Onset of plate tectonics by the Eoarchean
One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Alteration and geochemical patterns in the 3.7–3.8 Ga Isua greenstone belt, West Greenland
Volcanic rocks of the 3.7–3.8 Ga Isua greenstone belt have undergone heterogeneous, poly-
phase post-magmatic alteration, resulting in mobilisation of many elements including LREE …

Silicon isotopes in∼ 3.8 Ga West Greenland rocks as clues to the Eoarchaean supracrustal Si cycle
We report MC-ICP-MS Si-isotopic measurements (δ29Si recalculated as δ30Si) on micro-
subsamples (at 500 μm scale) from several major rock types of the∼ 3.8-Ga-old Isua …

A possible evolutionary origin for the Mn4 cluster of the photosynthetic water oxidation complex from natural MnO2 precipitates in the early ocean
K Sauer, VK Yachandra - Proceedings of the National …, 2002 - National Acad Sciences
The photosynthetic water oxidation complex consists of a cluster of four Mn atoms bridged
by O atoms, associated with Ca2+ and Cl−, and incorporated into protein. The structure is …
