Abstract: Zircon geochronology provides critical information on the rates and durations of geological processes and enables researchers to explore deep time. However, some zircon datasets show a continuum of concordant ages (‘smear’) without well‐defined age populations.… read more here.

Abstract: Melt migration through Earth's crust drives well‐documented melt–rock reactions, locally changing rock assemblage and geochemistry. However, melt–zircon interaction remains understudied. We report on three zircon‐melt interaction events from the Pembroke Granulite, New Zealand. Primary zircon… read more here.

DOI: 10.3390/min15030214
Abstract: Copper is a critical metal required for green energy technologies such as wind turbines and solar cells. However, copper supply is limited by copper recovery from primary copper sulphides (e.g., chalcopyrite-CuFeS2) due to passivating reaction… read more here.
