COMPARATIVE ANALYSIS OF CARLIIN-TYPE GOLD DEPOSITS BETWEEN AMERICA AND WESTERN CHINA

The comparative analysis of recent literatures on the metallogenetic dynamics,geological backgrounds and ore forming conditions of Carlin-type gold deposits in both America and China shows a similar metallogenetic geological background,such as the composition of tectonic elements,ancient rift setting,wall-rock alteration,paragenetically associated minerals,element assemblage and maturity of kerogen.The differences are presented in metallogenic epoch,relation to magmatism,occurrence mode of elements etc.The reasons for these differences are also discussed.
