Il-kompożizzjoni tal-granit

Il-kompożizzjoni kimika ewlenija tal-granit hija d-diossidu tas-silikon (SiO2 >65%), u l-kontenut ta' komponenti oħra huwa relattivament żgħir (Fe2O3, FeO, MgO ġeneralment<2%,><3%). the="" mineral="" composition="" of="" granite="" is="" mainly="" silicate="" minerals,="" mainly="" quartz,="" feldspar="" and="" mica,="" among="" which="" the="" quartz="" content="" accounts="" for="" 20%="" to="" 40%.="" since="" granite="" is="" mainly="" composed="" of="" light-colored="" silicon-aluminum="" minerals,="" and="" less="" iron-magnesium="" dark-colored="" minerals,="" its="" color="" is="" mainly="" light-colored,="" but="" the="" color="" is="" darker="" with="" more="" dark-colored="" minerals.="" granite's="" mineral="" particles="" have="" larger="" crystals="" and="" similar="" particle="" sizes,="" showing="" mosaic="" and="" granular="" crystal="" structures.="" different="" types="" of="" minerals="" are="" arranged="" in="" a="" regular="" or="" irregular="">
