Concentrations of light elements using micro-PIXE and micro-PIGE reveal the elemental composition of the various materials used for the construction of the pyramids. Light elements (mainly Na, Cl and S) show a very heterogeneous distribution for the pyramid’s material in contrast with the extremely homogeneous distribution of these elements in natural limestone from quarries of Turah and Maadi and the bedrock of Saqqarah. The micro-PIXE elemental maps present new evidence for the application of a molding procedure.
