Juvenile Water

groundwater that enters the subterranean hydrosphere from the depths of the earth for the first time. The term was proposed in 1902 by E. Seuss, who believed that juvenile water was associated with magmatic chambers, from which it was discharged into the upper parts of the crust with gaseous products.

According to current ideas, the formation of juvenile water is linked to the general processes of degasification of mantle material in the course of metamorphism and magmatism. Juvenile water reaching the crust mixes with water of different origin found there. An increased content of carbon dioxide, helium, and oxygen in groundwater is an indirect indicator of juvenile water.
