Contact Metamorphism occurs when magma comes in contact with an already existing body of rock. When this happens the existing rocks temperature rises and also becomes infiltrated with fluid from the magma.

WebThe crystals are generally equant (same diameter lengthwise and widthwise) and seldom exhibit foliation. Granulite forms through metamorphism of shale, greywacke, and many kinds of igneous rocks. 8. Figure 8.11: The metamorphism of shale yields certain index minerals that characterize different metamorphic grades. These minerals can be used to ... WebThe type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or …
