Chris Schaller. College of Saint Benedict/Saint John's University. About 90% of the earth's crust is composed of silicate minerals. Silicates are compounds composed of silicon and oxygen; these compounds have negative charges on them. That means there are positive counterions found together with these anions. The energy gap in coesite (Iguchi-soft X-ray spectra) is 8.9 eV.
