Originally assumed to be PbHgAs2S6.

Colour:

Bright orange, red

Specific Gravity:

5.93 (Calculated)

Crystal System:

Monoclinic

Name:

Named in honor of Dr Farahnaz Daliran (b. 1953), research associate at the Karlsruhe Institute of Technology, Germany for her contributions to research on ore deposits, especially Au, Zn and Fe, in Iran.

Originally, and erroneously, reported as ludlockite from Zarehehuran, Takap, Takht-e-Suleiman massif, Azerbaijan.

Daliranite has an incommensurately modulated structure (Lanza et al., 2019).

Crystal System:

Monoclinic

Cell Parameters:

a = 19.113 Å, b = 4.233 Å, c = 22.958 Å
β = 114.78°

Ratio:

a:b:c = 4.515 : 1 : 5.424

Comment:

Reinvestigation by Lanza et al. (2019) demonstrates the mineral is orthorhombic (space group Pnma for average structure) with a = 21, b = 4.3, c = 9.5 Å, and incommensurately modulated.
