BIKOU Group comprises spilite and keratophyre, which are lower-grade (greenschist facies) metamorphosed and interbedded by main basic rocks at the bottom and acid rocks on the top. Some copper deposits and ore spots such as Damaoping, Faziba and Yangba have been found in spilite stratum. Becauseresearches have not been well carried out on geology of these ore deposits, some basic problems concerning ore source, characteristics of ore-forming fluid and mineralization age, etc. remain unsolved. Thispaper mainly discusses the mineralization mechanism and mineralization age.
