摘要
According to the thermoelectric and thermal decrepitation characteristics of pyrites, the main gold-bearing minerals in the Jiapigou gold ore belt, this paper determines the main metallogenic epoch as well as the mineralization types of each epoch and discusses the possibility of prospecting to the deep. The comprehensive research shows that the mineralization of Jiapigou gold ore belt includes the early high-temperature-epoch and the late medium-low-temperature-epoch. The high-temperature hydrothermal mineralization epoch is the main one. However, mineralization of multi-stage superposition is enhanced.
