magmatic water

This magmatic water is released to the atmosphere during a volcanic eruption.

Locked in mineral grains, this magmatic water is thought to have originated from an unknown source deep below the surface of the moon.

Magmatic water rises from great depth accompanying magma intrusion and affects mineralogy.

The internal magmatic water provides information about the Moon's volcanic processes and internal composition, Klima said.

Fluorine-rich magmatic waters which leave a cooling granite may often form greisens within and adjacent to the contact of the granite.

Any magmatic waters in these hydrothermal solutions must have been swamped by the circulating meteoric groundwaters of the environment.

Non-meteoric forms of groundwater are connate water and magmatic water, also termed juvenile water.

Magmatic water may also be released as hydrothermal fluids during the late stages of magmatic crystallization or solidification within the Earth's crust.

However, estimation of pre-eruptive magmatic water fugacities is possible in samples which contain phase assemblages which are sensitive to water fugacity.

The crystallization of hydroxyl bearing amphibole and mica minerals acts to contain part of the magmatic water within a solidified igneous rock.

Fluid inclusion data from a number of ore deposits plot directly on the magmatic water region of an δO vs δH plot.

The oxygen, carbon, and hydrogen isotopic values indicate that in the early stages of mineralization, magmatic water and carbon from a magmatic source were predominant.

Ultimate sources of this magmatic water includes water and hydrous minerals in rocks melted during subduction as well as primordial water brought up from the deep mantle.

Magmatic water or juvenile water is water that exists within, and in equilibrium with, a magma or water-rich volatile fluids that are derived from a magma.

The M3 instrument discovered evidence of magmatic water locked in mineral grains on the surface of the moon, having imaged the lunar impact crater Bullialdus, which lies near the lunar equator.

LS fluids are a mixture of rainwater that has percolated into the subsurface and magmatic water (derived from a molten rock source deeper in the earth) that has risen toward the surface.

"This internal magmatic water also provides clues about the moon's volcanic processes and internal composition, which helps us address questions about how the moon formed, and how magmatic processes changed as it cooled," she added.

'Magmatic water' - liquid that originates from within the moon's interior - was detected by Nasa's Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organization's Chandrayaan-1 spacecraft for the first time from lunar orbit.

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.

"This surficial water unfortunately did not give us any information about the magmatic water that exists deeper within the lunar crust and mantle, but we were able to identify the rock types in and around Bullialdus crater," said co-author Justin Hagerty, of the U.S. Geological Survey.
