Progressive metamorphism and classification

WebThe Kieffer et al. (1976) classification scheme of progressive shock metamorphism is found to apply to lunar basalts. The major shock features of the five classes that span the range 0 to 1000 kbar are described. Only three out of 152 basalt specimens show shock effects in their natural state as severe as Class 2 features. WebOct 25, 2000 · A Very Simple Metamorphic Classification.
