SUMMARY
The present paper deals with intrusive rocks (Basalts) of the Faroe
Islands. The Plateau*Basalt sequence is briefly mentioned: 1. Lower
Basalt Sequence, 2. Coabbearing Sequence, 3. Tuff=AggIomerate Se«
quence, 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 diffe*
rent 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
PlateausBasalt sequence.
