In this way prehistoric studies in India, particularly the Stone Ages, had as their basis Pleistocene geology and geochronological investigations for dating the material. Thus Zeuner dated the Sabarmati industry by ‘assuming that the penultimate glaciation of the Himalayas is contemporary with that of Europe (and there is reason to believe that this is so), the age in years of the Sabarmati industry may be estimated in a very tentative way by applying either Penck’s geological dating method or the Astronomical Theory. According to either it would be of the order of 150–200,000 years’ (Zeuner, 1950, p. 44).
