Knowledge of the existence of beachrocks in Sri Lanka is very limited especially due to the limited amount of research conducted in this area. Previous Sri Lanka is famous throughout the world for the exquisite mineral varieties of very high purity. Among them vein quartz too holds prime importance. The material, generally known as quartz is primarily made of silicon and oxygen (silica-SiO2) and is considered one of the most abundant minerals found in the Earth’s crust.Quartz Industry in Sri Lanka Eng.

Geological background and Economic Minerals in Sri Lanka
Sri Lanka is rich in nonmetallic minerals such as Graphite,Vein quartz,Apatite,Dolomite ,Feldspar, Gems,Mica ,Clays,Kaolinite,Sands,Garnet sand ,Silica sand. Graphite. The use of graphite in Sri Lanka has a long history, from 1675. Sri Lankan graphite is very popular all over the world for its high purity.Beach sediments in Sri Lanka contain industrial-grade heavy mineral occurrences. Samples of both offshore and onshore sediments were collected to examine the provenance, mineralogy and geochemical compositions of the heavy mineral occurrences.
