We conclude that the magmatism-mineraliztion of the Zijinshan ore-field was mainly controlled by the multiple activation of the NW-trending Shanghang-Yunxiao deep fault in response to Pacific plate subduction. There occurred a small scale of the magmatism and metallogenesis in the Zijinshan ore-...
These discoveries provided a more compelling mechanism for continental drift, and helped to validate Wegener's theory. Today, the theory of continental drift is an established part of geology, and is known as plate tectonics. The movement of the continents is thought to be driven by the ...
