Interpretation of two gravity profiles across the Engebøfjellet rutile-bearing eclogite deposit

Abstract

Confidential to 31.12 2002. Gravity measurements have been carried out along two profiles across the Engebøfjellet rutile-bearing eclogite deposit. The main objective of the investigations was to delineate the morphology and subsurface extension of the eclogite body, given results and constraints from surface mapping and drillholes. Two alternative models are proposed for both profiles. The volume and mass estimates for the models given must be mistaken for the total volume and mass of the whole eclogite deposit, which is larger. This is because the eclogite deposit extends to the east at a longer distance thean would affect the calculated reponse.
