Slate Facts Slate is a metamorphic rock that forms from mudstone or shale. The mudstone or shale normally contains clay or volcanic ash. Slate is unique in that it does not require any type of cementation to hold its particles together.It has a very attractive appearance and it is also durable. Interesting Slate Facts:halk boards are made of slate and chalk is made of limestone, another type of rock. Slate is used to make turkey calls which are devices that mimic the sound of different turkeys and used by hunters. Slate has a wet-like appearance when exposed to the sun.

Types of Metamorphic Rocks Slate is a low-grade metamorphic rock, with a dull luster and strong cleavage. It is derived from shale by regional metamorphism. (more below). Slate forms when shale, which consists of clay minerals, is put under pressure with temperatures of a few hundred degrees or so.

- Slate belongs to Metamorphic Rocks while Basalt belongs to Igneous Rocks. Texture of a rock refers to the grain size and shape of grains, the relationship between neighbouring grains and the orientation of grains within the rock.

Metamorphic rock Quartzite, a form of metamorphic rock, from the Museum of Geology at University of Tartu collection. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means change in form.or example, slate is a foliated metamorphic rock, originating from shale. Non-foliated rock does not have planar patterns of strain. Rocks that were subjected to uniform pressure from all sides, or those that lack minerals with distinctive growth habits, will not be foliated.

Slate Slate Macro (~ 6 cm long and ~ 4 cm high). Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism.It is the finest grained foliated metamorphic rock.late is not to be confused with shale, from which it may be formed, or schist. The word slate is also used for certain types of object made from slate rock.

- Kinds of Metamorphic Rocks. 1  Slate - low grade metamorphosed shale; very fine grained; slaty cleavage should not be confused with bedding planes. 2  Phyllite - next step up from slate, larger mica grains give the rock a luster.  Schist - a strongly foliated rock with large grains of platy minerals.

Chapter 10 - Metamorphic Rocks and Processes Below are descriptions of the most common metamorphic rocks with their protoliths. Slate is a fine-grained gray, green, or bluish metamorphic rock easily split into smooth, flat plates along cleavage planes. Slate is used for roof shingles and black boards. Slate displays slaty rock cleavage (see below).

Slate In the coal mining industry of the Appalachian Basin, the word slate is still used by many miners to in reference to the shale that forms the roof and floor of a mine and for fragments of shale that are separated from the coal in preparation plants.late can also contain abundant quartz and small amounts of feldspar, calcite, pyrite, hematite and other minerals. Most slates are gray in color and range in a continuum of shades from light to dark gray. Slate also occurs in shades of green, red, black, purple and brown.

Slate Slate. Slate is a very fine-grained metamorphic rock form composed of minute mica flakes. It shows excellent rock cleavage and has found many uses for its uniform flat plates. It has been extensively used for roof and floor tiles.It has been used for blackboards and is the standard material for the beds of pool tables.late is a very fine-grained metamorphic rock form composed of minute mica flakes.

- Marble is a metamorphic rock that is formed from the sedimentary rock limestone. Quartzite is a metamorphic rock that is formed from the sedimentary rock sandstone. Slate is a metamorphic rock that is formed from the sedimentary rock mudstone.Granulite is a metamorphic rock that is formed from the igneous rock basalt. Learn about sedimentary rocks, igneous rocks, other rocks and minerals or fossils. Make a fossil cast or check out our rock sorting lesson plan.plift and erosion help bring metamorphic rock to the Earth's surface. Examples of metamorphic rocks include anthracite, quartzite, marble, slate, granulite, gneiss and schist. Anthracite is a type of coal with a high carbon count, few impurities and with a high luster (meaning it looks shiny).

slate and tile A ‘slate tile’ is a piece of slate cut and prepared for use as a tile. Tiles, for covering surfaces such as roofs, walls and floors, are made from a variety of hard-wearing materials. These include natural slate, fired clay and concrete. Slate is a fine-grained metamorphic rock that can be split easily into thin layers.

slate and shale Slate. Jonathan Zander. Formed millions of years ago, slate and shale rocks have served as important materials throughout human history. Slate has been used in construction and household items, while shale contains petroleum and other minerals that can be extracted for commercial use. Scientists have determined that most slates were originally clay sediments deposited by water.

- Marble is another example of a metamorphic rock. It is formed from limestone. Metamorphic rocks sometimes contain fossils if they were formed from a sedimentary rock, but the fossils are usually squashed out of shape.

slate slate. 1. a fine-grained rock formed by the metamorphosis of clay, shale, etc., that tends to split along parallel cleavage planes, usu. at an angle to the planes of stratification. 2. a thin piece or plate of this rock or a similar material, used esp. for roofing or as a writing surface.3. a dull, dark bluish gray.. (Geological Science). a. a compact fine-grained metamorphic rock formed by the effects of heat and pressure on shale. It can be split into thin layers along natural cleavage planes and is used as a roofing and paving material. b. (as modifier): a slate tile.

What rock is formed when shale is transformed to metamorphic rock? Slate is the metamorphic rock formed from shale. A pile of mud can turn into shale (a fine-grained sedimentary rock) with relatively low pressure, about 3 mi (5 km) down into the earth. With more pressure and some heat, shale can transform into slate. Metamorphic rock found closer to Earth's surfac….
