文摘
- •
Mesozoic Zijinshan magmatism occurred in two periods and can be further divided into three magmatic events.
- •
Ore-bearing magmas are characterized by higher ƒO2 than the barren magmas.
- •
Both barren and mineralized magmas have no adakitic affinities.
- •
The changes of the tectonic setting may result in the different sources for the magmatic and mineralization event.
