Quantifying Microwear on Experimental Mistassini Quartzite Scrapers: Preliminary Results of Exploratory Research Using LSCM and Scale‐Sensitive Fractal Analysis

Abstract: Although previous use-wear studies involving quartz and quartzite have been undertaken by archaeologists, these are comparatively few in number. Moreover, there has been relatively little effort to quantify use-wear on stone tools made from quartzite. The purpose of this article is to determine the effectiveness of a measurement system, laser scanning confocal microscopy (LSCM), to document the surface roughness or texture of experimental Mistassini quartzite scrapers used on two different contact materials (f… Show more

“…Few use-wear studies have been conducted on the raw materials analysed here (e.g., Sussman, 1985Sussman, , 1988Fullagar, 1986;Knutsson 1988;Pant, 1989;Knutsson & Lindé, 1990;Pignat & Plisson, 2000;Marquéz et al, 2001;Stemp et al, 2013). A blind test was carried out to assist in interpreting the materials being worked, and the motions or actions being carried out (e.g., cutting, scraping).…”

“…The SEM has the advantage of a wider depth of field, which can allow well-focused pictures and high resolution imaging. Scanning electron microscopes are also useful for the analysis of highly reflective raw materials (for a comprehensive description of the SEM approach and its potential 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 associated with quartz-rich lithologies (Sussman, 1985(Sussman, , 1988Stemp et al, 2013).

“…El microscopio empleado es un LEXT 3100 OLS, microscopio confocal de barrido laser (LSCM), una técnica no destructiva que permite su aplicación sobre gran variedad de materiales sin preparación previa (Macdonald, 2014). En los últimos años ha aumentado su uso en aplicaciones arqueológicas (Stemp & Chung;2011;Stemp et al 2013;Ibáñez et al 2014;Reinosa et al 2015). Es un microscopio óptico, con el mismo o similar rango de aumentos en las lentes que estos microscopios, entre 2,5X y 200X.…”

“…Es aplicada a través un sistema láser enfocada sobre una parte muy concreta en el objeto de estudio desde un plano focal discontinuo (Evans & Donahue, 2008). Este microscopio registra las imágenes a través de la posición de la luz mediante un pinhole (Stemp et al, 2013), proporcionando información sobre la altura de las diferentes superficies que posteriormente se unen generando una imagen. Todos los registros de imágenes obtenidos, tanto en 2D como en 3D, van acompañados de medidas o escalas a micrómetros para facilitar la medición de determinadas zonas o variables del sector de la pieza registrado.…”
