Magnetometer Survey at the Newly‐discovered Roman City of Auritz/Burguete (Navarre). Results and Preliminary Archaeological Interpretation

Archaeological Prospection (2016)

Abstract This paper summarizes the principal geophysical results obtained at a recently discovered Roman city at Navarre. Prior to the survey, the extent of the affected areas and the characteristics of the settlement were unknown. The authors describe the field strategy applied and focus their discussion on the archaeological interpretation of the fluxgate gradiometer data. The results allowed for a detailed description of the layout in the main area revealing a city organized along the Roman road, which would have preceded the buildings. On the contrary, the results show important differences in magnetic contrast in the surveyed areas. Whilst the walls of the main area are well resolved, other areas do not show a discernible magnetic contrast even though their existence has been proven by other sources. The origin of these differences is discussed and preliminarily attributed to waterlogging or to differences in the thickness of the archaeological deposits. The magnetic survey, therefore, has shown itself to be a suitable technique for obtaining a preliminary assessment of the archaeological characteristics of the settlement, but cannot be used to definitively assess the affected areas. The results allowed zoning based on the contrast differences that will be used to guide further investigations. Copyright © 2016 John Wiley & Sons, Ltd.

Sistema kárstico multi-nivel Alkerdi-Zelaieta (Urdazubi/Urdax, Navarra): bajada del nivel freático frente a la (re)sedimentación

Martín Arriolabengoa Arturo Hermoso de Mendoza Victor Francisco Abendaño Trujillo Irantzu Alonso Álvarez Arantza Aranburu Artano

espanolEl sistema karstico de Alkerdi-Zelaieta tiene un desarrollo de mas de 5878m. En el se engloban distintas cuevas que estan geneticamente unidas, pero sepa-radas por la colmatacion de las galerias por sedimentos o colapsos. En todo caso,la organizacion de las galerias formadas en condiciones freaticas indica unaminima disposicion de 6 niveles de cuevas, que se han formado en un contextogeneral de bajada del nivel freatico. La formacion de cada nivel de cueva esta rela-cionada con procesos parageneticos, que se deben a un incremento de la cargasedimentaria respecto al caudal hidrico. La variacion en el aporte sedimentario serelaciona con cambios climaticos, de forma que cada vez que se repiten las con-diciones climaticas propicias se produciria el aumento en la disponibilidadsedimentaria, y con ello, el desarrollo de niveles de cueva en el sistema karstico.El area fuente de los sedimentos se localiza fundamentalmente en materialespaleozoicos y triasicos del entorno. En este sentido, una vez un nivel de cuevapasa a estar en condiciones vadosas, el sedimento depositado en ella comienzaa erosionarse y redepositarse en el nivel inferior que se esta formando, reciclan-dose una y otra vez hasta salir del sistema. EnglishThe Alkerdi-Zelaieta cave system is longer than 5878 m long. It iscomposed by genetically connected caves, which are currently separatedby sedimentary filling or collapses. Nevertheless, the disposition of thedifferent subhorizontal passages formed under phreatic conditionsshows at least 6 cave-levels, which have been developed in a wides-pread base-level falling context. The speleogenesis of each cave-levelis due to paragenesis, given by an increment on sediment input regarding the stream flow. Changes in sediment input rates are due to climatic changes, Therefore each time that those climatic conditions werereproduced, cave-levels would have been formed. The origin of the sediments are from Paleozoic and Triassic formations of the area. As such,using the meandering conduits that connect different cave-levels, sediments that filled the abandoned galleries were removed and depositedin a lower cave-level that was forming at the moment, being recycled repetitively until they leave of the cave-system.

Geoarchaeological Core Prospection as a Tool to Validate Archaeological Interpretation Based on Geophysical Data at the Roman Settlement of Auritz/Burguete and Aurizberri/Espinal (Navarre)

Geosciences (2017)

Ekhine Garcia‐Garcia James Andrews Eneko Iriarte Roger Sala Arantza Aranburu

Geophysical survey methods are broadly used to delimit and characterize archaeological sites, but the archaeological interpretation of geophysical data remains one of the challenges. Indeed, many scenarios can generate a similar geophysical response, and often interpretations can not be validated without access to the subsoil. In large geophysical surveys many anomalies are detected and validation through archaeological trenches can not be afforded. This paper analyses the validity of geoarchaeological core survey to check the archaeological interpretations based on geophysical results. The Roman site located at Auritz/Burguete and Aurizberri/Espinal (Navarre), provides a great case of study as many investigations have been carried out. After the gradiometer survey performed in 2013 a sediment core survey was designed. 132 cores were drilled using a hand-held coring machine and the sediments were analysed in situ. Site delimitation and archaeological interpretations based on magnetic data could be improved or corrected. In this regard, the core survey proved to be an useful methodology as many anomalies could be checked within reasonable time and resources. However, further geophysical investigations trough GPR revealed unexpected remains in areas where no archaeological deposits were identified through coring. Excavations showed poor conservation level in some of those areas, leading to thin archaeological deposits hard to identify at the cores. The sediment core survey, therefore, was proved to be inconclusive to delimit the archaeological site.
