“…2, 5, 10) is dominated by shallow-marine sediments, deposited during a period characterized by reduced terrigeneous clastic influx and several stratigraphic breaks. The Wilhelmøya Subgroup is succeeded by the basal beds of the Janusfjellet Subgroup, showing initiation and advance of the major Bathonian-Callovian transgression in the area (Bäckström & Nagy 1985;Nagy et al 1990) disrupted by a mid-Callovian regressive phase (Smelror, pers. comm.…”

This is reflected by dark grey shales (the paper shales of the Slottsmøya Formation), highly enriched in trace elements such as V, Ni, U and Cr (Dypvik 1980;Nagy et al 1988Nagy et al , 1990. In contrast, the time-equivalent North Greenland successions display higher sand content, lighter colours and a lower organic content.…”

We present sedimentological comparisons and stratigraphical correlations of the Jurassic and Cretaceous epicontinental shelf deposits of Svalbard and updated descriptions of the shallow‐marine North Greenland sediments of East Peary Land and Kronprins Christians Land (Kilen). The Callovian to Volgian Agardhfjellet Formation of Svalbard is correlated to the lower part of the Ladegårdsåen Formation on East Peary Land, and to the Birkelund Fjeld, Splitbæk, and Kuglelejet formations of Kronprins Christian Land (Kilen). The Berriasian to Hauterivian Rurikfjellet Formation (Svalbard) correlates with the Dromledome and Lichen Ryg formations from Kilen and the middle part of the Ladegårdsåen Formation from East Peary Land. The Galadriel Fjeld Formation from Kilen and the upper part of the Ladegårdsåen Formation (East Peary Land) are comparable to the Helvetiafjellet and Carolinefjellet formations of Svalbard. These comparisons between Svalbard and North Greenland are combined with stratigraphical information from neighbouring regions in palaeogeographical reconstructions. Five selected time slices are presented within a setting of the most recent plate tectonic reconstructions for the area.

Sev eral sec tions re cord the re la tion be tween the "black flysch" and Up per Cre ta ceous red shales in the Grajcarek thrust-sheets. In all the sec tions stud ied the "black flysch" ap pears in the core of imbricated folds or thrust-sheets, whereas the limbs are com posed of Up per Creta ceous de pos its. The tran si tional beds be tween the " black flysch" and the Up per Cre ta ceous red shales are com posed of green and black bi tu mi nous shales, green and red radiolarites and cherty lime stones. Biostratigraphical in ves ti ga tions have re vealed a sim i lar type and sequence of micro fauna as sem blages in all the sec tions stud ied and sig nif i cant redeposition of Ju ras sic cal car e ous ben thic foraminifera, cal car e ous nannoplankton, molluscs, sponge spicules and cri noid el e ments. The Cre ta ceous age (Aptian/Alb ian-?Cenomanian) of the "black flysch" is shown by the pres ence of ag glu ti nated foraminifera and microfacies data. These de pos its are un der lain by a Kimmeridgian-Aptian radiolarite/lime stone con densed suc ces sion and over lain by Turonian-Campanian hemipelagic red shales and Maastrichtian/Lower Paleocene con glom er ates and thick-bed ded silicilastic turbidites of the Jarmuta For ma tion.
