Lanthanides Revealing Anthropogenic Impact within a Stratigraphic Sequence
2014
Difficulties to differentiate between anthropogenic and natural processes in the formation of archaeological deposits are crucial for a correct interpretation not only of the actions involved in the development of archaeological sites, but also of their occupation-abandonment dynamics and the understanding of their spatial behaviors and relationship with the environment. We have carried out lanthanides (rare earth elements “REE”) analysis to distinguish anthropogenic from natural stratigraphic units in sediments using the advantage of the high sensibility, precision, and accuracy of ICP-MS measurements. In the Neolithic site of Mas d’Is (Alacant, Spain), we have applied REE analysis in a hu…
Long-Term Socioecology and Contingent Landscapes
2004
Long-term social and natural processes reciprocally interact in spatially and temporally dynamic socioecosystems. We describe an integrated program of patch-based survey and subsurface testing aimed at studying long-term socioecology, focusing especially on the transition from foraging to farming in Mediterranean Spain. Measures of landuse ubiquity, intensity, dispersion, and persistence trace late-Pleistocene through mid-Holocene socioecological trajectories in four upland valleys. Although farming replaced foraging in all four valleys, the timing and nature of this transition varied because of cumulative interactions between social and natural processes. These processes continue to struct…
Una revolución científica a la que Educación Química quiere contribuir
2014
AbstractSustainability Science aims to integrate the study of social development and natural processes to fa a new paradigm thatvour both of them and make possible the transition to Sustainability. This deep scientific revolution cannot be the result of just a new knowledge discipline: it must become a new paradigm that impregnates the ensemble of scientific disciplines and social activities.ResumenLa Ciencia de la Sostenibilidad tiene como objetivo integrar el estudio del desarrollo social y los procesos naturales para favorecer a ambos y posibilitar la transición hacia la sostenibilidad. Esta profunda revolución científica no puede ser el resultado de solo una nueva disciplina del conocim…
Disentangling human from natural factors: Taphonomical value of microanatomical features on archaeological wood and charcoal assemblages
2020
International audience; Archaeobotanical charcoal and wood analyses rely on the observation of different macro and microanatomical features affecting wood structure to variable extents. These features may result from a wide range of intrinsic and extrinsic factors alluding to different stages of the wood's taphonomical history: initial growth conditions, human selection, transformation/use and discard, post-depositional processes and archaeological sampling strategies. Papers in this volume address taphonomy in this broad sense, through recent methodological work mainly based on experimentation and case studies from a variety of chrono-cultural and geographical contexts. The authors present…
