| For beskrivelse av Store Fiskevatnhorisonten, se FI0331 Store Fiskevatn Vest. Malmen har forbindelse til malmen ved Reitanvatn og Store Fiskevatn Vest. Geologien er komplisert, med få blotninger, så malmens stratigrafiske plassering er usikker. Malmen består av en rekke linser av variabel kvalitet (10 - 30 % Fe magn.), den har trolig sammenheng under overdekket. Det finnes noen blotninger av hornblendegneis i og ved malmen, men vulkanittsekvensen med malm er her tynn. Malmareal: 8000 m2. |
