Augit ist ein sehr häufig vorkommendes Mineral aus der Mineralklasse der „Silikate und Germanate“. Als Klinopyroxen kristallisiert es im monoklinen Kristallsystem mit der chemischen Zusammensetzung (Ca,Mg,Fe)2Si2O6 und entwickelt kurze bis lange, prismatische Kristalle, aber auch körnige Mineral-Aggregate von grüner, brauner oder schwarzer Farbe bei graugrüner Strichfarbe. … WebThe proportion of augite in the samples decreases from SS to OLA, while that of quartz decreases from OLA to SS. There is no augite in NCA samples, but there is a high proportion of quartz, hornblende, and olivine. NCA samples contain the highest percentage of organic matter. This result is also supported by the results obtained for LOI (Table 2).
