A Note on some Geo-Electrical Measurements
at Tjørnuvík, Streymoy
By H. Lykke Andersen1)
Abstract
In July 1967 nine electrical soundings were measured at
Tjørnuvík, Streymoy, the Faroe Islands. The main purpose
was to determine the thickness of the sedimentary layers, which
overlay the basalt. The measurements show that the sediment
cover mainly consists of three layers (Fig. 5). The average
thickness of the sedimemt cover is found to be about 4 m, the
maximum thickness being about 7 m. The thiokness of the
layers decrease generally towards the east. Presumably, the
surface of the basalt has a moderate relief and everywhere
the surface seems to be above present sea-level. (Fig. 6).
Introduction
In July 1967 a series of electrical resistivity measurements
was carried out in the Faroe Islands by means of a highly
sensitive measuring apparatus, as described in Bentz (1961).
This article deals with measurements made at Tjømuvík,
Streymoy.
Tjørnuvík is situated at the southern end of a small fjord,
which cuts into the northcoast of Streymoy. The form of the
