Coupled strontium-calcium isotopes in Archean anorthosites reveal a late start for mantle depletion - Nature Communications High spatial resolution analyses of plagioclase within 3.7–2.8-billion-year-old anorthosites are used to refine strontium isotope models of Earth’s early evolution and imply that large-scale continent...

A new study that looked at isotopes in plagioclase crystals within 3.7 Ga anorthosite rocks suggests that continent formation may have not started until ~3.5 Ga. Could Earth have been mostly a landless ocean world for its first billion years? www.nature.com/articles/s41...
