The archaeological investigations carried out in the Valley of Colima in recent years have, as one of its main limitations, the lack of a chronological sequence, based on absolute dating. Based on a review of the chronology proposed by Isabel Kelly, the present work describes the efforts focused on beginning the construction of the sequence, through the archaeological-magnetic study of materials from primary contexts excavated in three sites, whose shared characteristic is the presence of circular plazas. The study of ceramic sherds and burnt bajareque fragments has allowed to obtain the first absolute dates for this type of sites, placing them within what is known as the Mesoamerican Classic period.
