Dzibanché Stuccos: Arqueomagnetism Dating and Manufature Tecniques.


The archeological site of Dzibanché, Quintana Roo, has polychromed stucco remains that seems to date to the Middle Classic when the Kaan dinasty ruled at Dzibanché. The aim of this investigation was to determine the composition of the stucco and the painting (petrography, SEM-EDS, XRD) and date them.The antiferromagnetic hematite in paintings contains remanent magnetization (PiRM). Magnetic record could date them if changes in direction and intensity of the geomagnetic field have been well characterized. The employed curve for dating is improved from Wolfman (1 to 1200 dC ) with new archaeomagnetic data supported by radiocarbon dates.

Stucco contains manly calcite, dolomite, chert, clays, soil and some organic features; the pictorial layer have at least 2 layers of red pigments mostly constituted by hematite. Four murals were sampled, 8 to 10 oriented specimens were taken with double-sided tape. The samples were demagnetized by alternating fields (10 to 40 mT) in order to get their characteristic magnetization. The mean directions were obtained employing Fisher statistics and dating was performed with Bayesian statistics (RENDATE).Obtained dates: 626-647 dC, Structure 2; Pequeña Acrópolis palaces 394-429 dC & 500-529 dC, southern, 417-528 dC eastern , 445-497 dC northern palace.
