Photons and electrons for the study of a white veil covering some walls in prehistoric caves

A white concretion, partially covering walls in prehistoric caves within the UNESCO-listed Vézère Valley, has been structurally and chemically characterized using advanced techniques. The study identified two primary calcium carbonate facies: moonmilk and coralloids. This research marks a significant step toward understanding the formation of unexpected layers on cave walls, which could provide insights into the environmental conditions and chronology of these sites. Future work aims to explore the climatic factors influencing these formations over long periods.
