Archaeological Significance
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.
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Jadeitite and Picrite
Here you can know more about Jadeitite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Picrite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, green, grey, white colors whereas, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Jadeitite is Rough and Dull and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Jadeitite vs Picrite. The hardness of Jadeitite is 3-5 and that of Picrite is 6.8. The types of Jadeitite are Metamorphic rock whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Picrite is white, greenish white or grey.
