Discovery of Disulfane (H<sub>2</sub>S<sub>2</sub>) in Fluid Inclusions in Rubies from Yuanjiang, China, and Its Implications
Raman spectra of fluid inclusions in gem rubies from Yuanjiang deposit (China) within the Ailao Shan-Red River (ASRR) metamorphic belt showed the presence of compounds such as CO<sub>2</sub>, COS, CH<sub>4</sub>, H<sub>2</sub>S, and elemental sulfur (S<sub>8...

| description | Raman spectra of fluid inclusions in gem rubies from Yuanjiang deposit (China) within the Ailao Shan-Red River (ASRR) metamorphic belt showed the presence of compounds such as CO<sub>2</sub>, COS, CH<sub>4</sub>, H<sub>2</sub>S, and elemental sulfur (S<sub>8</sub>), accompanied by two bands at approximately 2499 and 2570 cm<sup>−1</sup>. These two frequencies could be assigned to the vibrations of disulfane (H<sub>2</sub>S<sub>2</sub>). This is the second case of the sulfane-bearing fluid inclusions in geological samples reported, followed by the first in quartzite from Bastar Craton of India. The H<sub>2</sub>S<sub>2</sub> was likely in situ enclosed by the host rubies rather than a reaction product that formed during the cooling of H<sub>2</sub>S and S<sub>8</sub>, suggesting sulfanes are stable at elevated temperatures (e.g., >600 °C). By comparing the lithologies and metamorphic conditions of these two sulfane-bearing cases (Bastar and Yuanjiang), it is suggested that amphibolite facies metamorphism of sedimentary sequence that deposited in a continental platform setting might favor the generation of sulfanes. Sulfanes may play an important role in the mobilization of Cr that is essential for ruby crystallization. |
