Abstract
Sri Lanka endowed with vast potential and exquisite varieties of industrial minerals. Unique physical and chemical properties of high grade quartz as a raw material for high-tech products. The characteristics of vein quartz vary with the geological environment, and although it is primarily composed of silicon dioxide, gaseous, liquid, solid trace elements can occur within crystals or between crystal boundaries.
In Sri Lanka, silica is available in two forms as free silica and combined with other elements and compounds. Quartz with extreme purity over 99 percent of Si02 is found in many parts of Sri Lanka as discordant veins and they are mainly confined to the central Highlands. Highland/Vijayan complexes boundary zone. Contain vein quartz apart of the deposits within Highland complex. The origin and provenance of vein quartz in Sri Lanka is highly a debatable aspect.
