Continental velocity through Precambrian times: The link to magmatism, crustal accretion and episodes of global cooling
Quasi-integrity of continental crust between Mid-Archaean and Ediacaran times is demonstrated by conformity of palaeomagnetic poles to near-static positions between ∼2.7–2.2 Ga, ∼1.5–1.2 Ga and ∼0.75–0.6 Ga. Intervening data accord to coherent APW loops turning at “hairpins” focused near a continent...
