It is water-resistant and when it splits, it breaks in straight lines with flat surface top and bottom. It allows to be cleaved into sheets since all the mica minerals of this rock are perfectly aligned at right angles to the direction of compression. Often, the changes are even more spectacular, with new minerals formed, such as garnet, mica,and tourmaline(as seen in schist). Slate is the result of the compression of shale, but is denser and retains the fissile properties, making for an interesting exercise when distinguishing between the two rocks. Slate is a metamorphic rock. Although metamorphic rocks typically form deep in the planet’s crust, … This fact-filled book describes the process that turns limestone into marble, shale into slate, and granite into gneiss. Metamorphic rocks are often used as materials for floors, roofs, and counter tops because of their beauty. Prograde: slate- PHYLLITE-schist- gneiss-migmatite (melting). Examples of foliated rocks include: gneiss, phyllite, schist, and slate. This appearance often makes it difficult to distinguish from its parent rock, shale. It differs from slate in that crystallization of micaeous minerals imparts a sheen to the rock; it differs from schist in that grains are … Slates are formed from fine-grained sediments such as mudstone and shale. Found inside – Page 11A rock may contain many different minerals . Slate is a metamorphic rock . It contains four minerals . They are quartz , feldspar , mica , and chlorite . Most foliated metamorphic rocks—slate, phyllite, schist, and gneiss—are formed during regional metamorphism. Even coal can be metamorphosed; bituminous (soft) coal, a sedimentary rock, can be changed into anthracite, or hard coal. Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Quartzite is a coarse-grained metamorphic rock derived from sandstone. Schist is a foliated metamorphic rock that is well developed and contains substantial amounts of mica. Then the clays begin to revert to the mica minerals from which they formed. Metamorphic rocks are used for roofing material, decorative gardening stone, the base for snooker tables, building material, sculpture material and paving material. Metamorphic rocks are formed when rock changes because it is subjected to different extreme conditions that have the potential to morph rocks, including high pressures and temperatures. It consists mainly of silicates (silicon and oxygen), phyllosilicates (potassium and aluminum silicate), and aluminosilicates (aluminum silicate). This particular text is written in collaboration by Drs Bradley Deline and Karen Tefend and Ms. Randa Harris with edits by Dr. Bonnie J. Robinson. Click on the image for a super-closeup.

As the rocks become heated at depth in the Earth during regional metamorphism they become ductile, which means they are relatively soft even though they are still solid. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The original rock is usually sedimentary shale, and metamorphosis progressed just far enough to fuse the sedimentary particles together. Metamorphic rocks come in three different types: slate, marble and schist. Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, … Non-foliated metamorphic rocks do not have a layered or banded appearance. Slate is formed when a sedimentary rock (shale, mudstone, or basalt) is compressed. A fine-grained, layered metamorphic rock, Slate is derived from a shale-type of sedimentary rock composed of either clay or volcanic ash. Meaning that it has been subjected to the least amount of heat and pressure (low-grade metamorphism). You will see how fine-grained slate really is.
