A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key essential minerals a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar.read more
