Aluminum is one of the big 8 elements in the Earth's crust, being the third most abundant element at about 8.1% by weight. It is a constituent of the class of silicates called feldspars, which are the most abundant minerals in the Earth's crust. It is also a constituent of mica. One aluminum silicate mineral is pyrophyllite, AlSi 2 O 5 (OH).Web
