Iflg. Stolz (1908) kan denne midtre malmsone følges fra Øvrefors sørover til Brandkløvåsen, en strekning på vel 6km. Malmsonen ligger i dalbunnen og er for det meste overdekket. Ett skjerp ble funnet sør for Stormyra, UTM 415370 7276240. Det er et 6x4m og 2m dypt skjerp innsprengt i kollens øst- helling (35m3 tipp). Her står båndet, relativt fattig jernmalm i hele skjerpet (prøve 02) - mektigheten er minst 5m. 01 er gjennomsnittsprøve over disse 5m. I ligg: porfyrisk dioritt med granittpegmatittbånd. Ved UTM 415250 7276050 er blottet en vestligere horisont som er svakere mineralisert. Den fortsetter sørover til Holmsætra.

Abstract:

Rapporten beskrivver en 8 dagers undersøkelse av Eiterådalens jernfelt og gir innledningsvis en almindelig oversikt over beliggenhet og topografi. Malmsonene ligger i pressede gneisbergarter og er lite avdekket. Malmmineraliseringen er magnetitt og beskrives som oppredningsmalm. Malmsonene er fulgt opp med magnetometer og det er gitt en detaljert beskrivelse av de enkelte malmsoner. På grunnlag av de utførte undersøkelsene er det foretatt malmberegninger som konkluderer med videre undersøkelser.

Abstract:

Cambro-Silurian rocks with large intrusive masses cover most of the area. In the south-westernmost part there are also deeper lying rocks. This part is referred to as the basal gneiss region, while the rest of the area is called the Nordland syncline. In the basal gneiss region there are 3 distinct stratigraphic units: 1. Basal gneisses of supposed Pre-cambrian age. 2. Lower Cambro-Silurian division: micaceous gneisses. 3. Upper Cambro-Silurian division: lime-silicate gneisses with amphibolites and micaceous gneisses, the greater part of which is dark, rather basic and transitional to hornblende-bearing gneiss. Locally also crystalline lilmestone. The three rock units in the basal gneiss region are intensly folded together, and the boundaires between them are concordant. It is thus clear that the basal gneiss has been strongly influenced by the Caledonien orogeny. Steeplimbed, isoclinal folds are most common, but some well-developed synclines and anticlines are present. The greater part of the region has a strike direction ENE to NE. In the northernmost part the fold axes have a northerly plunge. At Tenfjord lime-slicate gneisses are thrust towards the basal gneiss.The northern and greater part of the Nordland has an approximate synform.
