This book introduces the unusual shock-related mineralogical features of the shocked Suizhou L6 (S5) meteorite. The olivine and pyroxene in Suizhou display a mosaic shock feature, while most of plagioclase grains have transformed to glassy maskelynite. A few of the shock-induced melt veins in the meteorite are the simplest, straightest and thinnest ones among all shock-vein-bearing meteorites, and contain the most abundant high-pressure mineral species. Among the 11 identified species, tuite, xieite, and the post-spinel CF-phase of chromite are new minerals. The meteorite experienced a peak shock pressure up to 24 GPa and temperatures of up to 1000° C. Locally developed shock veins were formed at the same pressure, but at an elevated temperature of about 2000° C that was produced by localized shear-friction stress. The rapid cooling of the extremely thin shock veins is the main reason why 11 shock-induced high-pressure mineral phases could be preserved in them so well. This book offersa helpful guide for meteoritics researchers and mineralogists and invaluable resource for specialists working in high-pressure and high-temperature mineralophysics.

This book investigates the mineralogy and shock effects of Yanzhuang chondrite, using modern micro-mineralogical experimental techniques, including SEM, TEM, EPMA, Raman microprobe spectroscopy, instrumental neutron activation analysis, X-ray micro-diffraction analysis, micro-PIXE analysis and laser ablation ICP-MS. The micro-structural and micro-morphological characteristics as well as chemical composition of minerals were studied in details. Based on the studies in the shock effects of rocks and minerals, and the detailed study in the shock-produced melt, the book concludes that Yanzhuang chondrite is the most heavily shocked ordinary H group chondrite ever found and that it contains the most abundant shock induced melt among all known shock-melt-bearing chondritic meteorites.
