Sammendrag
A rock-type identified as kentallenite is reported from the southwestern partof the Helgeland Nappe Complex, Central Norway. The kentallenite is ahypabyssal rock and belongs to a suite of appinitic mafic dykes and smallstocks which are spatially and temporally associated with phenocrysts ofolivine and zoned clinopyroxene in a groundmass which usually consists ofplagioclase, biotite, K-feldspar, clinopyroxene, orthopyroxene, ilmenite andapatite. A K-Ar whole-rock date of 399 \u00B1 10 Ma can be interpreted either as acooling age related to the emplacement of the rock, or it can be related to theemplacement of the rock, or it can be related to an Early Devonian thermalevent.
