摘要
This paper studies the metallogenic features and the mineralization enrichment regularity of copper-silver sulphide diposit. The deposit occurs in the limestone of Maokou Formation and the vicinity of structural fracture belt where the limestone is in contact with basalt in Middle Permian in Ganluo of Sichuan, China. In summary, the authors preliminary believe that the deposit genesis is the filling of copper and polymetallic ore magma. This new copper deposit type has a high grade, is large scale, and accompanies rich beneficial elements. It has a great prospecting potential.
