一、前言近年来,我们对秦岭某区稀有金属花岗伟晶岩中产出的锂矿物进行了研究,发现该区锂辉石蚀变现象非常普遍。从空间上看,各含锂伟晶岩密集区,不同类型锂伟晶岩,锂伟晶岩中的不同结构带,均有锂辉石的蚀变现象存在;从时间上看,不同阶段产出的各世代锂辉石也都有蚀变现象存在。锂辉石蚀变后,往往变成其它多种矿物集合体,
I. Preface In recent years, we have studied the lithium minerals produced from the rare metal granitic pegmatites in a certain area of Qinling Mountains and found that the spodumene alteration in this area is very common. From the perspective of space, the alteration phenomena of spodumene exist in all the lithium-bearing pegmatite-intensive areas, different types of lithic pegmatites and different structural zones in lithium pegmatite. From the point of view of time, different stages of production The various generations of spodumene also have alteration phenomenon exists. Spodumene alteration, often become a variety of other mineral aggregates,
