The general inventory of the chipped stone artefacts coming from the LBK features at Apc indicates that a specific, small scale, local lithic production was conducted on-site. Majority of used raw materials are limnoquartzites (nearly 70%) originating mainly from the Mátra and Cserhát Mountains. The use of rather poor quality local raw materials influenced the technique of working raw materials, which was employed throughout the period of the functioning of LBK settlements at Apc. As a consequence, most tools were made on flakes. At the same time, as early as the oldest phase a limited supply of blade blanks and blade tools, produced elsewhere, was used. The ground stone artefacts and fragments included lower and upper grinding stones, plaquettes with polished surfaces, hammerstones, grinders/pounders. The raw materials used in the ground stone industry are either local (quartz, conglomerate, sandstone) or mesolocal (gabbro, basalt) coming from river alluvia or from the hills at the Hungarian—Slovakian border. Andesites, probably from the Mátra Mountains, occur in small quantities. Thus, the raw materials exploited at Apc demonstrate contacts with eastern region, however the site is the easternmost LBK settlement.
