Sulfur-containing gases in the inclusions are represented by CS 2 (0.004–0.074 rel.% in all samples), COS (0.003–0.008 rel.% in all minerals, except for antlerite), H 2 S (0.002–0.008 rel.% in all minerals, except for copiapite, Table 3 , Fig. 8 ). In addition, we identified (rel.%): methylthiophenes...
