Formula:

Ca(Fe²⁺,Mg)₆(PO₄)₂(SiO₄)₂

Colour:

Yellow-brown to orange-brown

Lustre:

Vitreous

Hardness:

4 - 5

Specific Gravity:

4.02

Crystal System:

Trigonal

Name:

Named by A.C. Roberts, J.A.R. Stirling, J.D. Grice, T. Frisch, R.K. Herd, and J.L. Jambor in 1993 in honor of James Merritt Harrison (20 September 1915, Regina, Saskatchewan, Canada – 6 July 1990, Canada), geoscientist and former Director of the Geological Survey of Canada (1956-1964). He was awarded the Logan Medal from the Geological Association of Canada in 1969.

Type Locality:

ⓘ Arcedeckne Island, Kitikmeot Region, Nunavut, Canada

The material from Czech pegmatites is manganese- and phosphorus-bearing. The latter substitution is related to Si deficiency.

The pegmatitic occurrence suggests the mineral to be stable lower P–T conditions than these reported for the holotype (Vácha & Škoda 2022).
