| Fjellområdet mellom Engebø-Redalsgrend og Naustdal, en strekning på 12 km, inneholder en rekke store og små lokaliteter av eklogitt. Rekognoserende prøvetaking av NGU i 1978 (Korneliussen 1978) påviste forekomster med lokalt høyt titaninnhold uten at dette ble fulgt opp med mer detaljerte undersøkelser. Noe videre rekognosering i forbindelse med NGUs samarbeidsprosjekt med DuPont/Conoco i 1992-97 gav heller ikke positive resultater. Området ble imidlertid ansett å være av stor interesse for framtidige ressurser av rutilførende eklogitt, og NGU gjennomførte derfor i 1998 tyngdemålinger (Elvebakk m.fl. 1999) som ble videreført med nye målinger i 1999 (Dalsegg m.fl. 1999). Dette resulterte i påvisning av en rekke tyngdeanomalier som anses å skyldes eklogittbergarter på dypet. Noen av disse anomaliene er klart relatert til utgående forekomster av rutilførende eklogitt, mens andre ikke kan relateres til kjente eklogittforekomster. Den mest interessante av disse anomalier ligger i området Steinkrossen-Vindkjegla 700 m.o.h. 3-4 km vest for Naustdal sentrum og 3 km nord for Holmeset ved Førdefjorden. Den gravimetriske tolkningen viser at anomalien representerer et tungt bergartslegeme av betydelig størrelse og som sannsynligvis strekker seg helt ned til havnivå. Anomalikilden stikker opp i overflaten i form av eklogitt med varierende rutilinnhold fra 1-2 % til 5 %. Denne forekomsten er potensielt betydelig. Eventuelle videre undersøkelser vil kreve kjerneboring. |

| 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. |

| Abstract: | |
| Gravity measurements have been carried out along 10 profiles in the region in between Naustdal and Engebø. The objective of the measurements was to detect new heavy bodies of eclogite and to map the extension to the depth of the known eclogite at Bygdahaugen. To confirm the ability of the gravity method, two profiles were measured across the known eclogite deposit in Naustdal. The size (depth) of this deposit should be estimated. The results show that the gravity method is well suited for such investigations and the Naustdal deposit was clearly indicated bye a strong anomaly. To the east of Bygdahaugen a new body with a possible density of around 3400 kg/m3 (eclogite) was indicated body. The depth extent is estimated to 600 m in the model. The size of the body is probably in the same range as the Engbø deposit, approximately 400 mill. tons. More detailed investigations, both geophysical and geological, have to be carried out before drilling can start. At least four gravity profiles should be measured which will confirm the anomalies and lead to an improved estimate of the size of the indicated deposits. |

| Abstract: | |
| (Forkortet) Important rutile deposits in Norway are two of main types: eclogite rutile deposits in Western Norway and metasomatic rutile deposits in the Bamble province of southernmost Norway. Eclogite deposits formed by the metamorphic tranformation of Proterozoic mafic rocks during Caledonian high-pressure metamorphism at 400 Ma. Rutile-bearing eclogites are found in various geologicl sub-provinces from the Bergen region in the south to the Kristiansund region in the north. The metasomatic rutile deposits, such as various rutile-bearing amphibolites and albitites in the Bamble geological province in the southernmost Norway, formed by the metasomatic tranformation of ilmenite-bearing gabbroic and amphibolitic rocks at approx. 1150 Ma. |
