The main occurrence of microliths is between 1 to 1·5 m. but they do not show any typological evolution. The raw material utilized for microliths is mainly cryptocrystalline in nature, such as chert, chalcedony and quartz, though occasionally carnelian and rarely lydianite are also used. The lithic industry is based upon the production of small parallel-sided blades prepared from cores through indirect percussion by the use of bone or wooden hammer. The main stone tool types are: triangles, trapezes, lunates, asymmetrical points, borers or awls, notched and partly retouched flakes, blunted-back blades, burins, scrapers, fluted cores and macro-scrapers. The number of geometric tools and burins is small, and the percentage of reject waste material from here and allied sites is almost 90%. This indicates that the artefacts were produced at the occupation site itself.
