二氧化碳地质研究具有重要的资源意义和地学意义。其资源意义表现在高纯CO₂天然气可视为珍贵的矿产资源,在工农业中有广阔的用途。CO₂地质研究的其它地学意义在于它是全球碳循环过程中的重要中枢,也是人类认识自然的极好指标。全球高含CO₂天然气的分布具有明显的区域性特点,主要分布在北美洛基山东麓、中国东部、南中国海、南澳大利亚和新西兰,等环太平洋国家和地区,还有欧洲喀尔巴阡地区和高加索地区。这些地区正好是中—新生代火山—岩浆活动激烈、构造十分发育、地热流值异常高的含烃或高含碳酸盐物质的沉积盆地。

Studying of carbon dioxide (CO₂) is of significance for researching CO₂ as a sort of resource and further studying geoscience.High pure CO₂ percentage gas looks upon with a kind of resource,which has many uses.CO₂ is the most important media of the global carbon cycle,and the best target of studying nature.The global distribution of high CO₂ gas,which shows clear province,is found in many areas of circum-Pacific (for examples,the easter of the Rocky Moutain,the eastern of China,the South Sea of China,the South of Australia and New Zealand),the Carpathien and the Caucasus etc. There are many Mesozoic-Cenozoic sedimentary basins developing much volcanomagmatism, tectonics and abnormal high temperature and containing hydrocarbon and significant carbonate material in these areas.
