Constraints on Archean crust recycling and the origin of mantle redox variability from the δ44/40Ca–δ18O–fO2 signatures of cratonic eclogites
The nature of the deep calcium geochemical cycle through time is unresolved, in part due to
the dearth of information about the calcium isotope composition of Archean recycled oceanic …
