It was also attempted to determine the influence of the composition of raw material on technology, during our study of Palaeolithic techniques (Jayaswal, 1972-73, pp. 64-70). For this, twelve Middle Palaeolithic industries were selected and classified within three groups on the basis of the use of raw material. These were - (1) Industries made on quartzite (rough grained rock); (2) Industries made on quartzite and minerals (rough grained and fine grained siliceous stones); and, (3) Industries consisting of tools of minerals only (fine grained siliceous rocks like chert, jasper, chalcedony etc.). The industries of Vedullachervu, Nandipalle, Vadamanu and Ramgarhwa belonged to the first group, while Mahaeo-piparia, Adamgarh, Anagwadi and Kurnool show the use of both the types of stones. The last group is formed by the industries of Tamakur, Nalgonda, Luni and Kovalli.
