It should be pointed out that Hawass is pumping vast quantities of water from under the Sphinx since about 2013. This is from an elevation only a little higher than the bottom of the Osiris Shaft and only 400' away. This is causing an inflow of ground water and sea water apparently. But there should still be some carbonation in this water.

The bizarre red, white, and yellow mineral encrustations here are puzzling, and I cannot explain them. I looked at them as closely as I could, and the more closely I looked the more puzzled I became. They seem to be bubbling up from something, with layers of encrustation being successively deposited on top of earlier layers. Perhaps the ‘efflux of Osiris’ is leaking upwards!

I believe it is almost certainly CO2 causing this bubbling. Certainly carbonated aquifers are not in the least unusual.
