N2 - During the 2013 field season, siliciclastic and carbonate rocks of the
lower Palaeozoic sedimentary succession of the Franklinian Basin in
Amundsen Land, central North Greenland, were collected for whole-rock
geochemical analysis. These data are evaluated here in an attempt to
identify possible hydrothermal signatures related to sediment-hosted
Zn-Pb mineralisation, similar to that found in correlative strata at the
large Citronen Fjord deposit located c. 100 km to the
eastnorth-east. In this paper, we use the term Sedex in a broad sense to
describe stratiform, sediment-hosted deposits that formed either by
syngenetic (exhalative) processes or by subsea-floor replacement coeval
with sedimentation (e.g. Emsbo et al. 2016); the term
Mississippi Valley-type (MVT) is used for non-stratiform Zn-Pb deposits
that formed epigenetically during late diagenesis or tectonism (e.g.
Leach et al. 2010).
