“…Microwear analysis of quartzite tools has been comparatively rare in archaeology and is primarily based on the examination of wear features observed through optical light microscopes (OLM) and scanning electron microscopes (SEM) (e.g., Plisson 1984-6;Gibaja et al 2002;Clemente Conte and Gibaja Bao 2009;Lemorini et al 2014;Pedergnana et al 2016Ollé et al 2016;-for microwear analysis of *Received 23 December 2016; accepted 26 May 2017 †Corresponding author: email jstemp@keene.edu quartz tools, see also Knutsson 1988a,b;Knutsson et al 1988;Taipale et al 2014;Knutsson et al 2015).

Testing Area‐Scale Fractal Complexity (Asfc) and Laser Scanning Confocal Microscopy (LSCM) to Document and Discriminate Microwear on Experimental Quartzite Scrapers

Few microwear studies have been conducted on tools made from quartzite. Most rely on visual observation of microwear features using optical light microscopes and scanning electron microscopes. Quantification of microwear on quartzite tools is extremely rare, even though numerous methods to mathematically document surface roughness have been applied to other silicate tools. In this paper, laser scanning confocal microscopy (LSCM) was used to document surface roughness on four experimental scrapers made from two different subtypes of Mistassini quartzite that were used on either fresh or dry deer hide. Surface roughness data were analysed using area‐scale fractal complexity (Asfc). The results of this test case indicate that Asfc can effectively discriminate between the unused and used regions on the quartzite tools based on surface roughness, and that it can also discriminate between surface roughness produced by working dry versus fresh hides. Differences in the subtypes of Mistassini quartzite did affect surface roughness, but not significantly enough to prevent discrimination of the dry and fresh hide‐working tools. Although the use of the Asfc parameter for lithic microwear analysis requires further testing, these first results suggest it could be a reliable technique to mathematically document and discriminate wear patterns on archaeological quartzite tools.

“…El método traceológico sobre cuarzo y cristal de roca se comienza a desarrollar en los años 70 en aquellas regiones en las que éstos son los materiales predominantes (principalmente Escandinavia) (p. ej. Sussman 1985Sussman , 1988Knutsson 1988, etc Knutsson et al 2015). La principal dificultad para el estudio de las trazas de uso en el cuarzo es que, en general, muestran un menor desarrollo que en otros materiales como el sílex.…”

REsuMEnLos denticulados y las muescas son dos de los elementos más frecuentes en la panoplia musteriense. El creciente interés por el estudio de estos tipos permite vislumbrar su complejidad. La aparente estandarización de sus formas no lo es tal a la luz de nuevos estudios tipométricos. Así mismo, la especialización supuesta del denticulado parece encontrarse ahora en entredicho a partir de los nuevos datos revelados por estudios traceológicos que apuntan a que se trata de una pieza en esencia versátil. Presentamos en este artículo los resultados de un estudio funcional realizado sobre una muestra de denticulados y muescas en cuarzo procedente del yacimiento musteriense del Abrigo de Navalmaíllo (Pinilla del Valle, Madrid, España). Las huellas de uso sobre elementos de cuarzo son peculiares dadas las especiales características de la materia prima. Por otro lado, normalmente se conservan mejor que las formadas en materiales de mejor calidad como el sílex. Los resultados del estudio corroboran la versatilidad de dichas piezas para funciones distintas relacionadas, entre otras, con alguna de las actividades implicadas en el trabajo complejo de descuartizado y el trabajo de la madera. ABsTRACT Denticulates and notches are two of the most ubiquitous types in Mousterian industries. The increased inter-
