In all of the shocked samples (23, 33, 42 GPa), many thin veins are pervasively observed in grain boundaries and fractures of silicate. With increasing shock pressure, the number density of the vein increases. These veins are probably produced by intrusion of molten sulfide-metal into the grain boundaries and fractures in silicate at pressure release stage. In the samples shocked at 33 and 42 GPa, there appears molten texture of sulfide and metal having patched or dendritic textures (sulfide-metal melt pocket). Some chondrites have shock metamorphic textures similar to those described here. Low eutectic temperature of sulfide-metal system affects the shock metamorphism, particularly its texture., 資料番号: AA0063352012}, pages = {44--47}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Shock experiments on silicate-metal-sulfide powder mixture: Effect of low eutectic temperature of sulfide-metal system}, year = {1995} }
