Forekomsten finnes på nordsiden av nedre Skaddjacåkkajavrit (414 moh.) og like øst for utløpsoset. Mineraliseringen opptrer i dolomitt 10-15 m vest for kontakten mot mylonittisk grønnstein. Kontakten representerer en skyvesone som faller 30° mot vest. Dolomitten, som når mektigheter på 20-30 m, utgjør en del av en fyllittsekvens som ligger under overskjøvne grønnsteiner og granittiske bånd- og åre-gneiser av tidlig proterozoisk alder (Roberts ). Mineraliseringen er knyttet til en 5-10 m bred stratabundet sone i de massive til skifrige dolomittene, og omfatter tensjonssprekker fylt med grovkornet hematitt, kvarts og kloritt. Hematitten i de 2-3 cm brede årene er stedvis deformert med dannelse av buete og krenulerte hematitt-aggregater. Massive dolomitt-lag og -bånd fører ofte årenett og disseminerte aggregater av grovkornet hematitt, samt finkornet, rødlig disseminasjon langs silifiserte soner (Jaspis?) som kan følges 2-3 m langs strøket. Det stratabundete årenettet gjennomsettes lokalt av kvartsganger med mindre grovkornet hematitt. Mineraliseringens alder er usikker, men den synes knyttet til den kaledonske dekketektonikk.
