摘　　要：Geogas prospecting is a new method in the search for deep and/or concealed mineral deposits.The probing depth of the method comes to 300-500 m below the surface. The method, based on nuclear aualysis and accumulation sampling, has matured and become useful method of geogas prospecting, through authors' studies more than 10 years. The study of the mechanism for geogas prospecting has also been progressed. It bas been revealed that the geogas matter is in the form of nano-scale particles of the ores by the observation of scanning electron microscope (SEM). This paper summarizes the feature of the geogas anomaly, and describes its forming mechanism. A new example using geogas prospecting is given.Geogas prospecting is a new method in the search for deep and/or concealed mineral deposits.The probing depth of the method comes to 300-500 m below the surface.
