Even within the known history of the area, the only humans to inhabit the region were nomads whose lifestyle would not leave any such structures behind.
The state-run news agency Xinhua in China reported on the pyramid, the pipes, and the research began by a team scientists sent to investigate in 2002.
The surrounding landscape is strewn with what Xinhua described as “strangely shaped stones.” Rocks protrude from the ground like broken pillars.
The head of the publicity department at the local Delingha government told Xinhua the pipes were analyzed at a local smeltery and 8 percent of the material could not be identified.
The rest was made up of ferric oxide, silicon dioxide, and calcium oxide.
