| Abstract: | Through the exploration in Carlin Trend Gold Belt recently, several super-large gold deposits were descovered at depth in some old mines and in the north-western end of the belt, and the range of the belt was extended. In this paper, the geological characteristics of the super-large gold deposits were discussed. It shows that the host rocks are impure carbonate rock or fine-grained clastic rocks, the mineralisation is related to intermediate-acidic intrusive rocks and Cenozoic volcanic rocks. It is suggested that the metallogenesis of the super-large gold ore deposits are related to the evolution of plate tectonics, and the formation of Carlin trend gold ore deposits are related to rifting. |
