| Abstract | INTRODUCTION The products of the abandoned Snæfellsnes rift system active in Iceland from 15–7 Ma consist mainly of flat-lying tholeiitic basalts, with restricted areas of silicic volcanics. A diversity of rock types results from the interfingering products of shield volcanoes and eruptive fissures, similar to Iceland’s current volcanic activity. The paleorift axis is estimated to pass through Vididalsfjall, a mountainous NNW-trending ridge at the base of the Skagi Peninsula. The northern peaks of Vididalsfjall are marked by mafic and slicic intrusives. At this location and in the adjacent mountain range Vatnsdalsfjall, which has a parallel trend and lies 10 km east of the rift axis, several unusual structural and petrologic features have been observed (Annells, 1968). |
