It takes high polish and is often used for sculpture and as building material. Foliated metamorphic rocks such as gneiss , phyllite , schist , and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
Other examples include quartzite, hornfels, and novaculite. It is composed primarily of quartz. Non-foliated metamorphic rocks do not have a platy or sheet-like structure. The specimen shown above is a "chlorite schist" because it contains a significant amount of chlorite.
It is composed primarily of calcium carbonate. Some rocks, such as limestone are made of minerals that are not flat or elongate. Metamorphic rocks Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.
Metamorphic rocks are often squished, smeared out, and folded. Information about ore minerals, gem materials and rock-forming minerals.
It is also a highly dense, soft, and heat resistant rock with high heat capacity. Soapstone is a metamorphic rock that consists primarily of talc with varying amounts of other minerals such as micas, chlorite , amphiboles, pyroxenes, and carbonates. What is a Sand Dune: What is regional metamorphism?
Water Erosion: It is produced by contact metamorphism. The specimen shown above is about three inches across. It is a soft, dense, heat-resistant rock that has a high specific heat capacity.
Sonia Madaan. Seeing and handling the rocks will help you understand their composition and texture much better than reading about them on a website or in a book.
Here is a list of the most known types of metamorphic rocks. It is a low-grade metamorphic rock that splits into thin pieces. The Rock Used to Make Beer.
