Faults as secondary sources of helium

HELIUM ASSOCIATED WITH FAULTS Faults as secondary sources of helium 

Faults and fractures can act as pathways for the migration of He derived from the crust and mantle, and hence are possible secondary sources for anomalies located during exploration surveys. The potential use of He surveys to locate deep faults, and any associated mineralisation, has been discussed in the Russian literature in particular. Faults in seismically-active zones similarly act as channelways for the escape of gases, and He is one of a number of components of soil gas and groundwater that are monitored to determine whether variations in concentration can be used in the prediction of earthquakes.
