Relationship Of The Shell Of The Jade Surface And Internal Jade

Jade emerald is mainly produced in the Myitkyina region in northern Myanmarthe Wulu river basin, the causes and geological characteristics of the emerald deposits,Myanmar jade deposits can be divided into a primary deposit and secondary deposits,secondary deposits emerald quality is better, but in its the surface often layer and theinternal great emerald color and texture differences shell.On the basis of previous research, the use of polarized light microscopy, electronmicroprobe, X-ray diffraction, scanning electron microscopy and other advancedtesting methods, carried out a detailed study on the mineral composition of raw jadestone shell and structural characterization of the the relationship between the jadestone shell and its internal jade-depth discussions.The jade stone shell formation is mainly the result of weathering and geologicalenvironment role. The high iron content in the subtropical climate of Myanmarperidotite decomposition, a large number of Ca, Mg, Fe ion surface water into theunderground. Environment of near-surface oxidation of Fe²⁺ ions are oxidized to Fe³⁺,the formation of Fe （OH）3colloidal Fe （OH）₃colloid and jadeite mineral weatheringresidues Al₂O₃nH₂O cohesion in the clearance of mineral accumulation, theformation of aluminum bauxite and limonite colloid, and alteration of jadeite mineralcementation with the final formation of the yellow shell. After this hydration degreeof weakening of limonite colloid in water to reduce, or even into hematite, forming ared shell. Below the water table, the O₂content belongs to the weak to restore theenvironment of the upper water Ca²⁺ and Mg²⁺, of Fe²⁺ ions gathered here. The originalstone is in the environment of less O₂and of Mg²⁺ and Fe²⁺ ions. The water of Mg²⁺and Fe²⁺ ions and jadeite mineral reaction jadeite mineral alteration omphacite,amphibole, the formation of a black shell. The article also summarizes some of the special characteristics of the shell, suchas the Songhua with python, ringworm, foundry and the internal relationship of theemerald in color, transparency, and an explanation from the perspective of geology.
