In total of 143 archeological samples were obtained from the Xalla site and 40 samples from Teopancazco, both belonging to
Teotihuacan culture. Five contructive stages are recognized at Xalla. The samples consist mainly burned stuccos dated as 550
AD by C14 systematics and other unburned specimens (containing fine grained scoria) spending time interval between 100 AD
and 350 AD. Vectorial composition of natural remanent magnetization were investigated using stepwise alternating field
treatment. Mainly univectorial components were obtained for the majority of samples showing well clustered remanence
directions. The possible dates are retrieved using a new paleosecular variation reference curve (Hueda et. Al., 2004).
