Silicon, Silicates and Silicosis Case Studies

Jun 17, 2020· Silicon and oxygen are by far the most abundant elements available in the Earth's crust. Minerals that have any sort of combination of silicon and oxygen are referred to as silicates and have the highest concentration in the Earth's surface. In fact, according to my Earth System Science class, silicates make up about 90% of Earth's crust mass.
