摘要
广东省已发现非烃气体（CO、N、HS、He、Ar、Rn 等）异常60余处,可分地表气苗、地下气层、水溶性气苗、水溶性气层4种。异常带在分布上与断裂带密切相关,9个异常带可归纳为 NE—NNE 向、NW 向、EW 向3组。异常的形成可能与中新生代地球去气作用有关。
Abstract
More than 60 anomalous places of non-hydrocarbon gas,including CO, N, HS,Ar,Rn etc,are discovered in Guangdong Province.The distributionof anomaly zones of non-hydrocarbon gas closely related to fracture zones.9 anomaly zones can be divided into 3 groups:NE-NNE anomaly zones;NW anomaly zones;EW anomaly zones.The gas anomalies can be divided intosurface gas seepages,underground gas beds,water-soluble gas shows and water-soluble gas beds.The formation of the anomalies may be related to degassing ofthe globe during the Meso-Cenozoic,especially in the Middle and Late Ju-rassic and the Eocene.
