K/Ar age determinations on dolerites from southern Peary Land

N. Henriksen, H.F. Jepsen

    Research output: Chapter in Book/Report/Conference proceedingChapter in report


    Whole rock K/Ar age determinations have been undertaken on two Precambrian discordant sills and one post Lower Cambrian dyke from the Jørgen Brønlund Fjord - Midsommersø area. The rocks, which were collected by H. F. Jepsen, were chosen for age determination to obtain a minimum age of the pre-tillitic sandstones in southern Peary Land and from this to get an indication ofthe age of the youngest sedimentation in the Carolinidian geosyncline (Haller, 1961).
