The aim of this paper is to present the studies of the conditions of pictorial
elements in a rock art mural, to show the materials that were used and their
interactions with the open air. This academic exercise introduces new aspects in
the research process concerning the materials present in these rock art works
and leads up to the works about technology of pigments in the studied area,
extending the descriptive possibilities of the conservation conditions of rock art.
The study of the materials opens a route towards the conservation work, and
constitutes an essential way for the projected studies on dating. In this work,
pigments were analyzed, some accretions, the rock substrate and the possible
raw material of the rock art paintings. This analysis was done using Spectrometry
Infrared.
This investigation process is set in the context that the research group GIPRI has
developed, as an extension of the methodological model of record and
documentation of rock art in Colombia, especially in the cundiboyacense
highplateau. The rock chosen was “La Piedra de la Cuadrícula“, located in a set
of 167 rocks in Tequendama’s area, Soacha’s Municipality, in Cundinamarca’s
department. This sector is one of the most important archaeological sites of the
country. In this site cultural stratigraphic sequences between 12 500 B.P. and
2500 B.P. have been found. On the other hand, there have been developed very
important studies of the Pleistocenic and Holocenic environment.
