Fig. 52. Two closely spaced sections through the Ravn Kløft Member showing the rapid lateral facies changes especially of the fluvial channel deposits. The sections correspond approximately to the interval 255–285 m in Fig. 51A. For legend, see Plate 1; for location, see Fig. 22.

A distinct macroflora (the Ravn Kløft flora) of Middle Albian to Early Cenomanian age was established by Boyd (1998a, b, c, 2000); this flora was broadly contemporaneous with the Upernivik Næs flora of Rosen - krantz (1970). Correlation. The Ravn Kløft Member is laterally equivalent to the Skansen Member in southern and eastern Disko and the older parts of the Kingittoq Member on central and southern Nuussuaq and northern Disko. The Ravn Kløft Member is possibly coeval with the lower part of the Itilli Formation on western Nuussuaq and Svartenhuk Halvø and with parts of the Upernivik Næs Formation on Upernivik Ø (Fig. 16). Kingittoq Member new member History. The Kingittoq Member includes the sediments referred to the Atane Formation on northern Disko, south-eastern Nuussuaq, as well as some of those on northern Nuussuaq. 71
