"" Of course, we need more detailed researches and analysis, in order to estimate the real reason of thermal effects on the studied limestone. Whether it were human or natural factors, but the fact remains as the fact - recrystallization of biogenic siliceous limestone into a microcrystalline siliceous limestone. The result of this process we can see in the material, forming the wall polygonal blocks of the Saqsqywaman fortress. In normal nature conditions - this process is absolutely impossible.
Recrystallization process needs long-term temperature exposure up to of 1000 °C, followed by mixing the hydraulic quicklime analog with water, after what the slaked “lime paste” is formed. According to all the facts, mentioned above, this “mysterious clayish paste", forming the polygonal blocks of the ancient megalithic walls of the Saqsaywaman fortress, and the technology of its construction doesn’t leave any more doubts. The procedure of processing the raw “lime paste” (hydraulic lime) with its consequent mounting into the large blocks – doesn’t sound impossible anymore, even for the ancient peoples. So, the need in using of any fantastic high-tech equipment is completely eliminated, as well as the impossibly hard handwork on cutting and dragging the megalithic blocks to the place of construction.""
