MINERAL SANDS - Earth Science

The typical mineral composition is: ilmenite 80%, zircon 10%, leucoxene 5%, rutile 1%, monazite 0.5%, others 3.5%. Rutile (TiO2) is a red to black, naturally occurring titanium dioxide with a theoretical TiO2 content of 100%, but impurities such as Fe2O3 and Cr2O2 reduce this to 93–95%.

Sand - Terminology, Composition, Shape, and More

Mar 17, 2017  Sand Composition and Shape . Most sand is made of quartz or its microcrystalline cousin chalcedony, because that common mineral is resistant to weathering. The farther from its source rock a sand is, the closer it is to pure quartz. But many "dirty" sands contain feldspar grains, tiny bits of rock (lithics), or dark minerals like ilmenite and magnetite.
