KnowraPerthiteLinked fromLinked fromThe 7 pages that link to Perthite, each with the reason it gives.All 7Broader topic 2Related 3Compared with 2FeldsparRelated: Cooling can separate an initially mixed alkali feldspar into this texture.PlagioclaseCompared with: Unlike plagioclase’s sodium–calcium series, perthite records unmixing in alkali feldspar.OrthoclaseBroader topic: Cooling can separate sodium-rich material from potassium-rich feldspar in perthitic textures.Alkali feldsparBroader topic: It is a visible record of sodium–potassium separation during cooling.MicroclineRelated: Microcline commonly hosts sodium-rich lamellae produced during cooling.Continuous reaction seriesRelated: A different feldspar phenomenon: exsolution below the solidus rather than reaction with melt.Plagioclase feldspar solid solution seriesCompared with: Perthite records broken solid solution, the failure mode the plagioclase series largely avoids.
