WEITZEL, Celeste; BORRAZZO, Karen; CERASO, Antonio  e  BALIRAN, Catalina. Trampling Fragmentation Potential of lithic artifacts: an experimental approach. Intersecciones antropol. [online]. 2014, vol.15, suppl.1, pp.97-110. ISSN 1850-373X.

A proposal to estimate the Trampling Fragmentation Potential (TFP) on lithic artifacts from their metric attributes is presented. We apply a data mining technique known as decision tree to experimental datasets obtained in several trampling experiments. Results show that the ratio of area to thickness is the main element affecting the probability of breakage on lithic artifacts by trampling. Also, a maximum thickness value for lithic artifacts prone to be broken by trampling is estimated. Finally, we argue establishing threshold values for trampling potential allows distinguishing incidental fractures with similar traits and different origins.
