Some of the water in the area is juvenile, with magmatic water forming up to 20 % of the water.
2.
Fluorine-rich magmatic waters which leave a cooling granite may often form greisens within and adjacent to the contact of the granite.
3.
Fluid inclusion data from a number of ore deposits plot directly on the magmatic water " region " of an ? 18 O vs ? 2 H plot.
4.
The centre of the caldera was affected by resurgent doming, triggering the exposure of Miocene-age rocks ( including diorites ) . springs in the area, which contain small amounts of magmatic water.
5.
The water that issues from seafloor hydrothermal vents consists mostly of sea water drawn into the hydrothermal system close to the volcanic edifice through faults and porous sediments or volcanic strata, plus some magmatic water released by the upwelling magma.
6.
However, white smokers correspond mostly to waning stages of such hydrothermal fields, as magmatic heat sources become progressively more distant from the source ( due to magma crystallization ) and hydrothermal fluids become dominated by seawater instead of magmatic water.
7.
The H isotope composition of mantle water is around-800 ~-500 depending on its states such as fluid, hydrous phase, hydroxyl point defect, Juvenile water ( from degassing of the mantle ), magmatic water ( water equilibrated with a magma ).
8.
It was found that groundwaters substantially heated along with magmatic waters which made its way up-dip and through the intrusions in the conduit-like algal mounds which allowed the dickite to be deposited in this area and it might be conclusive to say that this trend follows elsewhere in other locations around the world.
9.
In terrestrial hydrothermal systems, the majority of water circulated within the fumarole and geyser systems is meteoric water plus ground water that has percolated down into the thermal system from the surface, but it also commonly contains some portion of metamorphic water, magmatic water, and sedimentary formational brine that is released by the magma.
