El arqueomagnetismo es una técnica de datación que permite datar el último calentamiento de ciertos materiales arqueológicos y geológicos quemados. El estudio de la termorremanencia registrada en materiales como hornos, hogares o rocas volcánicas, permite reconstruir las variaciones en la dirección y/o intensidad del campo magnético terrestre a lo...

Fumier sequences play a primary role in the study of livestock management and the use of space in prehistoric pastoralist societies. These sequences are formed when dung accumulated in sheepfold caves and rock shelters is burnt, resulting in an overlapping of burnt and unburnt sedimentary layers. Thus, fire is a key taphonomic agent in the formatio...

The analysis of the magnetic record of burnt archeological materials provides valuable information of both chronological and geophysical interest. Archeomagnetic studies carried out on independently well-dated materials allow to obtain data in order to improve and temporally extend the reference curves of the variations of the Earth’s magnetic fiel...

Here we present preliminary results for new methodological approaches to integrating archaeomagnetic methodologies with archaeological soil micromorphology.

By studying combustion structures, which conceal information about anthropogenic activity, we might learn about their makers. This is especially important for remote time periods like the Middle Paleolithic, whose archaeological record comprises numerous combustion structures. The majority of these are simple, flat, open hearths, although a small n...

The site of Gruta da Aroeira (Torres Novas, Portugal), with evidence of human occupancy dating to ca. 400 ka (Marine Isotope Stage 11), is one of the very few Middle Pleistocene localities to have provided a fossil hominin cranium associated with Acheulean bifaces in a cave context. The multianalytic study reported here of the by-products of burnin...

The progressive southward reoccupation of territories of the Iberian Peninsula by the Christian kingdom against the Muslims from the eighth century AD onwards is a well-known process. However, there are few well-dated sites of this period, especially in the northern plateau of Spain. Here we report the full vector archaeomagnetic dating of two hear...

There is a relatively low amount of Middle Paleolithic sites in Europe dating to MIS 4. Of the few that exist, several of them lack evidence for anthropogenic fire, raising the question of how this period of global cooling may have affected the Neanderthal population. The Iberian Peninsula is a key area to explore this issue, as it has been conside...

The radiocarbon technique is widely used to date Late Pleistocene and Holocene lava flows. The significant difference with palaeomagnetic methods is that the 14C dating is performed on the organic matter carbonized by the rock formation or the paleosols found within or below the lava flow. On the contrary, the archaeomagnetic dating allows to date...

During the course of the excavations of the San Quirce open-air archaeological site in Spain, an unusual negative structure was identified in the Holocene level dated ca. sixth millennium cal BC. A fire pit alongside a single post-hole and intense fire-burning activity was recorded. Yet, the most striking feature of the structure is the absence of...

Archaeomagnetic and rock-magnetic methods are of great value in the identification of archaeological fire, especially in Palaeolithic sites where evidence is usually scarce, ambiguous or poorly preserved.

Archeomagnetism is an example of the interdisciplinary nature of most archeometric research: It requires expertise from both earth sciences and archeology, and the results are of benefit for both disciplines (Aitken, 1964). The geophysicist can gain information about the magnetization of materials and the behavior of the geomagnetic field, while th...

Geomagnetic reversals are global phenomena, for about 50 years the paleomagnetists attempted to acquire as many detailed records as possible using the magnetic memory of sediments and lava flows. Yet, transitional field behavior remains poorly characterized largely because of sporadic aspect of volcanic eruptions. In some specific cases, paleosols...
