Geology of Porphyry Copper Deposits

In this talk I will focus on the porphyry and IOCG deposits which develop at a slightly shallower depth that the mafic layered complexes, generally in the range of 4 or 5 to 1 km depth. Porphyry deposits and IOCGs are the worlds primary source of copper and they account for more than 60% of the copper production globally but in addition to copper they also supply 100% of the worlds molybdenum

4. Mineral systems approach to porphyry CuAu

4.1. The mineral systems approach. This study adopted a mineral systems approach to help constrain the work flow of this prospectivity analysis. The mineral systems approach is based on the premise that mineral deposits are the focal points of much larger earth process systems that operate on a variety of scales to focus mass and energy flux.

Porphyry an overview ScienceDirect Topics

Indeed, there are many porphyry systems that are not associated with convergent margins. For example, the 1018 Ma Gangdese porphyry Cu belt and the 3352 Ma Yulong porphyry Cu, both in Tibet, are not linked to subduction zones (Hou et al., 2003, 2004). Instead they are related to postcollisional extensional tectonism and NS trending
