New geological data on the Transdanubian radiolarites and a revision of the so called Szentgál- complex has brought a new archaeological picture of the Bakony mountains. Earlier radiolarite subgroups such as Szentgál-type, Hárskút type or Úrkút-Eplény-type have no further relevance, because colour variation cannot be used as an indication of the exact location of the different chert outcrops. All possible colour variations, from brick-red to dark brown and varying yellowish, can be found in all parts of the Bakony mountains. Independent CRF-examinations resulted in similar observations. Such radiolarites can be found throughout the Bakony mountain range with uniform variation across the massif. Technological examination of different chopped tools from the surrounding archaeological settlements of Szentgál has provided fresh data: the settlements round Szentgál were not directly connected to the mines and to tool production. The presence of flakes, reduced cores, tablets and large volumes of waste indicate that these were not workshops preparing the mined raw material, but rather sites of regular tool production
