Archaean andesite petrogenesis : insights from the Grædefjord Supracrustal Belt, southern West Greenland
We present new whole-rock major, trace and platinum-group element data, as well as Sm–Nd and Lu–Hfisotope data for meta-volcanic rocks from the Mesoarchaean Grædefjord Supracrustal Belt (GSB), locatedwithin the Tasiusarsuaq terrane, southern West Greenland. We also present new in situ zircon U–Pbisotope data (by LA-ICP-MS) for associated felsic rocks. This region has experienced amphibolite to low
