Abstract

The paper presents the method and results of measurements carried out at four secular points: P, — Wilczekodden, P2 — Hyttevika, P3 — Gashamna and P4 — Treskelodden. No essential changes were found in the distribution of the anomalous field ΔT with respect to the results of observations made in 1979.

Abstract

This paper presents the results of magnetic mapping carried out in the area of the metamorphic series of Ariekammen and Skoddefjellet. On the basis of qualitative interpretation of measurements a number of anomalous zones were distinguished, whose position can be correlated with local changes in mineralitation and polymetallic ore content in the Fuglebergsletta area. The SE-NW orientation, skew to the almost meridional run of the layers of slates and marbles making up the metamorphic complex, dominates in the course of the anomalous zones.

Abstract

The results and method of measurements of D, H and T carried out at Hornsund in the summer of 1979 are presented. The relative and absolute values of these elements are given in reduction to the Polish magnetic station at Hornsund. An initial evaluation of changes in the magnetic field from 1957 to 1979 is carried out.

Abstract

This paper describes the method of prospective magnetic research under natural conditions of strong interference by the external variable magnetic field. This method of synchronized measurements, when some given assumptions are satisfied, permits magnetic survey of the accuracy 1-2 nT to be carried out. It was used in detailed investigations of weak anomalous fields.

Abstract

This paper discussed the results of pilot magnetic investigations carried out at the foot of the Fugleberget mountain and in the Skå valley in the area of the morthwestern shores of the Hornsund Fiord. The investigations showed the large usefulness of the magnetic method in stratification of different rock types which occur within the metamorphic complex, and, in the case of magma intrusions, they found that dolerity dykes are characterized by high, uniform magnetization and very simple geometrical form.

Abstract

This paper discusses the results of gravimetric and magnetic investigations carried out on the Hans Glacier (Hansbreen) in the area of the Hornsund Fiord in Spitsbergen. These pilot investigations were performed in profiles running across to the extension of the glacier. Analysis of the magnetic measurements permits the supposition that in the base of the glacier there are amphibolites assigned to the Skålfjellet series, one of the oldest links of the metamorphic complex in Spitsbergen. Fig. 3 shows the behaviour of the amphibolites determined from the qualitative and quantitative properties of the anomalies ΔT. This paper also determined the thickness of the glacier in a cross-section 1.5 km distant from its front. From interpretation of the gravity anomaly, thickness varies between several and more than 100 m, taking the highest values in the central part of the glacier.
