(A) CO2-rich gas inclusions coeval with aqueous inclusions cut across overgrowths and grains of quartz; (B) CO2 gaseous inclusions are distributed along microfractures in calcite veins; (C) CH4 gaseous inclusions are linearly distributed in healed microfractures coeval in quartz; (D) CH4 gaseous inclusions are distributed in microfractures of calcite veins; (E) CO2 and CH4 inclusions are present in quartz overgrowths; (F) Hybrid CO2 and CH4 inclusions are arranged in calcite veins; (G) Pale-yellow oil inclusions are arranged in quartz overgrowths; (H) Pale-blue oil inclusions cut across multiple quartz grains; (I) Pale-blue oil inclusions are dispersed and distributed as clusters in calcite cement. All the components were identified by micro–Raman spectroscopy.
