Yvirlit yvir innskotin grótsløg í Føroyum: General View of Intrusive Rocks [Basalts] of the Faroe Islands

Abstract

The present paper deals with intrusive rocks (Basalts) of the Faroe Islands. The Plateau«Basalt sequence is briefly mentioned: 1. Lower Basalt Sequence, 2. Coahbearing Sequence, 3. TuffsAgglomerate Sequence, 4. Upper Basalt Sequence, 5. Intrusive Rocks. Next the different types of intrusives are treated: 1. Irregular intrusive Basalts, 2. Sills (transgressive), and 3. Dikes. Irregular intrusive Basalts from Suðuroy, Tindhólmur and Vágar are described. The following sills are dealt with: 1 from Fugloy, 1 from Svínoy, 3 from Streymoy and 2 from Eysturoy. Dikes are only briefly mentioned. Finally the different intrusive types are placed in the stratigraphic sequence, and it is concluded that all three types of intrusives are most likely related — belong to the same intrusive phase — and are younger than the whole Plateaus Basalt sequence.
