Hydrolytic weakening in olivine single crystals

Water distribution in the lower mantle: Implications for hydrolytic weakening

Hopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)

The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...

Shock Deformation Texture of Olivine Crystals of the Eeta79001 Shergottite

All the shergottite meteorites display intense shock metamorphisms. Especially, plagioclase shows a characteristic shock feature: formation of diaplectic glass (maskelynite) or melting (Duke, 1968; McSween and Stoffler, 1980; McSween and Jarosewich, 1983). By studying the shergottite meteorites, we can get a better understanding of the nature of shock metamorphism of olivine, in comparison with...

Supersymmetry in Single Crystals

Supersymmetry. According to the theory of unbroken supersymmetry, for each fermion there exists a boson superpartner and for each boson there exists a fermion superpartner with the same fundamental characteristics (including mass and charge). But, broken supersymmetry states that all superpartners have masses much greater than their associated particles, leaving no hope to observe the unbroken ...

Three water sites in upper mantle olivine and the role of titanium in the water weakening mechanism

[1] Infrared spectroscopy on synthetic olivines has established that there are at least four different mechanisms by which hydrogen is incorporated into the crystal structure. Two mechanisms occur in the system MgO-SiO2-H2O associated with silicon and magnesium vacancies, respectively. A third mechanism is associated with trivalent cation substitution, commonly Fe in natural olivine, while the ...
