Helium Isotopes
Helium gas is a trace constituent of groundwater and thermal fluids, and the ratio of 3He to 4He can be measured with a high-precision mass spectrometer to determine whether it is derived from air, from the radioactive decay of uranium and thorium in the crust, or from the mantle. The latter is a characteristic feature of volcanic and geothermal gases.
