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.
The topographical position and size of the site, the number of detected houses, the presence of the early phase make the Apc-Berekalja I settlement one of the most significant sites of the LBK in Hungary. The ongoing processing of the excavation data provided already some very important observations. The geoarchaeological results demonstrated the presence of the in situ soil of the Neolithic period and effects of floods on the settlement. The study of the chipped and ground stone material coming from the Neolithic features revealed no conspicuous changes in the lithic industry of the settlement from the pre-Notenkopf to Želiezovce phases of the LBK. Lithic raw materials came exclusively from territories to the east of the site, which is an evidence of the isolation of the LBK groups that inhabited Apc.
