Vest for Herjangen tettsted ca. 75 m.o.h. er det i kalkkontakten 1m granatfels med litt MnO-belegg. En analyse av felsen gjort ved Norsk Jernverk A/S, viser Fe tot. 19.2%, Fe magn. 15.4%, P 0.21% og MnO 11.5% |

Flood, Boye , 1961 |
Befaring av Herjangen jernmalmfelt, Ankenes. |
;Norges geologiske undersøkelse;FAGRAPPORT;Bergarkivet; No.BA 3477;2 pages |
Abstract: | |
Rapporten omhandler en malmgeologisk beskrivelse og vurdering av Herjangens jernmalmfelt, beliggende på NV-siden av Herjangsfjorden (sannsynligvis samme som forekomst IV 183 "Bakkejord" eller IV 184 "Tollviken" i A.O. Poulsens oversikt (NGU 204, side 79, m.m.)) Flood anser jernmalmfeltet for å være uten praktisk betydning. |

Rapport over Torteneset jern-manganmalmfelt i Herjangen, Ankenes herred. |
;Norges geologiske undersøkelse;FAGRAPPORT;Bergarkivet; No.BA 1995;2 pages |
Abstract: | |
Rapporten er en malmgeologisk beskrivelse og vurdering av Tortenås på nordsiden av Ofotfjorden. Rapporten har opplysninger om feltets beliggenhet og utstrekning, malmens mektighet og kvalitet (herunder noen kjemiske analyser). Rapporten konkluderer med at malmen er fattig, og oppdragsgiver anbefaler derfor ikke å investere i videre undersøkelser i feltet. |
