Abstract
This study examines one- (gas) and two-phase (aqueous solution–gas) inclusions in the calcite of the Cheremshanskian Horizon of the Bashkirian stage at a depth of 4,215–4,217 m in the Pravoberezhnaya-1 well. Homogenizing temperature is within 100–134 °C, which is likely close to the temperature of mineral formation. Calcite vein formation involves calcium bicarbonate fluid enriched in Mg chloride. It was established the calcite inclusions contain carbon dioxide, methane, and hydrogen sulfide. The gas composition of the inclusions in limestone is distiuguished of its high carbon dioxide concentration but rather low methane and hydrogen sulfide concentration.
