| Abstract | Helium-4, which is a product of radioactive decay in basement rocks, will preferentially migrate to the surface along deep seated faults and fractures. The discovery of such fault and fracture systems is a key element in the exploration for geothermal deposits. Helium geochemistry provides a rapid, cost effective and environmentally non-destructive exploration tool which can define concealed fracture zones. The applicability of this technique has been clearly demonstrated in regional and detailed prospect evaluations. |
