Zircon trace element and O-Hf isotope analyses of mineralized intrusions from El teniente ore deposit, chilean andes: Constraints on the source and magmatic evolution of porphyry Cu-Mo related magmas
Intrusive rocks related to porphyry copper mineralization are part of the wide diversity of subduction-related, mantle-derived, igneous rocks generated in convergent margin settings. What differentiates them from barren igneous rocks results ultimately from the multi-component and multi-stage processes that condition magma composition in these settings. Unfortunately, the petrogenetic history is largely obscured by the pervasive alteration that affects rocks in these deposits. We address this...[Show more]
