The Heindalen Fe-Ti-V deposit is located 9 km SW from the major Rødsand deposit, and is found in the same geological setting. It is associated with Fe-Ti oxide-rich amphibolites surrounded by Palaeoproterozoic orthogneisses. The deposit is found on both sides of the Heindalen river, of which the eastern part comprises a possible resource of 4.8 mill.t. and the western part 0.9 mill.t. The ore comprises disseminated to semi-massive Fe-Ti oxides.

Abstract:

Oppramsing av hele landets jern-titanforekomster, hvorav 15 trekkes fram som de største. Hver forekomst beskrives ut fra befaring med geologiske og dels kjemiske data. Oppredningsresultater presenteres også. Oppramsing- en går fra Hedmark til Finnmark i nord.

The Rødsand Fe-Ti-V deposits, Møre, Western Norway

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.402;39-49 pages

Abstract:

Rødsand Gruber, situated west of Sunndalsfjord, West Norway, has been an important supplier of Fe-Ti-V ore for more than 80 years. Eight major orebodies, intimately associated with strongly folded amphibolites, produced some 15 Mt of crude ore yielding 25-30% magnetite, 3.5-4% ilmenite and 0.15-0.20% V. The amphibolites and their host rocks belong to the Raudsand group, mainly comprising quartz dioritic, grandioritic and granitic gneisses. Rh/Sr isochrons indicate an age of about 1700 Ma for the gneisses. The Rødsand deposits in its present form developed during deformation and metamorphism. High An-contents of plagioclases, the existence of relict pyroxenes and the sulphide paragenesis indicate that the deposit is a product of the fractional crystallization of a basic magma.
