In a wide circle around the supply zone, the Szentgál radiolarite was more or less regularly present (='imported') in the lithic material. Occasionally, individual pieces could travel more than 500 kms from the source.
The use of silex tools did not end with the termination of the Neolithic period. They were intensively used in their original functions till the Iron Age.
