Metamorphic Rocks Checkpoint A metaphoric rock is the transformation of an existing rock and comes from the sedimentary rocks sandstone, shale, basalt which is an igneous rock and limestone. These rocks are subject to heat pressure that will cause physical and chemical change within the rocks. Metaphoric rocks have to come from the rocks that are the most abundant. These rocks are formed through heat buildup within sedimentary and igneous rocks. This built up pressure causes them to sedimentary and igneous rocks to change and morph into a metamorphic rock. The two categories of metaphoric rocks are foliated and non-foliated. The rocks that are foliated have a

Non-foliated rocks are different from foliated because they do not have a pattern that shows strain. An example of a non-foliated rock could be marble.
