Rutile-bearing eclogites in the Sunnfjord region of Western Norway. |
;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.402;65-71 pages |
Abstract: | |
Rutile-bearing eclogites from the basal gneiss-complex of the Sunnfjord region in Sogn og Fjordane Fylke are potential titanium reserves, and have been the subject of prospecting activities during the last decade. The eclogites occure as lenses and pods in Precambrian gneisses and are believed to have been formed by the recrysrallization of basic igneous rocks during high-pressure Caledonian metamorphism. They are composed principally of garnet, omphacitic clinopyroxene and barroisitic amphibole. Rutile con- centrations are generally in the range 1 to 4 wt.%, although higher concen- trations occur locally. About 90% of the titanium in the eclogites is contained in rutile. Some large eclogite bodies are each estimated to contain at least 100 Mt. containing approximately 3% rutile, which is presently uneconomic. |

Fureviknipa og Engebøfjellet rutilforekomster ved Førdefjorden, Sogn og Fjordane. |

Abstract: | |
I Førdefjordområdet opptrer en rekke forekomster av relativt rutilrike eklogittbergarter. I 1990 ble det utført ny prøvetaking av to av disse forekomstenee, Furuviknipa i Førde kommune og Engebøfjellet i Naustdal kommune. Begge forekomstene inneholder relativt store partier med i størrelsesorden 3 % rutil. Med utgangspunkt i at det kreves en rutilgehalt på omtrent 5 % over en forekomststørrelse på 10-15 mill. tonn for å kunne gi grunnlag for økonomisk utnyttelse, vurderes disse forekomster å ikke være drivbare på rutil. |
