description Soil micromorphology is a technique used in archaeology to study undisturbed samples and allows to visualize the elements of a soil and to understand the pedological evolution of the parent material by observing its composition, organization, and pedofeatures –soil horizon’s characteristics derived from specific pedogenic processes–. We present the results of the micromorphological analysis carried out on soil samples coming from three archaeological sites of the Salado River Depression (Buenos Aires province): San Ramón 7 (SR7), in a wetland environment, Laguna Esquivel Fagoada (LEF), and Laguna Del Medio, close to shallow lakes. This study aims to identify site formation processes that could have affected the preservation of buried archaeological materials. Results indicate that the soils in each of the sites considered are different and have been disturbed in different ways. On the one hand, bone microremains have been described and quantified in SR7, reinforcing the highly fragmentary character of this site’s archaeological record. Furthermore, the identification of Fe-Mn nodules indicates temporary hydromorphic conditions that would have affected the integrity of bone remains. On the other hand, foreign mollusk remains were recovered from LEF, indicating an environment disturbed by anthropic activities. Finally, in LDM, high biological activity is reflected by frequent infilled channels and passage features. The identification of mineral components and pedofeatures through micromorphology contributes to the understanding of formation processes acting in shallow sites such as those analyzed.

La micromorfología de suelos es una técnica de aplicación en Arqueología que estudia muestras no disturbadas y permite visualizar los elementos constitutivos de un suelo y comprender la evolución pedológica del material originario mediante la observación de su composición, organización y pedorrasgos –características que se imprimen en los horizontes como consecuencia de procesos pedogénicos específicos–. Presentamos los resultados del análisis micromorfológico realizado sobre muestras de suelo tomadas en tres sitios arqueológicos de la Depresión del río Salado: San Ramón 7 (SR7), en un ambiente de humedal, Laguna Esquivel Fagoada (LEF) y Laguna del Medio (LDM), en las proximidades de dichos cuerpos de agua. Nuestro objetivo es identificar procesos de formación que puedan haber afectado la preservación del material arqueológico enterrado. Los resultados indican que los suelos en cada sitio son diferentes y han sido perturbados de diferentes maneras. Por una parte, en SR7 se describieron y cuantificaron microrrestos óseos, lo que refuerza el carácter fragmentario del registro arqueofaunístico de este sitio. Además, la identificación de nódulos de Fe-Mn indica condiciones temporarias de hidromorfismo que habrían repercutido sobre la integridad de los restos óseos. Por otro lado, en LEF se recuperaron restos de moluscos foráneos que indican un ambiente perturbado por actividades antrópicas. Finalmente, en LDM se observa una alta actividad biológica reflejada por frecuentes canales con relleno y estructuras de pasaje. La identificación de componentes minerales y pedorrasgos mediante la micromorfología contribuye a la comprensión de los procesos de formación que actúan en sitios someros como los analizados. application/pdf text/html https://revistascientificas.filo.uba.ar/index.php/Arqueologia/article/view/9984 10.34096/arqueologia.t28.n2.9984 spa Instituto de Arqueología, Facultad de Filosofía y Letras, Universidad de Buenos Aires https://revistascientificas.filo.uba.ar/index.php/Arqueologia/article/view/9984/10139 https://revistascientificas.filo.uba.ar/index.php/Arqueologia/article/view/9984/12059 Derechos de autor 2022 Alejandro Fernandez, Héctor Morrás, Emiliano Bressan Arqueología; Vol. 28 No. 2 (2022): May-August; 9984 Arqueología; Vol. 28 Núm. 2 (2022): mayo-agosto; 9984 1853-8126 0327-5159 Shallow sites Wetland Shallow lakes Hydromorphism Bioturbation Sitios someros Humedal Lagunas Hidromorfismo Bioturbación Site formation processes in archaeological sites from the Salado River Depression (Buenos Aires province, Argentina): a soil micromorphology analysis Procesos de formación en sitios arqueológicos de la Depresión del Río Salado (provincia de Buenos Aires, Argentina): análisis desde la micromorfología de suelos info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=arqueo&d=9984_oai
