Copper Contamination Study Proves Late Pre-Dynastic Activity at Giza. 2024 paper by Martin Odler et al. titled 'The Construction of the Giza Pyramids Chronled by Human Copper Contamination' Geochemical analysis of sediment cores from Khufu harbor on Nile floodplain First significant rise in copper contamination: late pre-dynastic 3,265-3,185 BC
Younes G. et al. (2024) traced copper contamination in Khufu harbor sediments. Sediment core analysis from the Nile floodplain at Giza reveals human activity pulses. First significant rise in copper contamination correlates with late pre-dynastic period. Second spike aligns with First Dynasty activity, associated with tomb construction. Third spike corresponds to late Third Dynasty, followed by major contamination during Fourth Dynasty—specifically the regnal years of Kings Khufu, Khafre, and Menkaure, consistent with Great Pyramid construction phases. The study, titled 'The construction of the Giza pyramids chronicled by human copper contamination,' was published in 2024.
