Una de cal por las que van de arena: un estudio diacrónico de los estucos de Calakmul y Palenque

this paper presents the results of petrographic and x-ray fluorescence analyses carried out in lime plaster samples from calakmul and palenque. technological differences observed in the samples are though to represent different building traditions and these changes are discussed in terms of the environmental contexts, the availability of raw materials, and the socio-political contexts of each of the chronological periods. a clear tendency of replacing lime for clays in order to produce mud plasters was clearly documented in terminal classic materials. we think this is a consequence of the breakdown in building traditions caused by the collapse of the sociopolitical structure of the sites, exacerbated perhaps by shortages of firewood. the selection of raw materials and the problems in the chronology of palenque's buildings is also discussed.
