25.. Dillehay& Rossen:Nanchoclithic Traditionof differing terminology and, despite this, thetool iswell..understoodin terms offunction anduse. Poor agreement means that substantialdifferences were found in the results of the twoanalyses, and the meaning of these differenceswill be discussed below.This systemwasmodifiedfrom a similaranaly..sis comparison developed by Dillehay for usewith the Monte Verde lithic collections fromsouthern Chile.Table 15: Summary of imeranalysis agreement of tool/unctionsTooltypeForm1 largequadrilateral2 mediumquadrilateral3 smallquadrilateral4 largesemi-lunar5 mediumsemi-lunar67smallsemi-lunarthicksemi-lunar8 burinmulti9 burinsimple10 largecore12 pentagonal13 incurved14 unmodifiedutil15 blocky1"6 thick rectangular17 thickpentagonal18 smalltriangular1920mediumtriangularlargetriangular21 amorphous125 amorphous226 largehandledtyposlice/cutslice/cutslice/cutslice/cutslice/cutslice/cutcuttingboringboringscraping!planing,hoeingslice/c~tplaningslice/cutscraping!planingcuttingcuttingslice/cutslice/cutslice/cutscraping!planingAction Material use Agreementmicroslice/cutslice/cutindeterminatesawingsawingscrapingvariousboringslice/cutvariousslice/cut,scrapingslice/cut,scrapingvariousvariousslice/cut,scrapingslice/cut(hafted)indeterminateslice/cutslice/cutwoodwoodwoodwoodmicrosoftplantsoftplantmed.-to-hardbonesoft,soft-med.softplantsoft'to-med.varioussoftplantvarioussoftplan~various.variousvariousvariousindeterminatesoftsoftwoodgoodgoodfairfairpoorpoorgoodpoorgoodgoodfairfairgoodgoodfairIn considering the ramificationsofT able 15,it is important to remember the smallsample ofmicroscopic analysis specimens, with toolscharacterized for the sake of general discussionbased on only one to five specimens per type.With this major caveat, it is thus encouragingthat seven tool types were classified.as havinggood agreement, six as having fair agreement,and only three as having poor agreement be..~een the two formsof analysis.In severalcases,the microscopic use..wear analysis confirmed thecategorizations made from typological data.Quadrilateral forms with low edge angles,suchas Types 1 and 2, were confirmed as plantcutters. The Type 8 faceted burin..likepointedform was indeed used for boring. The characterizationsof Types 12and 17,both pentagonalforms with medium edge angle modes andtrends, as general purpose plant cutters werewell..establishedby analysis agreement.
