**Sample Set #5** **Metamorphic Rocks** Sedimentary rocks exposed to the effects of heat and pressure can undergo extensive chemical and physical changes. This alteration is referred to as metamorphism. Figure 4, on the next page, shows a series of layered rocks consisting of sedimentary formations that have been cut by a dike (cross-cutting planar intrusion), and, at greater depth, intruded by a batholith (large intrusion). It is in situations like this that sedimentary layers can be metamorphosed due to their proximity to hot, molten rock from which chemically active solutions are released. Near the dike, rocks which further away are limestones (114) have metamorphosed into marbles (154). Similarly, sandstones (141) have become quartzites (165). In the vicinity of the batholith, the action of heat and chemical solutions is accompanied by pressure produced by the batholith as it forces its way upward. Horizontal rock layers exposed to such pressure are folded and deformed. The result is the highly contorted layering illustrated in Figure 10. Such layering produced during metamorphism is called foliation. In such situations, rocks undergo varying degrees of metamorphism depending on their proximity to the batholith and to the intensity of deformation. Shales (112) can be metamorphosed to slates (159), schists (167), and gneiss (173) as metamorphic intensity increases. --- **FIGURE 4:** Generalized cross-section of a sequence of sedimentary rocks intruded by an igneous batholith. The layers show their original horizontal orientation away from the batholith where pressure resulting from the upward movement of the batholith is small, but near the batholith where pressures are much higher, the layering has been deformed, and is greatly contorted. The location at which different types of metamorphosed and unmetamorphosed rocks occur, along with the ID numbers of representative examples among the lab specimens, are noted in the figure by "X". **Graph/Diagram Explanation:** - The cross-section shows a batholith, a large intrusion of molten rock, beneath a sequence of sedimentary rocks. - Originally, sandstone, limestone, and shale are depicted in layers above the batholith. - A dike is shown cutting through these layers vertically. - The batholith forces pressure upward, deforming the layers, particularly near the intrusion. - Representative examples of the metamorphosed rocks are marked by
