TRANSPORT OF NOBLE GASES FROM THE DEEP CRUST TO SHALLOW-LEVEL SYSTEMS

TRANSPORT OF NOBLE GASES FROM THE DEEP CRUST TO SHALLOW LEVEL SYSTEMS 

Release of noble gases from minerals by recoil, diffusion, fracturing or chemical change defines the amount of crustal radiogenic-nucleogenic noble gas and their relative abundance released into the proximal fluid system. The transport of the noble gases from 

The He concentration profiles expected in groundwaters for He diffusion through bulk granite (solid lines) with diffusion coefficients of 1.6 x 10 ° cm s (5 x 10 a ) assuming that
