Definition
Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains

Formation
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.
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 Porphyry and Jadeitite
Here you can know more about Porphyry and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Porphyry and Jadeitite consists of mineral content and compound content. The mineral content of Porphyry includes Biotite, Chert, Feldspar, Garnet, Graphite, Quartz, Silica and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Porphyry vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Porphyry is available in black, brown, colourless, green, grey, red, rust, white colors whereas, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Porphyry is Dull and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Porphyry vs Jadeitite. The hardness of Porphyry is 6-7 and that of Jadeitite is 3-5. The types of Porphyry are Rhomb Porphyry 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 Porphyry is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Porphyry is Not Available 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.Porphyry is heat resistant, impact resistant whereas Jadeitite is heat resistant, water resistant.
