Source: Webster's dictionaryPerthite is a typical texture in alkali feldspar, due to exsolution of contrasting alkali feldspar compositions during cooling of an intermediate composition. Source: Internet
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. Source: Internet
If the high temperature intermediate composition alkali feldspars are allowed to cool slowly, exsolution occurs and a perthite structure results. Source: Internet
If massive exsolution occurs when magma heads upwards during a volcanic eruption, the resulting eruption is usually explosive. Source: Internet
The sources of the stresses include deformation (e.g. an increase in pressure), exsolution, or twinning. Source: Internet
