阴极发光(CL)技术在我国主要被运用于石油研究领域。而将CL应用于矿床学研究等方面,国内仍不普遍。通过对黔东南黎平-古邦区碎屑岩中硅质矿物阴极发光特征研究发现硅质来源不同,且有多期次,仅部分硅质与金成矿来源有较直接关系。该区热液硅化石英的愈合裂隙及缓慢的结晶过程给金的聚集提供了良好的运输通道和储存空间。
Cathodoluminescence (CL) technology is mainly used in petroleum research field in our country. However, the application of CL in deposit study, etc., is still not widespread. Based on the study of the cathodoluminescence characteristics of siliceous minerals in the clastic rocks in the Liping-Kupang area of Southeast Guizhou, it is found that the sources of the siliceous minerals are different and have multiple periods. Only a part of the siliceous materials is directly related to the gold mineralization source. The healing fissures and slow crystallization of hydrothermal silicified quartz in this area provide a good transport channel and storage space for the gold to accumulate.
