Abstract

Cortex is often used as an indicator of core reduction and transport, but current measures to evaluate the observed amount of cortex in a lithic assemblage with what might be expected under particular conditions are still ambiguous. The purpose of the present study is to develop and evaluate an alternative method based on solid geometry. This method is evaluated with an experimentally produced assemblage, and implications of its application to archaeological assemblages are presented and discussed. /// La corteza se utiliza a menudo como indicador de la reducción del núcleo y el transporte de lítica. Sin embargo, las medidas actuales para evaluar la cantidad de corteza en un conjunto lítico contra lo que se pudiera esperar bajo ciertas condiciones siguen siendo ambiguas. El propósito del presente estudio es desarrollar y evaluar un método alternativo basado en geometría sólida. Este método se evalúa con un ensamble producido experimentalmente. Las implicaciones de su uso en conjuntos arqueológicos se presentan y se discuten.
