Sobre la edad de los hipogeos de Tierradentro, Colombia: intento de datación directa de la pintura roja mediante la magnetización remanente pictórica

A groundbreaking study on the UNESCO-listed National Archeological Park of Tierradentro, Colombia, has successfully dated the red paintings within its hypogeal tombs to between 1070 and 1150 AD using pictorial remanent magnetization analysis. This method, leveraging hematite grains' magnetic properties, revealed that the responsible minerals exhibit both ferromagnetic and antiferromagnetic characteristics. The findings align with a similar burial discovered at Rancho Grande in the La Cumbre-Pavas region, providing a significant contribution to resolving long-standing debates about the age of these culturally significant structures.
