The Paleoproterozoic Sokoman Formation (ca. 1.88 Ga) of the Labrador Trough, eastern Canada, is a ca. 100-m-thick succession of interbedded iron formation and fine-grained, terrigenous clastic sedimentary rocks.Detailed examination of drill cores and outcrops indicates a dynamic paleoshelf where an oxygen-stratified water column, coastal upwelling of hydrothermally derived Fe and Si, as …

Labrador is the ring of Aphebian sedimentary and volcanic rocks surrounding the Superior Province (Fig. 1). Erosional remnants of the Circum-Ungava Geosyncline in the Belcher Fold Belt, the Cape Smith Belt and the Labrador Trough encircle the Archean gneisses of the Ungava Craton on the west, north, and east, re-spectively (Dimroth et al. 1970).
