There are currently hardly any references to anthracological analyses using microtomography. Expectations about its potential, suggested in part by its use on similar materials, need to be evaluated in anthracological practice, according to the specificity of its subject. This paper seeks to highlight some benefits and disadvantages of the technique in the analysis of archaeological charcoal assemblages and to point out aspects to which it offers significant contributions. Here we present the steps of an experimental plan for microtomographies acquisition applied to a set of modern reference samples of wood charcoal. A brief protocol on how to prepare contemporary charcoal samples for microtomographic imaging is also included in the proposal. Digital analysis procedures for a number of diagnostic anatomical characters used for the taxonomic identification of woods and charcoals are described below. Lastly, descriptions of the microscopic anatomy of some specimens are presented, based entirely on the analysis of virtual models obtained by microtomography. The results suggest that X-ray microtomography provides quality data for anthracology. However, time and resources needed to study large sample sets, which are the privileged basis of this disciplinary field, could interfere with its applicability. On the other hand, microtomography offers several advantages for studies based on small and/or taxonomically homogeneous assemblages of charcoals, or even specific samples. These are related to its capabilities in exploring the whole object through unlimited visualization planes, the automation of measurements and the bulk of morphological data that can be extracted from three-dimensional images, whether for index calculations or other statistical markers, the non-destructiveness involved in sample preparation and analytical processes, the preservation of physical specimens and the simultaneous documentation and storage of large amounts of available information as virtual models of the studied materials. |

La aplicación de microtomografías a los análisis antracológicos cuenta con escasas referencias por el momento. Las expectativas en torno a sus potencialidades, sugeridas en parte por su uso sobre materiales similares, precisan ser evaluadas en la práctica antracológica, en función de las características particulares de su objeto de estudio y de las problemáticas que aborda. Este trabajo busca evidenciar algunos beneficios y desventajas de la técnica en el análisis de conjuntos de carbón de madera arqueológico y señalar aspectos sobre los cuales ésta puede hacer contribuciones significativas. Se presentan aquí los pasos de un plan experimental de adquisición de microtomografías aplicado a un conjunto de muestras de referencia actuales de carbón de madera. Esta propuesta incluye además un breve protocolo para la preparación de muestras de carbón actual para la adquisición de imágenes microtomográficas. Luego, se refieren los procedimientos digitales de análisis para una serie de caracteres anatómicos diagnósticos empleados para la identificación taxonómica de maderas y carbones. Finalmente se presentan descripciones de la anatomía microscópica de algunos ejemplares realizados íntegramente a partir del análisis de los modelos virtuales obtenidos por microtomografía. Los resultados sugieren que la microtomografía de rayos X es una técnica con la que se obtienen datos de calidad para la antracología. Sin embargo, la inversión de tiempo y recursos necesarios para estudiar los grandes conjuntos de muestras que son la base privilegiada de la especialidad podrían interferir en su aplicabilidad. En casos particulares de estudios que tengan como base conjuntos reducidos, poco variables o bien ejemplares específicos, la microtomografía presenta una serie de ventajas directamente relacionadas con la posibilidad de explorar la muestra a través de infinitos planos de visualización, la automatización de las mediciones y la densidad de datos morfológicos que es posible extraer de las imágenes tridimensionales para incluir en cálculos de índices y otros marcadores estadísticos, la no destructividad de los procesos de preparación y analíticos involucrados, la preservación de los ejemplares físicos y la documentación simultánea de grandes cantidades de información almacenada y disponible en modelos virtuales de los materiales estudiados. A aplicação de microtomografias à análise antracológica tem recebido poucas referências até o momento. As expectativas sobre seu potencial, sugeridas em parte por seu uso em materiais similares, precisam ser avaliadas na prática antracológica, dependendo das características particulares de seu objeto de estudo e dos problemas que aborda. Este artigo procura destacar alguns dos benefícios e desvantagens da técnica na análise de conjuntos de carvão vegetal arqueológico e apontar aspectos para os quais ela pode fazer contribuições significativas. As etapas de um plano experimental para a aquisição de microtomografias aplicadas a um conjunto de amostras de referência de carvão vegetal de madeira contemporânea são apresentadas aqui. Essa proposta também inclui um breve protocolo para a preparação de amostras atuais de carvão vegetal para a obtenção de imagens microtomográficas. Em seguida, são discutidos os procedimentos de análise digital de vários caracteres anatômicos diagnósticos usados para a identificação taxonômica de madeiras e carvões. Por fim, são apresentadas as descrições da anatomia microscópica de alguns espécimes feitas inteiramente a partir da análise de modelos virtuais obtidos por microtomografia. Os resultados sugerem que a microtomografia de raios X é uma técnica que fornece dados de qualidade para a antracologia. Facultad de Filosofía y Humanidades.
