Origin and Evolution of Water in Granitic Intrusions

D/H study on lithium-bearing micas in the granitic masses from the southeastern part of China.

“…In contrast, a direct measurement by Kakiuchi (1987) for LiCl aqueous solution gives a result that the water molecules coordinated to Li+ ion are depleted in deuterium compared with free water molecules not bound to Li+ ion. As Kuroda et al (1990) discussed, the D/H fractionation factors between the systems, hydroxyl in water-undersaturated magma hydrous silicates and molecular water in super -saturated intrusion-silicates, are not the same even under the same temperature and pressure condition.…”
