Fascinating Fact The oldest rock is the Acasta gneiss (3.96 billion years old). Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form”. The protoliths for pelitic rocks are shales (aluminous rocks), not sandstones (quartzofeldspathic rocks) Here are the stability fields of common pelitic minerals: the presence of andalusite VI Al V AlSiO 5 implies low P metamorphism Erosion The wearing away and smoothing of rocks as they are transported. *��x����*5-����i,W�K~�o�@@w �'@@�u Metamorphic rocks may be classified on the basis of foliation into two types. , , , and . • Facies represent specific temperature - pressure regimes. h޴Yے۸}�W���J�0$x�JR�];�l���X�}��G�$ڼ�ie^��9 �7��ӧO7�/��l�8,�[ũ�Ә5r�+���������0��"�=p�[�2�������a�x\���z��\�a.��'!�F, The water itself may have also come from sources like the sea and been heated by an igneous source.
