Dating analysis of potsherds from three of the six units recently excavated in the Tingambato archaeological site, central-western Mexico, was carried out employing two regional intensity Paleosecular Variation Curves (PSVC) and the global model SHA.DIF.14k. A complete evaluation of the ceramic fragments' magnetic characteristics was done to determine the samples' magnetic carriers and their capacity to provide reliable archaeointensity data. The presence of two magnetization components in five analyzed potsherds provides two snapshots of the Earth's magnetic field intensity behavior at different temporalities. Intensity values were obtained following strict quality criteria, including cooling rate and anisotropy corrections. The principal causes of failure in archaeointensity experiments are associated with the alteration of the magnetic mineralogy during the heating of the specimens and with the presence of multidomain grains. Intensities within the established quality criteria were obtained for four out of the eleven ceramic fragments analyzed. The dating exercise shows a better correspondence of the intensity values with the regional curves than with the global model, especially for the temporal range between AD 400–1200, for which both regional curves are in good agreement. The obtained archaeomagnetic ages had a good correspondence with the radiocarbon ages reported in previous studies. By determining two archaeointensity values in one of the studied potsherds: one associated whit its fabrication and the other related to the fire (after which the site is supposed to be abandoned), archaeomagnetic ages of the probable end of Tingambato occupation were estimated.

使用两个区域强度古城变化曲线（PSVC）和整体模型SHA.DIF.14k，对最近在墨西哥中西部Tingambato考古现场发掘的六个单位中的三个进行了定型分析。对陶瓷碎片的磁性特征进行了完整的评估，以确定样品的磁性载体及其提供可靠的古强度数据的能力。在五个被分析的陶器中存在两个磁化分量，提供了在不同时间的地球磁场强度行为的两个快照。强度值是根据严格的质量标准（包括冷却速率和各向异性校正）​​获得的。古代强度实验失败的主要原因与样品加热过程中磁性矿物学的变化以及多畴晶粒的存在有关。对于所分析的11个陶瓷碎片中的4个，获得了已建立的质量标准内的强度。测年表明强度值与区域曲线的对应关系比全局模型更好，尤其是在AD 400-1200之间的时间范围内，这两个区域的曲线都吻合良好。获得的古地磁年龄与先前研究中报道的放射性碳年龄有很好的对应关系。通过确定所研究的陶器之一中的两个古强度值：
