WebUnder dynamothermal (regional) metamorphism, however, complex mineralogical changes are associated with development of foliation, crushing and granulation of mineralogical constituents. Rocks like gneisses and schists of great variety are produced. Hornblende schists and amphibolites are a few important examples. 2. WebJul 22, 2024 · Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call “mud .”. This composition places shale in a category of sedimentary rocks known as “mudstones.”. Shale is distinguished from other mudstones because it is fissile and laminated.
WebCharlene Estrada. Fig. 3.7.1. Limestone and chert layers of rock that have been folded at high temperatures and pressures due to metamorphism. The word “Metamorphic” is Greek: meta means change and morphos means form. When rock units are buried very deeply within Earth’s. crust. , they are subjected to high temperatures and pressures. 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 …

Metamorphic rocks, and the processes that create them, are key parts of the rock cycle that relates igneous, sedimentary, and metamorphic rocks. Most metamorphic rocks form when heat, pressure, or chemically reactive fluids cause changes in preexisting rocks (Figure 8.2).
