“…Metallurgy reached Mesoamerica in current Mexico in relatively late times, yet this happened when the techniques and results were already of higher quality (LARA, 2006: 3-5). In the case of Mexico, the treasure found in an ancient tomb in Monte Albán, Oaxaca, represents a worldwide known example of metallurgical dexterity (CAMACHO-BRAGADO et al, 2005).…”

Arqueometria é a aplicação de técnicas em Ciências Naturais, incluindo a Geografia, para resolver problemas de Arqueologia e Conservação do Patrimônio. A corrosão constitui o principal processo de deterioração dos metais, desencadeado pelas propriedades da matriz circundante. Este trabalho enfoca a corrosão atmosférica em Oaxaca, México. Os métodos incluem a criação de estações de corrosão atmosférica para a técnica de perda de peso e a geolocalização do patrimônio arqueometalúrgico na área estudada. Uma breve revisão histórica da importância cultural dos metais no México também está incluída. Os resultados dos três primeiros meses de medição mostram que os valores de corrosão atmosférica são mais altos no centro da cidade, onde o patrimônio é mais concentrado. A poluição do ar e o aumento da temperatura atribuídos ao aquecimento global podem ser relevantes para explicar os dados obtidos. Uma análise mais aprofundada de um ciclo completo do ano pode reforçar essa tendência. O método mostrado se torna uma ferramenta útil de gestão patrimonial e urbana e é aplicável a outros espaços geográficos.

Bells of copper and copper alloys and gold–copper alloys were deposited in events at the Cenote Sagrado at Chichén Itzá, Mexico during the site's primary occupation (ad 750–1050) and in later centuries. Housed in three museums in the United States and Mexico, bells (n = 38) were evaluated for traces of fabrication and alteration using Vis–UV–IR optical microscopy. Bulk compositions were determined through p‐ED‐XRF. Phases and compositional variation by depth were characterized through XRD and RBS. The technological styles of bell groups were ascribed to communities of metallurgical practice, from West and Central Mexico to Costa Rica and Panama.

“…In the case of this collection, few electron microscope analyses (SEM-EDS) were carried out on a small number of samples from selected items. [47] Recently, a set of portable equipments were transported to the Museo de las Culturas de Oaxaca in Oaxaca City to perform a non-destructive and non-invasive characterization. The state of conservation of the collection is very good.…”

“…Certainly, the richest and most important collection with an archaeological context from Mesoamerica is the Tomb 7 from Monte Alban, central Oaxaca in the South of Mexico, corresponding to the Mixtec Culture of the late postclassic period (1200–1521 A.D.). In the case of this collection, few electron microscope analyses (SEM‐EDS) were carried out on a small number of samples from selected items 47. Recently, a set of portable equipments were transported to the Museo de las Culturas de Oaxaca in Oaxaca City to perform a non‐destructive and non‐invasive characterization.…”

SANDRA: a portable XRF system for the study of Mexican cultural heritage

Destructive Analysis using X-rays) developed at the Physics Institute of the UNAM, Mexico, for the study of Mexican cultural heritage collections. The X-ray fluorescence (XRF) SANDRA device can use 75 W Mo, Rh and W X-ray tubes and Amptek Si-PIN and Cd-Te detectors that are selected and combined depending on the elemental range detection requirements and the specific problem to be studied. In this paper, a full description and characterization of this system, sensitivities for the X-ray tubes and detectors as well as the detection limits are discussed. Examples of applications to technological studies on pre-Columbian metallic artifacts and analysis of color materials of ancient Mexican codex are shown.
