A shear zone related greenstone belt hosted gold mineralization in the Archean of West Greenland. A petrographic and combined Pb-Pb and Rb-Sr geochronological study

The Late Archean ages for arsenopyrite and garnet are consistent with the regional amphibolite facies metamorphism related to major terrane assemblies in the study area occurring at that time. The ore textures preserved today are interpreted as those formed under this regional metamorphic event.
