Abelsonite, synonym nickel porphyrin, is a mineral of nickel, carbon, hydrogen, and nitrogen with formula: NiC31H32N4. It forms purple to reddish brown triclinic crystals. The crystals are soft, with a Mohs scale rating is 2 to 3. It has a low specific gravity of 1.45.
It was first described in 1975 for specimens in oil shale from the Green River Formation, eastern Uintah County, Utah. It is named after Philip Hauge Abelson, an American physicist.
