“…The two samples from the lower series, 63016 and 63023, correspond well with the average of the lower series (Rasmussen & Noe-Nygaard 1969, Bollingberg, Brooks & Noe-Nygaard 1975 and could be classified as FETI-basalts characteristic of plume activity.…”

08 The pyroxenes from one flow from the lower lava series, one from the middle, and one from the upper lava series of the Faeroe Islands have been investigated by microprobe. The flow from the lower series has augite as the only pyroxene, the flow from the middle series has bronzite as phenocrysts and augite and pigeonite, and the flow from the upper series has augite and pigeonite. 30 analyses of these pyroxenes are presented, comprising eight elements: Si, Ti, Al, Fe, Mn, Mg, Ca and Na, and the formulae based on four cations are calculated. Variations in major elements are shown in figs. 2-8; in these diagrams are also used the results of 116 partial analyses, comprising only Mg, Fe and Ca. The variations in minor elements and their distribution between augites and Ca-poor pyroxenes are discussed. In a MnO-TiO,-Na,-O diagram (Nisbet & Pearce 1977), the augites plot mainly in the ocean-floor basalt field, but a number of analyses fall in the field common to all the basalt types. F,-F, values (Nisbet & Pearce 1977) correspond partly to the field where ocean-floor basalts and within-plate tholeiites overlap, and partly to the field where ocean-floor and volcanic arc basalts overlap.

“…The Faeroe Islands consist exclusively of floodbasalt lavas poured out subaerally in the earliest Tertiary and forming a pile 3000 m thick (Noe-Nygaard & Rasmussen 1968, Rasmussen & Noe-Nygaard 1969. This pile is divided into three series: the lower series, the middle series and the upper series (Noe-Nygaard 1962).…”

Landslides and related phenomena on Suduroy, the Faeroe Islands

The formation of landslides on Suduroy, the Faeroe Islands, is greatly favoured by the geological setting and the tectonic pattern of the island. Some landslides involve lavas, the coal-bearing sequence and the luff-agglomerate zone, which served as lubricating agents for the slipped masses. The biggest landslides occur along scarps with the direction NW-SE and are believed to have a relation to the lamellar zones which are characterized by closely spaced fissures. The NW-SE trend is the main tectonic direction on Suduroy.

“…2 shows the situation of the profiles to be observed . Profile 1 was placed in the d ireotion of the rid ge and was extended over Strømø by four land stations (1)(2)(3)(4). The aim of this profile is the observation of d iscontmuities of the rid ge and island s. Thereby reversed profiling can give real velocities.…”

Skjálvtafrøðiligar dýpdarkanningar vóru gjørdar í samvinnu við laarda háskúlan í Hambung (Institut fiir die Physik des Erdkórpers) á rygginum millum Føroya og íslands í døgunum 9. til 14. juli 1970. Við tveggja-skipaháttinum vóru skjálvtafrøðiligar afturvarp- og brotmátingar gjørdar á sjónum. 1 Streymoy fylgdu 4 landstøðir við spreingingunum á sjónum. Uppsetingar av skjálvtaritunum frá landstøð nr. 2 eru sýndar. Einans ein Lind kundi verða rannsakað við at bera saman skjálvtafrøðiligu viðburðirnar. Snarleikin 6,1 (5,6 • 5,7) km/s er ein P^bylgjiu-snarleiiki og 3,4 km/s ein S-bylgju-snarleiki. Teir eru at vísa seg snarleikar hjá undirstøðinum undir basaltgrýti Føroya.
