Description
Summary:The Nagssugtoqidian orogen and its transition into the Rinkian orogen to the north were the main focus of the field activities of the Geological Survey of Denmark and Greenland (GEUS) in West Greenland in the summer of 2001. This work was carried out within the framework of the Survey’s three-year programme of bedrock mapping and mineral resource evaluation to enhance the understanding of the Archaean and Palaeoprotero-zoic crustal evolution in the transition zone between the Nagssugtoqidian and Rinkian orogens (Fig. 1). The work in the field season of 2001 comprised geological mapping of the 1:100 000 Kangaatsiaq map sheet described in this paper (Fig. 2), an investigation of the supracrustal rocks at Naternaq / Lersletten (Østergaard et al. 2002, this volume), a geochronological recon-naissance of the southern Rinkian orogen in the north-ern Disko Bugt region (Garde et al. 2002, this volume), a resource evaluation of the Nagssugtoqidian orogen (Stendal et al. 2002, this volume), a synthesis and inter-pretation of geophysical data of the central part of the Nagssugtoqidian orogen (Nielsen et al. 2002, this volume) and a report on investigations of the kimber-lites and related intrusive rocks in the southern Nagssugtoqidian orogen and its foreland (Jensen et al. 2002, this volume). The present investigations build on recent previous activities in the region. The Disko Bugt project of the former Geological Survey of Greenland investigated the geology and evaluated the resource potential of the southern part of the Rinkian orogen between
