Geology and Ore Depositions in the Area of the Chin-qua-shih Mine(3)

Zonal Mineralization

Abstract

Chin-qua-shih Mine (Cu, Au, Ag), Kufun Mine (Au, Ag) and Butan Mine (Au, Ag) are located close to each other in the northeastern part of Taiwan, and each mine shows different stages of ore mineralization as follows :
In these mines, vertical and horizontal distribution of gangue and ore minerals show zoning which seems to have been formed by repetition of different units in the course of mineralization.
