Abstract:

Among the 17 endogenic metallic oredeposits (prospects) in the ChangkengChashan orefield, central Guangdong Province, we selected three deposits, i.e. the Changkeng AuAg deposit, the Hengjiang and the Chashan polymetallic deposits, respectively in the north, middle and south of the orefield, as the examples for the research of metallogenetic zonation. The results show that though the three deposits have different locations, scopes and oreforming elements, they all have the same metallogenetic zonation as Cu→Zn→Pb→Ag→Au from the bottom upwards of an ore body. Further study on the above basis indicates that all the deposits (prospects) as a whole in the orefield surrounding two granite bodies, of which one outcrops and one is concealed, exhibit the same metallogenetic zonation as that of a single deposit. The above findings would be helpful for the exploration in this area.

Key words: metallogenetic zonation, granite, ChangkengChashan orefield, Guangdong Province
