Sar-e-Sang River, Sar-e Sang (Sar Sang; Sary Sang), Koksha Valley (Kokscha Valley; Kokcha Valley), Khash & Kuran Wa Munjan Districts, Badakhshan, Afghanistan
|Comments:||The blue Haüyne has a cell edge of 9.08 A (Fernando Camera (2013))and the green 9.05 A.(Fernando Camera (2010) Both have similar modulated structures. |
A few dozen specimens of green Haüyne were recovered. Dudley Blauwet (2008) has photos of the material in situ. Fewer darker green Haüynes later emerged.
PXRD at the Royal Ontario museum gave Lazurite C with gypsum for the early green material (Malcolm Back (2009)). Fernando Camara (2010) found it has a cell edge of 9.05 A and a 45 A modulated structure.
A Raman analysis at the University of Arizona gave both Haüyne and Lazurite for the blue Hauyne.
The problem is that no natural sulfide dominant Lazurite has ever been observed. They can be synthesized but are unstable. All 'Lazurite' specimens are actually sulfate dominant Haüyne. The specious argument to call some powder patterns Lazurite stems from the observation that sulfide is smaller than sulfate and so Haüynes with small unit cells should have more sulfide, but there is never enough to be sulfide dominant.
