Identification of Relict Forsterite Grains in Forsterite-rich Chondrules
Introduction: Many chondrules clearly contain relict grains that result from incomplete melting of precursor material. Most discussions of relict grains have focused on grains that are easy to identify because they have compositions significantly different from their host chondrules, including forsterite in type II chondrules and dusty olivine in type I chondrules [1]. However, in order to full...
متن کاملPRÜFER SUBSTITUTIONS ON A COUPLED SYSTEM INVOLVING THE p-LAPLACIAN
In this article, we employ a modified Prüfer substitution acting on a coupled system involving one-dimensional p-Laplacian equations. The basic properties for the initial valued problem and some estimates are obtained. We also derive an analogous Sturmian theory and give a reconstruction formula for the potential function.
متن کاملSynthesis and characterization of bioactive forsterite nanopowder
Forsterite ceramic is a new bioceramic with good biocompatibility. However, the degradation rate of forsterite ceramic is extremely low, and the apatite-formation ability is also poor. On the other hand, nanostructured bioceramics are expected to have better bioactivity than coarser crystals. The aim of this work was preparation, characterization and bioactivity evaluation of forsterite nanopow...
متن کاملShock wave compression of singlecrystal forsterite
Hugoniot equation of state measurements have been performed on pure synthetic single-crystal forsterite (Mg•SiO4) in the pressure range 70-160 GPa (0.7-1.6 Mbar). These and earlier data for polycrystalline forsterite are compared with theoretical Hugoniots for the assemblages 2MgO (rocksalt) + SiO: (stishovite) and MgO (rocksalt) + MgSiO8 (perovskite). The densities attained by single-crystal f...
متن کاملShock Compression of Single - Crystal Forsterite
Dynamic compression results are reported for single-crystal forsteritc loaded along the orthorhombic a and c axes to pressures from 130 to 165 GPa. Hugoniot states for the two axes are well described by a single curve offset to densities 0.15-0.20 g/cm 3 lower than earlier data for single-crystal forsteritc shocked along the b axis above 100 GPa. Earlier data of Syono et al. [ 1981a] show margi...
