Focusing on the Yanzhuang chondrite, this book delves into its mineralogy and the effects of shock using advanced experimental techniques like SEM, TEM, and Raman spectroscopy. It provides a detailed analysis of the micro-structural and chemical properties of the minerals. The findings reveal that Yanzhuang is the most heavily shocked ordinary H group chondrite discovered, containing a significant amount of shock-induced melt, surpassing all other known shock-melt-bearing chondritic meteorites.
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.
