摘要

The study on polyphase fluid inclusions of porphyry copper deposits has always attracted much attention of geologists. In the early 1980s, the chalcopyrite daughter mineral in the fluid inclusions was recorded by a scanning electron microscope in theporphyry copper deposits of West America. However, such a study was poorly reported. In recent years we have studied the Yanyuan porphyry copper deposit in geology and geochemistry. Further study of fluid inclusions with electron microprobe shows the common existence of chalcopyrite daughter mineral in addition to halite in fluid inclusions, suggesting an ore-forming fluid highly enriched in ore-materials such as Cu.
