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 …

The petrogenesis of ultramafic rocks in the> 3.7 Ga Isua supracrustal belt, southern West Greenland: Geochemical evidence for two distinct magmatic cumulate trends
Ultramafic rocks with MgO> 25 wt.% are found as large slivers within the Eoarchaean Isua
supracrustal belt. Some of these ultramafic bodies have previously been proposed to …
