| Abstract: | The present work completed the research that we have developed during the last years in the cave. The analysis of the painting matter has been made to recognize the anthropic origin of certain figures, to compare the natural iron oxide deposits with one of the paintings with the purpose of establishing the supply area, and to compare the pictorial matter of the different figures to characterize the technical process of the cave. Nineteen samples were taken, from the painted figures and from natural depots. The analysis made in the C2RMF have confirmed the anthropic origin of two figures and have shown the preparation of different pigments for a same painting. |
