El dolmen de Soto es uno de los mayores monumentos megalíticos de Europa. Fue publicado por H. Obermaier en 1924 y casi cien años después, este volumen presenta la primera documentación gráfica sobre sus soportes, incluyendo análisis de pigmentos y dataciones del contexto arqueológico interno y externo del sepulcro. Su arquitectura es el resultado...

Full-text available
Vestiges of prehistoric paintings in the Dolmen of Soto (Trigueros, Huelva, Spain) have been studied by Raman microscopy and SEM/EDX techniques. The pigment used have been identified. The presence of amorphous carbon have been used to date these decorations using plasma oxidation technique to achieve radiocarbon data.

The documentation of paint accompanying the engraved decorations in dolmens in the Iberian Peninsula has en-abled the development of a tested methodology. Its appli-cation to engraved dolmens in Brittany and to materials and architecture in the Orkney Islands has determined the range and variability in the depictions at megalithic sites in Atlantic...
Conference Paper
Three different sequences, named TsA, TsB and TsC, exist in the telomeres of the insect Chironomus riparius. Transcriptional basal activity has been observed in telomeres with TsA and TsB sequences, being the transcription highly hyperactivated upon heat shock in TsA telomeres. On the other hand, neither basal nor stressed activated transcriptions...
Article
Rock paintings of two recent discovered rock shelters, Galb Budarga and Tuama Budarga, from the southeastern area of theWestern Sahara, Sahrawi Arab Democratic Republic, have been studied by micro-Raman spectroscopy and scanning electron microscopy coupled with energy dispersive X-ray spectrometry in order to characterize the composition of the mat...

The Atapuerca archaeological complex in Spain, a UNESCO World Heritage Site, is considered to be one of the 20th century's most important scientific discoveries. Micro-spectroscopic studies of rock art paintings from the Cueva Mayor of this complex have been carried out in order to characterise the composition of the pictorial materials, substrates...

A series of rock art pictographs in the form of hand stencils discovered in two sites of the Yabrai Mountain, Inner Mongolia Autonomous Region (China) has been studied by micro-Raman spectroscopy, X-ray photoelectron spectroscopy and scanning electronic microscopy combined with energy dispersive X-ray spectroscopy for the first time. These studies...

Full-text available
Remains of pictorial decorations in a series of six representativemegalithicmonuments of Brittany (France) and two French stelae have been studied by micro-Raman spectroscopy for the first time. Fungal colonies on the painted orthostats made it difficult to obtain in situ Raman spectra of the paint components. Nevertheless, paint micro-specimens st...
Chapter
The decoration of megalithic monuments is one of the ritual actions that define the spaces that were dedicated to the ancestors. Consideration of the artistic programmes employed during the construction of megalithic tombs provides parameters for analysis that support the search for the ideology and symbolic meaning of these monuments. Most of the...
Article
Full-text available
Megalithic art is a well-known feature of the Neolithic chambered tombs of Atlantic Europe. The surviving evidence consists largely of carved motifs, and, until recently, painted megalithic art was thought to be restricted to western Iberia. Recent discoveries have expanded that distribution, assisted by new methods of detection, recording and anal...
Article
The composition of the materials present in prehistoric paintings discovered on the walls of the Abrigo Remacha rock shelter (Villaseca, Segovia, Spain) has been characterised by micro‐Raman spectroscopy. In addition, scanning electron microscopy and energy dispersive X‐ray microanalysis have been used as auxiliary techniques. The results show that...
Article
Full-text available
The use of technique is usually considered in European megalithic art as an indicator of the level of culture sophistication attained by a particular community. Traditionally, it was considered that only the Iberian Peninsula is home to painted dolmens. The analysis of chamber H of the Barnenez tumulus together with some information scattered over...
