GEOLOGY OF GREENLAND SURVEY BULLETIN
VOLUME 175

Exposure of the Neill Klinter Group in the type area along Hurry Inlet in the south-eastern part of Jameson Land. Sandstones and mudstones of the Neill Klinter Group overlie the scree-covered Kap Stewart Group. Fine-grained units in the Neill Klinter Group are intruded by Tertiary sills. The view is from Astartekløft towards the north. The airport at Constable Pynt is seen on the second delta. Exposed section c. 200 m thick.

Abstract
Dam, G. & Surlyk, F. 1997: Stratigraphy of the Neill Klinter Group; a Lower - lower Middle Jurassic tidal embayment succession, Jameson Land, East Greenland. Geology of Greenland Survey Bulletin 175, 80 pp.
The sediments of the Neill Klinter Group of Jameson Land, East Greenland were deposited in a wide, shallow, wave, storm and tidally-influenced marine embayment situated at the western margin of the Jurassic seaway between Greenland and Norway. The group is formally defined and a new lithostratigraphic scheme is erected on the basis of recent sedimentological, biostratigraphic and sequence stratigraphic studies. The Neill Klinter Formation is changed to group rank; the Rævekløft, Gule Horn and Ostreaelv Members are revised and raised in status to formations, and the Sortehat Formation is redefined and included in the group. The Gule Horn Formation is divided into two new members and the Ostreaelv Formation into seven new members. The Neill Klinter Group is up to 450 m thick.
Sandy and muddy material was transported into the embayment from source areas to the east, west and north. A number of sub-environments are represented in the succession, including: restricted and bioturbated offshore, storm-dominated offshore transition zone, wave and storm-dominated shoreface, storm-dominated sandy shoal, subtidal sand sheet, ebb-tidal delta, tidal channel, wave and storm-dominated lagoon, and ephemeral stream delta.
The Neill Klinter Group consists of seven sequences and is characterised by a near absence of parasequences, interpreted as reflecting high influx rates of sand into the land-locked embayment. Continuous filling of accommodation space and erosion resulted in amalgamation of sedimentary packages, and poor development of facies cyclicity.
