What is jade jade? Jade jade is a dense block-like aggregate formed by the interlacing of numerous fine fibrous mineral crystallites mainly composed of jadeite. There are four main points of view for the formation of jadeite in nature:
The first view is considered to be the desiliconization product of the residual granite slurry that the magma invaded into the ultrabasic rock under high pressure conditions.
The second view is that the formation of primary albite into jadeite during regional metamorphism is formed; or it is believed that under the action of compressive torsional stress and low temperature caused by plate collision, albite first forms a blue flash with a lower degree of metamorphism. The stone schist is further transformed into jadeite.
The third viewpoint is that the granite veins and the pale-colored gabbro-type veins are replaced by a hot aqueous solution with a high chemical potential of sodium at a pressure of 12 to 14 kPa.
The fourth viewpoint is based on the discovery of three-phase inclusions of water-methane to jadeite in jadeite. It is believed that jadeite is crystallized from a near-hard jade silicate melt. It is believed that this kind of melt originates widely in the mantle of 300-400 km. Containing an alkali pyroxene layer.
