Abstract

Hughes (1992) raises two points in his evaluation of our paper on Hopewell obsidian studies (Hatch et al. 1990): (a) Why did we not attempt to identify the several possible western United States sources from which our Hopewell specimens were derived, and (b) was it legitimate to report hydration-rim measurements with a.1 μm or less level of accuracy? These issues are addressed within the context of our initial research goals and through reference to the literature on optical microscopy.

Resumen

Resumen

Hughes (1992) plantea dos objeciones en su exaluación de nuestro artículo sobre estudios de obsidiana Hopewell (Hatch et al. 1990): (a) porqué no intentamos identificar las posibles fuentes en el oeste de los Estados Unidos en donde nuestros especímenes fueron obtenidos, y (b) es legítimo comunicar las medidas de los hordes hidratados con un nivel de exactitud de .1 μm o menor? Se discuten estos temas en el contexto de las metas originales de nuestra investigación y a través de referencias a la literatura sobre microscopía óptica
