| 摘 要： | A new method of geogas (soil gas) collection and analysis, is briefly introduced. A geogas collector is buried at shallow depth to collect volatile compounds for a period of 60-90 days. The adsorbed compounds are analyzed by INAA. This paper presents the multi-elemental anomaly of a gold deposit, Southwest China.The element contents and the multielemental anomaly of geogas were compared with those in the near- surface soil around the collector, background of the collector, and in gold ores. The geogas anomaly on gold deposit is demonstrated as a direct indicator of subsurface deposits.

| Abstract: | A new method of geogas (soil gas) collection and analysis, is briefly introduced. A geogas collector is buried at shallow depth to collect volatile compounds for a period of 60-90 days. The adsorbed compounds are analyzed by INAA. This paper presents the multi-elemental anomaly of a gold deposit, Southwest China.
The element contents and the multielemental anomaly of geogas were compared with those in the near- surface soil around the collector, background of the collector, and in gold ores. The geogas anomaly on gold deposit is demonstrated as a direct indicator of subsurface deposits. |
