文摘
- •
Crustal xenoliths at Udachnaya pipe include both granulitic lower crust and gneissic upper crust.
- •
Lower crustal samples have a Paleoproterozoic U–Pb zircon age.
- •
Upper crustal samples are Neoarchaean (ca. 2.7 Ga).
- •
The Proterozoic lower crust does not correspond to reworking of the Archaean crust.
- •
The Archaean lithosphere was removed and replaced in the Paleoproterozoic.
