(overexposure method of the Great Pyramid of Giza)
The author provides a general outline of the geological structure of the Giza Plateau. He points out that the pyramids occur within limestone quarries, about 50 – 70 meters above the current water level in the Nile River. The limestone strata dips towards southeast and are cut with fissures and the faults. There are numerous karst forms on the Giza Plateau. Beneath the Giza pyramids is a vast karst system, with cave corridors developed at several depths. During the preparation of the site for the construction of the Giza pyramids, surface and near surface karst forms were cut (removed). Accurate geological observations show that the pyramids were not built on flat and even surfaces. The pyramids have natural limestone plinths (”cores”). These “cores” were formed in the form of terrace steps. Limestone blocks were laid around such “cores” and a pyramid was formed. This suggests that, the construction of the Great Pyramid of Giza did not require approximately 2,500,000 limestone blocks (as is traditionally believed), and perhaps only 1/3 of this number. It should be noted here that the size of the limestone blocks decreases from the bottom of the pyramid towards the top.
There is an open question: how high do the natural rocks reach under the Great Pyramid? The observations so far show that the natural limestone “core” can be up to the height of the so-called Queen’s Chamber. Or maybe it goes higher, to the basis of the so-called The King’s Chamber? Such a limestone “core” of the pyramid would undoubtedly facilitate the supply of large granite blocks for the construction of this structure and prevent the entire structure of the pyramid from “falling apart” under the pressure of the aforementioned granite blocks and the limestone blocks of the structure of the pyramid.
Another important question is: are there any other chambers, corridors, etc. in addition to the known voids inside the Great Pyramid? To answer this question, the author proposes to use the GPR method to x-ray the Great Pyramid of Giza using low-frequency electromagnetic waves (EM waves). Such a project was published in 2008 at a conference in Birmingham and was presented to the Supreme Council of Antiquities in Cairo, too. The assumption of the project is to perform linear GPR profiling, at 1 m. intervals, on each outer surface of the pyramid’s “walls”. An antenna with a central frequency of 15 MHz will be used for the tests, allowing to obtain an echo of EM waves from a distance of 240 m and a 50 MHz antenna, allowing to search for empty spaces up to a depth of about 50 m from the surface of the pyramid walls. The collected data will be processed in the 3D system and in the 2D system.
During the presentation, examples of the analysis of GPR data from the Giza plateau will be shown and the results of GPR research on the example of the pyramid model from Mexico will be shown.
