Hypogene enrichment in Miduk porphyry copper ore deposit, Iran. [PDF]

open access: yesSci Rep, 2022
AbstractThis study was planned with the aim of identifying the nature and circumstances of the high-graded central core and increasing trend of copper content through depth of 1000 m in Miduk PCD. Mechanisms of high-grading, refer to hypogene enrichment (HE), in PCDs poorly understood.

A zircon case for super-wet arc magmas [PDF]

open access: yesNature Communications
Arc magmas have higher water contents (2-6 wt.% H2O) than magmas generated in other tectonic environments, with a growing body of evidence suggesting that some deep arc magmas may be ‘super-wet’ (>6 wt.% H2O). Here, we use thermodynamic modelling to show
