Shocked pyroxene
Webbeen shocked. Pyroxene forms complexly zoned crystals, some of which display sector zoning. The bulk of each crystal is a subcalcic augite with an approximate composition of W 03sEnsoFS1s and a small part of each crystal is pigeonite. Pyroxenes display minor (about 15 mole% Fs) iron enrichment and are rich in © WebAs an important technology of thick coal seam mining, fully mechanized mining with a large mining height has high mining efficiency. In order to study the roof safety control of large mining height working face, the 122106 working face of Caojiatan coal mine is taken as the engineering background. The numerical simulation method is used to analyze the control …

Olivine in and around the shock melt veins or melt pockets was converted by the dynamic events in solid-state reactions to its high-pressure polymorphs or its shock-induced monomineralic melt fractionally …
Webing melt inclusions are observed. A few thin shock melt veins (<20 µm in width) are observed in our sample. The shock melt veins are composed mainly of tiny Al-rich pyroxene grains (<1 µm in size). Aggregates of stishovite and silica glass (up to 13 µm in size) and pyroxene fragments with a smooth outline are also observed in the shock melt ...
