The genetic features of quartz sands and quartzites of Oman are determined. It is established that, along with coastal-marine, there are also delta varieties of quartz sand and quartzite.
The various forms of crystalline silica are: α-quartz, β-quartz, α-tridymite, β-tridymite, α-cristobalite, β-cristobalite, keatite, coesite, stishovite, and moganite (NIOSH, 2002). The most abundant form of silica is α-quartz, and the term quartz is often used in place of the general term crystalline silica (NIOSH, 2002).
