There exist closed relationships between CO_(2) gas reservoir and igneous activity in Jiyang depression: ①Igneous rock directly or indirectly controls the distribution of gas reservoir. ②Igneous activity can provide gas directly, alkaline basalt igneous activity, igneous activity of Guantao stage, and lithofacies of shallow intrusive rock, subvolcanic rock and volcanic conduitare in favor of forming of gas reservoir, while eruptive face is disadvantageous. ③Roast metamorphose of intrusive body to carbonate .
Key words: Jiyang depression; Igneous activity; CO_(2) gas; Gas reservoir.
