Archaeometric study of some functional tools from the Sąspów and Wierzbica ‘Zele’ fint mines sites Jolanta Małecka-Kukawka a , Grażyna Szczepańska b , Marta Rauchfeisz b and Łukasz Kowalski a In the present work, an archaeometric approach was used to investigate a sample of the functional tools collected from the Sąspów, Cracow district, and Wierzbica ‘Zele’, Radom district, fint mines sites. Te investigated collection was completed on four non-use-worn specimens. Te presence of areas enriched in iron (Fe) compounds has been noticed on the surfaces of all the specimens. Tey were analyzed by optical microscopy (OM) and scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDS). Data sets were statisti- cally evaluated using similarity analysis (DA, CA, MDS). Te results indicated the variables that best discriminate the investigated fint artifacts collection in terms of either anthropoghenic or non-anthropoghenic nature of the residues preserved on their surfaces. KEY-WORDS: use-wear analysis, residue analysis, SEM-EDS, archaeometry, fint mining MATERIALS Te collection investigated here consist of two functional tools from the Sąspów, Cra- cow district (Dzieduszycka-Machnikowa and Lech 1976) and Wierzbica ‘Zele’, Radom district (Lech 1995: 465–480) fint mine sites and, for controlled comparison, four other non-use-worn specimens (Tab. 1 and Fig. 1). Te presence of maroon-colored stains is clearly noticeable on the working edges and surfaces of all the specimens (Fig. 2). In our preliminary opinion, there is likely to be a correlation between the stains and the iron (Fe) enriched compounds. Since such areas are present on the working edges of functional tools (K_1 and K_2) only, it provides us a basis to consider them in terms of residues; defned here as non-parent materials adhered to or incorporated on the surface of a tool (Evans and Donahue 2005: 1734).
