Examination of High Temperature Annealing of Amoeboid Olivine Aggregates: Heating Experiments of Forsterite and Anorthite Mixtures
Introduction: Amoeboid Olivine Aggregates (AOAs) are irregularly-shaped, 100 µm to 5 mm in size, fine-grained objects that constitute a few vol% of meteorites in most carbonaceous chondrite groups. Previous studies concluded that AOAs are aggregates of solar nebula condensates which continued to react with the solar nebula vapor to the temperature to form phyllosilicates. However, these studies...
متن کاملMesoscale Simulation of Grain Boundary Diffusion Creep in the Presence of Grain Growth
Grain-boundary (GB) diffusion creep (Coble creep) is the dominant deformation mechanism for the fine-grained materials under low stress and at elevated temperature [1]. From the classical Coble creep formula [1], the strain rate is proportional to the external stress, and inversely proportional to the cube of the grain size: 3 ~ − d σ ε& . During creep deformation the grains become elongated in...

15 صفحه اولRelationship between topological order and glass forming ability in densely packed enstatite and forsterite composition glasses.
The atomic structures of magnesium silicate melts are key to understanding processes related to the evolution of the Earth's mantle and represent precursors to the formation of most igneous rocks. Magnesium silicate compositions also represent a major component of many glass ceramics, and depending on their composition can span the entire fragility range of glass formation. The silica rich enst...
