Study on the alteration of Dongping gold orefield, Hebei;
河北东坪金矿田蚀变作用研究
The main alterations are as follows: muscovitization, dolomitization, biotitization, sericitization, chloritization,tourmalinization, greisenization and so on.
这些蚀变作用分别发生于177。
Based on diagnostic spectral characteristics of the ions included in altered minerals and field theory,the authors believe that the alteration occurred in a rock body particle and is closely related to the temperature,pressure and surrounding structure of hydrothermal deposits,and has the field characteristics.
基于蚀变矿物所含有离子或基团的诊断波谱特性和场的理论,对蚀变信息机理研究,认为蚀变作用与热水溶液的温度、压力及周围构造发育情况密切相关而具有场的特征。
