Mineralogical and Spectroscopic Characterization of Some Products Resulting from the Weathering Process on the Tomb of Nakht-Djehuty (TT189), Western Thebes, Upper Egypt

A study of the tomb of Nakht-Djehuty (TT189) in Western Thebes, Egypt, reveals that salt weathering—driven by the region's geological and environmental conditions—has led to significant damage, including flakes, salt efflorescence, biofilms, and hard crusts. The primary salts identified are sodium chloride (halite, NaCl) and sulfates (gypsum, bassanite, and anhydrite). Fourier transform infrared spectroscopy detected calcium oxalate, likely from the biodegradation of organic binders or coatings used in ancient restorations. This research sheds light on the complex chemical processes affecting Egypt's heritage sites, with implications for their preservation.
