Many hydrogen and oxygen isotopic studies have shown that the ore fluids associated with porphyry copper-molybdenum deposits are mainly from magmatic water
or the mixing of magma and meteoric water to varying degrees and that in the late-mineralization stage, meteoric water may seep extensively into the hydrothermal system [27-29].
The study, titled "Giant magmatic water
reservoirs at mid-crustal depth inferred from electrical conductivity and the growth of the continental crust," was published in the journal (http://www.sciencedirect.com/science/article/pii/S0012821X16305805) Earth and Planetary Science Letters.
In the Hydrogen and Oxygen isotopic diagram, the plotted points of the Linglong granite and Guojialing granodiorite samples are partly located in the usual range of magmatic water
. However, another part of the plotted points is close to the range of water in the mantle, which implies that there may be some mantle materials participated in the process of granites diagenesis.
Using Chandrayaan's data, the National Aeronautics and Space Administration (Nasa) of the US detected magmatic water
locked under the surface of the Moon.
"Using data from NASA's Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organisation's Chandrayn-1 spacecraft, scientists remotely detected magmatic water
, or water that originates from deep within the moon's interior, on the surface of the moon," the space agency said in a statement.
TEHRAN (FNA)- Scientists have detected magmatic water
-- water that originates from deep within the Moon's interior -- on the surface of the Moon.
The [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] values calculated for the Huntington Mountain alteration assemblages certainly do not reveal any strong association with magmatic water
was tied up in biotite and hornblende which had formed earlier.
Values of dD for Stage 1 quartz are lighter than those for magmatic water
(-50 [per thousand] to -80 [per thousand])  and when paired with calculated [[delta].sup.18] [O.sub.H2O] values, they plot under the magmatic water
box on a [delta]D versus [[delta].sup.18] [O.sub.H2O] diagram (Figure 11).
Common sources of fluids that typically form ore deposits are magmatic water
, meteoric (rain) water, sea water, and connate or formation water.
The oxygen isotopic compositions of the early and middle stages ore-forming fluids of the Liyuan deposit are similar to those of magmatic water
or metamorphic water, but the hydrogen isotopes plot slightly below the magmatic water
or metamorphic water fields, and the late stage fluids show both lower oxygen and hydrogen isotopic compositions than the magmatic water
or metamorphic water in the [delta]D vs [delta][sup.18]O diagram (Figure 12).
The abundance of analcime in the rocks toward the top of the intrusion indicates significant retention of magmatic water
