Formation
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.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

More about Jadeitite and Chert
Here you can know more about Jadeitite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Chert consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Chert includes Quartz, Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Chert, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Chert is available in black, brown, green, grey, red, white colors. Appearance of Jadeitite is Rough and Dull and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Jadeitite vs Chert. The hardness of Jadeitite is 3-5 and that of Chert is 6.5-7. The types of Jadeitite are Not Available whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Chert is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Chert is 0.74 kJ/Kg K.
