Geological structure of the slab was determined: it cosists of three levels. The base is 14 cm chick, made of the firmest dolomite. The second level is probably the most interesting, “made” of diopside glas. The technology of its treatement is not known to modern science. Actually, the picture is marked on this level. While the third level is 2 mm thick and made of calcium porcelain protecting the map from external impact.

“It should be noticed, - the professor said, - that the relief has not been manually made by an ancient stonecutter. It is simply impossible. It is obvious that the stone was machined.” X-ray photographs confirmed that the slab was of artificial origin and has been made with some precision tools.
