Abstract The Archean craton of West Greenland consists of many fault-bounded Eoarchean
to Neoarchean tectonic terranes (crustal blocks). These tectonic terranes are composed …

Pseudosection modelling is rapidly becoming an essential part of a petrologist's toolkit and
often forms the basis of interpreting the tectonothermal evolution of a rock sample, outcrop …

Many geological and geochemical changes are recorded on Earth between 3 and 2 Ga.
Among the more important of these are the following:(1) increasing proportion of basalts with …

The 700 km-long North Atlantic Craton (NAC) in West Greenland is arguably the best
exposed and most continuous section of Eo-to Neoarchaean crust on Earth. This allows a …

Apatite is a useful geochronological tool due to its common occurrence and incorporation of
a variety of radioactive parent isotopes during crystallisation. However, an understanding of …

Deformation in shear zones is difficult to date because mylonites can preserve partially reset
pre-existing isotopic signatures. However, mylonites can be key structural elements in …

This paper investigates the petrogenesis of the Seqi Ultramafic Complex, which covers a
total area of approximately 0.5 km 2. The ultramafic rocks are hosted by tonalitic orthogneiss …

Different geodynamic models exist for the growth and differentiation of Archean continental
crust, ranging from horizontal tectonics with subduction zones to vertical tectonics with …

Corundum (ruby-sapphire) is known to have formed in situ within Archean metamorphic
rocks at several localities in the North Atlantic Craton of Greenland. Here we present two …

The beginning of modern–style plate tectonics on Earth is not a consensus, but many
authors suggest that it happened transitionally, from 3.2 to 2.5 Ga. In the Amazonian Craton …
