Deep formation of Earth's earliest continental crust consistent with subduction
About four billion years ago, Earth's outer layer is thought to have been composed mostly of
a 25-to 50-km-thick basaltic crust that differentiated to form the oldest stable continental …

Komatiites reveal a hydrous Archaean deep-mantle reservoir
Archaean komatiites (ultramafic lavas) result from melting under extreme conditions of the
Earth's mantle. Their chemical compositions evoke very high eruption temperatures, up to …

Determination of Fe3+/ΣFe of XANES basaltic glass standards by Mössbauer spectroscopy and its application to the oxidation state of iron in MORB
To improve the accuracy of X-ray absorption near-edge structure (XANES) calibrations for
the Fe 3+/ΣFe ratio in basaltic glasses, we reevaluated the Fe 3+/ΣFe ratios of glasses used …
