About AbelsoniteHide

00068130014946287312681.jpg
Philip Hauge Abelson
Formula:
Ni(C31H32N4)
Colour:
Pink-purple, dark greyish purple, pale purplish red, reddish brown
Lustre:
Adamantine, Sub-Metallic
Hardness:
2 - 3
Specific Gravity:
1.33 - 1.48
Crystal System:
Triclinic
Name:
For American physicist Philip Hauge Abelson (27 April 1913, Tacoma, Washington, USA - 1 August 2004, Bethesda, Maryland, USA). He was co-discoverer of element 93 (neptunium), editor of the periodical Science (1962-1984), and director of the Carnegie Institution of Washington's Geophysical Laboratory (1953-1971).
Chemically a nickel porphyrine derivative, classified as deoxophylloerythroetioporphyrin. Unique combination of elements; the only organonickel mineral known. Formed at depth (Milton et al., 1978), likely from a chlorophyll (but likely not the chlorophyll-d) (Storm et al., 1984).

Abelsonite is accompanied by its structural norisomer; the surrounding shale contains other Ni porphyrins, which represent a series of more extended homologues.

Structure details (Storm et al., 1984): (1) methyl groups in the 2, 3, 7, 12, and 18 positions, (2) ethyl group in the 8 and 17 positions. According to Milton et al.(1978) the molecules in abelsonite are not planar. The substitution pattern in the mineral is genetically related to a typical chlorophyll. The potential precursor to abelsonite is 17-desethyl, 17-propionic acid.

Worth of notice is an unnamed mineral coded as 'UM1984-14-CH:ClNOV', which is a natural vanadyl deoxophylloerythroetioporphyrin, the second known metalloporphyrin mineral, although not isostructural with abelsonite.

Geological Setting:
Small aggregates, to 1 cm, of thin laths or

Type Occurrence of AbelsoniteHide

General Appearance of Type Material:
Aggregates of platy crystals; as patches, sometimes over 2 mm in diameter.
Place of Conservation of Type Material:
The Natural History Museum, London, England, number 1979,135.
National Museum of Natural History, Washington, D.C., USA, numbers 143566, 145712.
Geological Setting of Type Material:
Mahogany Zone oil shale; found in six stratigraphical zones ( M9, M7, M2, L6, L0, and K1); its genesis is connected with unique geochemical conditions of Lake Uinta; likely formed due to chlorophyll diagenesis; abelsonite's relatively insoluble precursor was likely transported by an aqueous solution towards sediments of favorable lithology.
