| Det er påvist Fe-Ti-mineraliseringer på flere steder, de fleste stratigrafisk høyere oppe enn sulfidmineraliseringene Skogneset, Nonsdagsdalen og Nonsdagstind. De opptrer som lag eller linser med mektighet 0.1-0.5m konkordant med sidesteinen, og består av finkornet massiv magnetitt og ilmenitt med noe amfibol, eller som disseminasjon i amfibolitt. Magnetitt og ilmenitt opptrer som egne korn eller som ilmeno-magnetitt. Kobberkis, svovelkis og magnetkis opptrer aksessorisk. Hovedskjerpet: Det ble funnet bare ett skjerp i Fe-Ti-mineraliseringene, et 1m3 skjerp ved UTM 427680 7761540 i et 30cm mektig finkornet, massivt magnetitt-ilmenitt-lag (prøve 03). Massiv gabbro i ligg, foliert amfibolitt i heng. Foliasjon: 295/50. Ved UTM 427650 7761510 opptrer et 30cm mektig lag av semimassiv Fe-Ti-oksyd i finkornet amfibolitt (02). Skjerp 1: Ved UTM 426750 7761600 opptrer nok et 30cm mektig lag av finkornet massiv magnetitt-ilmenitt (01) i finkornet amfibolitt i gabbro. Samme finnes også ved UTM 427350 7761700. |
