| Mineraliseringen er særlig apatitt-cummingtonitrik og består av følgende 3 laglinser langs en 5 km lang strøklengde: Lengde Tykkelse ----------------------------------------------------------------------- Haralibekken 1000 m 3 lag 0,5-2m tykke +Lomtjønnmyrbekken innenfor 30m bredde Rasthaugen 500m Et lag ca. 2m V f. Oppdalsli 300m 5-10m Haralibekkdraget er den rikeste mineraliseringen med middelskornet magnetitt. Det er ikke sammenheng mellom de tre ovennevnte malmer. |
