Visibile a: nessunoAbstractThe radiocarbon dating of inorganic materials such as lime mortars proved to be an innovative for the dating of the architectures, that allows to confirm data from the evaluation of the criteria, based moncler outlet serravalle on the archaeological stratigraphy. The tested method provides a an support where the dating obtained by the traditional method presents considerable limits. protocol developed in this study is based on the CryoSoniC method, a physical mechanical of moncler uomo the binder, focused on the separation of the binder from the aggregates and its from the potential contaminants that could affect the dating. The binder separation preceding the mortar dating, is followed to numerous analysis for the characterization the control of the samples in order to test the quality of the isolation of the binder piumini moncler scontatissimi and the of contaminants. procedure has been tested on 16 samples from archaeological site of Torba (province of Varese, which presents many construction phases between the Roman age and the early Middle therefore are represented various production techniques. characterization of the samples prove the success of the binder purification protocol by for the separation of the binder fraction from the sand fraction (aggregate), that to obtain reliable radiocarbon dates when the process of carbonation is prevalent on the reaction (that produces hydrate phases (C S H) and anionic clays). samples dated piumini moncler saldi through the accelerator mass spectrometry have been choosen based on three the moncler outlet online shop ratio between the carbonate fraction and the silicate fractions of the moncler saldi outlet sample, the carbon isotopes ratio 13C, the intensity of the luminescence observed piumini moncler outlet under microscope. In cases where at least two parameters of three are satisfied, the results of the dating are in agree the archaeological datas (Brogiolo et al. 2013), otherwise, the results from the binder taken from the mortar, the lime lumps and the samples made up of a high amount of piumini moncler moncleroutlet-i uomo clay are if compared the expected date. results show, on one hand, the successful of the separation and purification of the binder from the sand fraction (both carbonate and silicate) of the mortars, on the other hand the possibility to predict the reliability of the moncler saldi uomo results through the mineralogical and isotopic of the sedimented fractionArea 04 Scienze della terra > GEO/05 Geologia applicata
