Review of Survey Activities 2005: Using zircon geochronology to resolve the Archaean geology of southern West Greenland

In summary, petrographic, whole-rock geochemistry and Nd data, and detrital zircon geochronology indicate that felsic to intermediate Rhyacian rocks of the São Luís cratonic

and zircon geochronology of paleoproterozoic granitoids: further evidence on the magmatic and crustal evolution of the São Luís cratonic fragment, Brazil. Geochronology, Nd

Maniitsoq and the small island west of Manertooq ( A ) still preserve intrusive contacts of (?) Archaean granodiorite and tonalite into the supracrustal rocks, whereas the intensity

The geophysical model for the floor of the intrusion has the same dip as the regional strata of 10–20°S but also shows a dip of around 15° towards the east that is unexpected from

In 2004 the Geological Survey of Denmark and Greenland (GEUS) initiated a study of the origin and tectono-meta- morphic evolution of greenstone belts and important regio- nal

However, farther south, in the central part of the Nagssugtoqidian orogen, Palaeoproterozoic granulite facies metamorphism has led to U loss in Archaean rocks, resulting in

This paper describes a detailed structural investigation of lineament zones and the establishment of an event succession for fault and fracture zone evolution in central parts of
