Gravity measurements in eclogite mapping, Naustdal, Sogn og Fjordane, 1999.

Abstract

The gravity measurements in the region between Naustdal and Engebø have been supplemented with 6 profiles. The objective of the measurements was to confirm the anomalies and the size of the indicated bodies from the 1998 investigations. Two profiles east of Naustdal eclogite deposit have shown that the deposit have a limited extension to the east. In the area east of Bygdahaugen, four profiles have confirmed the anomalies from 1998, and have better mapped the extension of the eclogites bodies. All profiles in this area indicates eclogite bodies, and the result from the modelling support the conclusions from 1998. The size of the possible eclogite body seems to be in order of 400 mill. tons.
