Crystallography
- Twinning
Twins (only visible in X-ray photographs): mirror on (100) and 60° rotation around [013] for the tetragonal component.
- Type-locality form
occurs in veinlets <1 mm wide of lamellae (maximum length 300 μm) in flow texture
- Comment
Misfit-layer compound of the cylindrite type, with a structure that results from the combination of two heavily modulated triclinic Q and H subcells with a common q wave vector and only one shared reciprocal axis (stacking direction). The Q layer, ~(Pb0.7Sb0.3S), is derived from the NaCl archetype: a = 5.8218(6), b = 5.8645(5), c = 12.1443(13) Å, α = 92.327(7), β = 78.533(9), γ = 90.019(8)°; the H layer, ~(Sn0.85Cu0.3S2), is derived from the CdI2 archetype: a = 3.6661(3), b = 6.3138(5), c = 11.9028(10) Å, α = 92.490(7), β = 90.590(8), γ = 89.986(8) Å.
