Juvenile water is one type of underground waters that is formed by cooling of magmatic water vapor in the solid crust of the Earth. This water was first mentioned by Austrian geologist Suss, and so far no significant reservoir of this water has been reported.
Every year, due to internal and external volcanic activity, some water enters the water cycle. This water is referred to as "juvenile water" because of its first entrance into water cycle. Currently, the amount of juvenile water added to the total water available on the planet due to volcanic activity is estimated to be one tenth of one kilometer cubed. Although the amount of this water is low, but given the very important role that water plays in human life and the lack of water at the present time, more attention should be paid to it.
Deep water (or synthesized and pure) is one of those kinds of waters that originate from very great depths of the earth and can be the result of the steam of the last stage of molten magma in the earth associated with volcanic manifestations, and from those waters that have long remained between the earth's levels, and are found in some places, especially during oil drilling. Therefore, juvenile waters have deep origin, and are formed through the combination of hydrogen and oxygen and with the hardening of Inner and outer melting materials. These waters are often the primary producers of deep warm mineral water.
