A total of 29 groups of isotope age data such as Sr-Nd isotope age data and Nd model age data of igneous rocks, including granites, volcanic rocks, dyke swarms, cumulates, and ophiolites, formed in different periods of time are reported in this paper, which show the following two features:(1) igneous rocks including ophiolites formed in this area since 800 Ma BP all have high eNd and low Sri, with most Sri values centered in the range of 0.7045 to 0.7060 and eNd values in the range of 1 to 5, and (2) most of the TDM ages are in the range of 800 to 600 Ma, with only a few at 1000 Ma.

By research for deep faults and igneous rocks related to CO2 gas fields, the author considers that magma is the carrier for CO2 gas migration, while the development of igneous rocks is an important sign of the synchronous fault spatio-temporal activity. The 'migration' is one of the most important elements for mantle source CO2 gas accumulation, which means that there are deep faults connected to the mantle, directly or indirectly, and fault activity must be consistent with CO2 gas migration in space and time.
