的,只要是铍含量高于克拉克值就明显地指明它的原生产地。为了检查上述推断,选择了位于森林区中的被很厚浮土复盖的含铍伟晶岩发育地区。伟晶岩中有用组份含量比较低由于在地表风化条件下主要铍矿
Beryllium is poorly transferable under surface weathering conditions. During the formation of modern sediments, beryllium can exist in dispersed systems and colloidal systems near primary deposits due to its high ionic potential. Therefore, the dispersion of beryllium will be very small in the Quaternary sediments of the beryllium deposit area. As long as the beryllium content is higher than the Clarke value, it clearly indicates its original place of production. In order to examine the above inference, the area containing beryllium pegmatite, which is covered in very thick earth, is located in the forest area. The pegmatite has a lower content of useful components due to the main beryllium ore under surface weathering conditions
