DOI: 10.1016/j.epsl.2018.06.030
Abstract: Abstract The transfer of trace elements from external terrestrial reservoirs (i.e. atmosphere, hydrosphere, crust) to the mantle is mainly controlled by their geochemical behaviors during hydrothermal alteration of the oceanic crust and subsequent subduction metamorphism.… read more here.

DOI: 10.1016/j.precamres.2021.106260
Abstract: Abstract The Salma-type Archaean eclogites exposed along the northwestern boundary of the Belomorian Eclogite Province in the eastern Fennoscandian Shield formed as a result of the Mesoarchaean–Neoarchaean subduction and collision. The common protoliths of the… read more here.

DOI: 10.1073/pnas.2210169119
Abstract: We welcome comments on our report of Archean eclogitefacies oceanic crust and deep subduction. However, Zou et al. (1)’s claims concerning our geobarometry and petrography (2) are demonstrably misleading. The garnet-clinopyroxene (Grt-Cpx) geobarometer (3) was… read more here.
