Hydrous components in the nominally anhydrous minerals
Hydrous components in the nominally anhydrous minerals were first of significance for their impact on the mechanical strength of minerals and on the dielectric properties of synthetic materials. They are now known to influence a large number of chemical and physical properties of the host mineral and are thought to be an important contribution to the Earth’s water cycle. Detection, and concentr...
متن کاملWater in Nominally Anhydrous Crustal Minerals of Vesta
Introduction: Characterizing the abundance and distribution of water in the inner Solar System is essential for understanding the sources and timescales of water delivery to the terrestrial planets and planetesimals [1]. In this context, the Howardite-EucriteDiogenite (HED) meteorites are important to study since they are thought to originate from the asteroid Vesta [2]. These achondritic meteo...
متن کاملNominally anhydrous minerals and Earth’s deep water cycle
Deep reservoirs of water incorporated as hydroxyl into solid silicate minerals of the Earth’s interior may contain the majority of the planet’s hydrogen and have acted as buffers to maintain ocean volume and continental freeboard over geologic time. Two tenths of one weight percent H2O in subducted oceanic crustal material and subsequently released to the hydrosphere from mid-ocean ridge basalt...
متن کاملWater Content of Nominally Anhydrous Minerals in the Ibitira Eucrite
Introduction: The Ibitira eucrite is a chemically and petrologically anomalous member of the basaltic eucrite suite [1]. Chemically, Ibitira contains among the most anorthitic (calcic) plagioclase observed in eucrites and has a mean Fe/Mn ratio for low-Ca pyroxenes significantly higher than other basaltic eucrites [1]. Ibitira also slightly deviates from the mass fractionation line defined by o...
متن کاملThe unusual phases of anhydrous and hydrated pinacol.
The structure of highly twinned pinacol (2,3-dimethyl-2,3-butanediol) monohydrate, the existence of which has been known since 1922, has been determined, and the structures of anhydrous pinacol and its two other known hydrates have been reinvestigated. All the phases are unusual. The anhydrous phase is exceptional among molecular crystals in having molecules located on three different symmetry ...
