“…For the Inglefield Orogen, we do not find evidence for a dissected eastward extension from Inglefield Land (∼78.5°N, 68°W) across to northeastern Greenland, but rather multiple high-confidence geophysical boundaries at ∼50°W. Following D09 and Nutman et al (2019), we distinguish the Victoria Fjord Terrane exposed at the head of Victoria Fjord (∼81.6°N, 45.5°W) from the younger Rae Craton. For this terrane, we find some geophysical evidence for narrower eastern and western subglacial extensions and a more southerly extension from Victoria Fjord.…”

Present understanding of Greenland's subglacial geology is derived mostly from interpolation of geologic mapping of its ice‐free margins and unconstrained by geophysical data. Here we refine the extent of its geologic provinces by synthesizing geophysical constraints on subglacial geology from seismic, gravity, magnetic and topographic data. North of 72°N, no province clearly extends across the whole island, leaving three distinct subglacial regions yet to be reconciled with margin geology. Geophysically coherent anomalies and apparent province boundaries are adjacent to the onset of faster ice flow at both Petermann Glacier and the Northeast Greenland Ice Stream. Separately, based on their subaerial expression, dozens of unusually long, straight and sub‐parallel subglacial valleys cross Greenland's interior and are not yet resolved by current syntheses of its subglacial topography.

Ordovician strata in Greenland are extensively exposed in North Greenland and northern East Greenland; additional small traces (loose blocks) are recorded from the craton of West Greenland. The western North Greenland succession, is nearly identical to that of the Franklinian basin exposed in Ellesmere Island, Arctic Canada; the eastern North Greenland represents the (present) northeastern corner of Laurentia and provides the connection to the East Greenland Caledonian platform. The northern East Greenland succession is the natural northern extension of the Caledonian platform of northern Europe and the Appalachian platform of eastern North America. During the Ordovician Greenland occupied a palaeogeographical subtropical to tropical position with a faunal assemblage typical of Laurentia. A prominent faunal peak of diversification occurred in the Late Ordovician. The stratigraphical succession of Greenland is summarized and age relationships are discussed with reference to the fossil faunas and breaks in the sequences and correlation between the locations and regions are provided.
