Serpentinization is a widely observed hydration process in the earth’s crust. In this study, hydrothermal experiments were performed at different temperatures, times, and pH values to explore geochemical processes of serpentinization forsterite. The results indicated that forsterite converts serpentine after reacting with SiO2 200 °C 13 for 20 days system. X-ray diffraction patterns showed liza...

Introduction: Magnesian silicates such as for-sterite (Mg 2 SiO 4) and enstatite (MgSiO 3) are major minerals in universe including disks around young stars [e.g., 1], shells around evolved stars, in particular, oxygen rich stars [e.g., 2, 3] and so on. It is thus important to understand evaporation and condensation behaviors of magnesian silicates, which are major phase-transformation reaction...

Chondrites are the likely building blocks of Earth, and identifying group chondrite that best represents Earth is a key to resolving state early Earth. The origin chondrites, however, remains controversial partly because their puzzling major element compositions, some exhibiting depletion in Al, Ca, Mg. Based on new thermochemical evolution model protoplanetary disks, we show planetesimals with...

This work is designed to focus on the glassy network analysis and visualizing cluster subnets formation, rich set of bond-, edge- face-sharing linkages. The correlation between degree polymerization linkages forming apparently indicated. distribution SiOx clusters computed determine characteristic Mg-rich region. BOs, NBOs FOs also are investigated prove behavior Mg2+ incorporating into -Si-O- ...
