Definition
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
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains

Formation
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Slate and Jadeitite
Here you can know more about Slate and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Slate and Jadeitite consists of mineral content and compound content. The mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Slate vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Slate is Dull and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Slate vs Jadeitite. The hardness of Slate is 3-4 and that of Jadeitite is 3-5. The types of Slate are Not Available whereas types of Jadeitite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Slate is light to dark brown while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Slate is 0.76 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Slate is heat resistant, impact resistant, pressure resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
