Resumen:
The study carried out in different areas of the city of Mérida, Yucatán, has the objectives of locating pre-Hispanic or colonial archaeological remains, register leveled areas from the Mayan times and to verify the existence of karstic areas in the subsoil, among others. For these studies in urban areas, we used ground penetrating radar (GPR), one of the non-invasive geophysical techniques. This technique allows to detect remains below the modern street pavement without interference in urban areas, reducing the need of excavation or other actions that may modify the area to be studied. In the present stage of the project, we selected places where the exploratory lines performed in previous seasons suggested the possibility of having archaeological remains below the city streets. We chose two zones where the bibliographic research indicates the existence of large platforms that were part of the T’Ho Mayan city, in another zone we verify the existence of a sculpture monument, and we also studied an archaeological park in the outskirts of the city. Most results confirmed the hypothesis, so we found extensive horizontal reflections interpreted as ancient leveling in the places where the platforms could be. In the Kambul zone, we found a clear hyperbolic reflection interpreted as a buried, large stone. In Chen Hó archaeological park, we found some cultural features inside the mounds. Besides the cultural features, we found many deep anomalies, interpreted as karstic zones, which are relevant because in the future they might reach the surface. © (2024), (Boletin de la Sociedad Geologica Mexicana).
