High grade foliated metamorphic rock

WebMetamorphic rocks are classified broadly into low, medium and high grades of metamorphic intensity, primarily due to the effects of heat on mineral stability. Heat causes atoms to vibrate; the higher the temperature, the more vibration occurs, and the weaker the bonds between atoms become. WebFoliated metamorphic rocks have elongated crystals that are oriented in a preferred direction. This forms planes of weakness, and when these rocks break, they tend to break along surfaces that parallel the orientation of the aligned minerals (Figure 10.11 ).
