About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.

The choice of grain size for equivalent dose (D e) determination is governed by availability within the sample. Ideally, the grain size selected for luminescence dating should represent the modal grain size of the deposit (Roberts, 2008). Silt-sized quartz has the advantage of bleaching because of longer suspension prior to deposition.
