Definition
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains

Archaeological Significance
Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
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 Gossan and Jadeitite
Here you can know more about Gossan and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Jadeitite consists of mineral content and compound content. The mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, 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 Gossan vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Gossan is available in brown, brown- black, gold, green, rust colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Gossan is Dull and Banded and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Gossan vs Jadeitite. The hardness of Gossan is 4-5 and that of Jadeitite is 3-5. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Jadeitite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gossan is white to grey while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Gossan is 0.24 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.Gossan is heat resistant, impact resistant, pressure resistant whereas Jadeitite is heat resistant, water resistant.
