Fig. 1. Geological map <strong>of</strong> southern and central West <strong>Greenland</strong>, showing the divisions <strong>of</strong> the Nagssugtoqidian orogen and the boundaries<br />
with the North Atlantic craton to the south and the Rinkian orogen to the north. Outlined areas indicated A, B and C are, respectively,<br />
the Kangaatsiaq, Agto (Attu) and Ussuit 1:100 000 map sheets. ITZ: Ikertôq thrust zone. NSSZ: Nordre Strømfjord shear zone.<br />
SNO, CNO and NNO are, respectively, the southern, central and northern Nagssugtoqidian orogen. Modified from Escher & Pulvertaft<br />
(1995) and Mengel et al. (1998).<br />
