本文研究了某地含铯榴石伟晶岩的分布规律及特征后,认为铯在伟晶岩浆晚期的富集,是由于挥发组分的集中、岩脉局部膨大、致密围岩的作用等条件而引起的。因此,分异晚期形成的锂云母微斜长石纳长石伟晶岩、岩脉的膨大部位、致密块状围岩是寻找铯榴石的重要标志。 After studying the distribution and characteristics of the pegmatite-bearing pegmatite in a certain area, it is believed that the enrichment of cesium in the late pegmatite is due to the concentration of volatile components, the local dilation of dikes and the action of tight rock. of. Therefore, the late differentiation of the formation of micaceous micaceous plagioclase feldspar pegmatite, dilapidated dikes, dense block rock is looking for an important symbol of pollucite.
