Type Occurrence of Graftonite

Type Locality:Melvin Mountain, Grafton, Grafton Co., New Hampshire, USA
Year of Discovery:1900
Geological Setting of type material:Complex granite pegmatite.

Occurrences of Graftonite

Geological Setting:Complex granitic pegmatites.

Physical Properties of Graftonite

Lustre:Sub-Vitreous, Resinous, Greasy
Diaphaneity (Transparency):Translucent
Colour:Usually reddish brown, occasionally light brown, rarely salmon-pink; nearly colorless in transmitted light.
Comment:May be dark brown due to alteration.
Streak:White to faintly pink, when unaltered.
Hardness (Mohs):5
Tenacity:Brittle
Cleavage:Distinct/Good
On {010}, good; on {100}, poor, but not eaily observed.
Fracture:Irregular/Uneven, Sub-Conchoidal
Density (measured):3.67 - 3.79 g/cm3
Density (calculated):3.95 g/cm3
Comment:Measured values vary with the ratio of Fe:Mn:Ca. 3.775 = measured (from Nickel Plate Mine, SD, USA).

Crystallography of Graftonite

Crystal System:Monoclinic
Class (H-M):2/m - Prismatic
Space Group:P21/b {P1 1 21/b} {P21/c} {P1 21/c 1} {P21/a}
Cell Parameters:a = 8.87Å, b = 11.57Å, c = 6.17Å
β = 99.2°
Ratio:a:b:c = 0.767 : 1 : 0.533
Unit Cell Volume:V 625.06 ų (Calculated from Unit Cell)
Z:4
Morphology:Generally found as parallel lamellae in triphylite or occasionally with other primary phosphates in granite pegmatite. Morphological "crystals" are essentially unknown. Pseudomorphs of heterosite after graftonite "crystals" are stout prismatic; also occurs as rough composite crystals of graftonite in triphylite.
Comment:American Mineralogist 67:826 (1982) structure; Neutron diffraction indicates three distinct cation sites
