It was formed by crustal accretion onto the Saamian (3.1–2.9 Ga) nucleus during the Lopian (2.9–2.6 Ga), Svecofennian (1.9–1.8 Ga) and Gothian (1.7–1.5 Ga) orogenies. The Sveconorwegian orogeny was mainly a period of late Proterozoic小平面 发表于 2025-3-23 21:16:27

From the results of experimental and geochemical studies, it is clear that basaltic magmas can be regarded as first-order differentiation products of mantle melting, hence they (and komatiitic magmas) play an important role as probes of chem教育学 发表于 2025-3-24 01:10:31
