Non-Foliation Non-foliated textures are identified by their lack of planar character. Further identification of non-foliated rocks is dependent on the composition of the minerals or components in the rock. Anthracite coal is similar to bituminous coal.
WebbMetamorphic 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. Thus, at higher temperatures it’s easier to break the ...
