exsolution उदाहरण वाक्य

The sources of the stresses include deformation ( e . g . an increase in pressure ), exsolution, or twinning.
While slowly cooling within the earth, sodium-rich albite lamellae form by exsolution, enriching the remaining orthoclase with potassium.
It results from exsolution from chalcopyrite at temperatures below 200 to 210 �C . It has also been reported from carbonaceous chondrite meteorites.
The intergrowth forms by exsolution due to cooling of a grain of alkali feldspar with a composition intermediate between K-feldspar and albite.
The mineral occurs as exsolution lamellae and particles in rutile, coexisting with kyanite, sillimanite, and tourmaline in a highly metamorphosed gneiss.

This coexistence may result in exsolution lamellae in cooled ilmenites with more iron in the system than can be homogeneously accommodated in the crystal lattice.
Bararite has no known solution or exsolution, but it is always mixed with other substances ( cryptohalite, sal ammoniac, and sulfur ).
If the latter subgroup cools slowly from a melt, it forms exsolution lamellae because the two components orthoclase and albite are unstable in solid solution.
Slow cooling allots the calcium the necessary time to separate itself from the structure to form exsolution lamellae of calcic clinopyroxene, leaving no pigeonite present.
