Abstract
The series of underground tombs from Tierradentro, Colombia, carved in the soft volcanic rock, contains multiple artistic manifestations made of red paint. Despite their enormous archaeological and heritage importance, there is still a strong controversy about the age of these hypogea. The pictorial remanent magnetization, mostly carried by hematite grains, was analyzed for the Alto de Segovia hypogea. Hysteresis cycle experiments and continuous thermomagnetic curves indicate that both ferromagnetic and antiferromagnetic minerals are responsible for the magnetization. Alternating field demagnetization revealed the mean magnetic declination only for the Segovia 30 hypogeum, yielding an AD 1070–1150 time interval for the elaboration of the painting. This dating is contemporary to a similar burial found at the Rancho Grande site, in the La Cumbre-Pavas region.
