150,000-Year-Old Pipes in China

150,000-Year-Old Pipes Baffle Scientists in China: Out of Place in Time?


By Tara MacIsaac Epoch Times

Oopart (out of place artifact) is a term applied to dozens of prehistoric objects found in various places around the world that seem to show a level of technological advancement incongruous with the times in which they were made. Ooparts often frustrate conventional scientists, delight adventurous investigators open to alternative theories, and spark debate.

In a mysterious pyramid in China’s Qinghai Province near Mount Baigong are three caves filled with pipes leading to a nearby salt-water lake. There are also pipes under the lake bed and on the shore. The iron pipes range in size, with some smaller than a toothpick. The strangest part is that they may be about 150,000 years old.

Dating done by the Beijing Institute of Geology determined these iron pipes were smelted about 150,000 years ago, if they were indeed made by humans, according to Brian Dunning of 

And if they were made by humans, history as it is commonly viewed would have to be re-evaluated.

The dating was done using thermoluminescence, a technique that determines how long ago crystalline mineral was exposed to sunlight or heated. Humans are only thought to have inhabited the region for the past 30,000 years. 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. 

Though some have since tried to explain the pipes as a natural phenomenon, Yang Ji, a research fellow at the Chinese Academy of Social Sciences, told Xinhua the pyramid may have been built by intelligent beings. He did not dismiss the theory that ancient extraterrestrials may be responsible, saying this theory is “understandable and worth looking into … but scientific means must be employed to prove whether or not it is true.”

Another theory is that it was built by prehistoric humans with techniques lost to humans of a later period. 

The pipes lead into a salty lake, though a twin lake nearby contains freshwater. 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. The silicon dioxide and calcium oxide are products of long interaction between the iron and surrounding sandstone, showing the ancient age of the pipes. Liu Shaolin, the engineer who did the analysis, told Xinhua: “This result has made the site even more mysterious.”

“Nature is harsh here,” he said. “There are no residents let alone modern industry in the area, only a few migrant herdsmen to the north of the mountain.”

To further add to the mystery, Zheng Jiandong, a geology research fellow from the China Earthquake Administration told state-run newspaper People’s Daily in 2007 that some of the pipes were found to be highly radioactive.  

Other Theories

Jiandong said iron-rich magma may have risen from deep in the Earth, bringing the iron into fissures where it would solidify into tubes. Though he admitted, “There is indeed something mysterious about these pipes.” He cited the radioactivity as an example of the strange qualities of the pipes.

Others have said iron sediments may have washed into the fissures, carried with water during floods.

Though Xinhua and other publications in China have referred to a pyramid or even a mysterious pyramid in which the pipes were found, some have said it was a pyramid-shaped natural formation. 

Another theory is that the pipes are fossilized tree roots.  Xinmin Weekly reported in 2003  that scientists found plant matter in an analysis of the pipes, and they also found what looked like tree rings. The article related the finding to a geological theory that in certain temperatures and under certain chemical conditions, tree roots can undergo diagenesis (transformation of soil into rock) and other processes that can produce iron formations.

Reports on the tree-root explanation for the so-called Baigong pipes often lead back to this Xinmin Weekly article or lack citation. It’s unclear exactly how well-supported this theory is in relation to the Baigong pipes.

An article published  in the Journal of Sedimentary Research in 1993 describes fossilized tree roots in South Louisiana in the United States.

homo capensis is a load of crap. there has never been a homo capensis in science. in 1913 they found the boskop man which was a skull that was human but with some defects. many claimed it was a new species but there is no evidence to confirm or back the claim.also larger brains do not mean higher intelligence. for example dolphins have larger brains than we do. now while they may be intelligent they dont use tools and form societies and civilization or do science or anything near our mental capabilities. so brain size doesnt necessarily prove intelligence. a much better prediction of intelligent is brain to body size ratios but even that isnt perfect.

How about the Homo Capensis ? How long have they been around ? From what I have read about those critters, if in fact they do or did exist, there are literally hundreds of their skulls surviving. I would assume other bones survived also. The skulls are unlike our human skulls in several ways. First, they have an elongated structure. The bony structure is thicker and heavier than human skulls. The cranial cavity is 25% to 33% larger than humans, indicating they may have had a larger brain and consequently more intelligent than humans. Instead of 3 parietal lobes that homo Sapiens have, the Homo Capensis has only 2 lobes. The eye sockets are larger and rounder and more shallow than human eye sockets, and at the rear of the skull there are a hole or two that some surmise nerves or blood vessels passed through, possibly to nourish the larger brain. DNA has been obtained and tested, and the preliminary results indicate that these critters are NOT human, and if they did mate with a human, the first generation offspring would be sterile. Now, here we are, into the 21st century, and we are just getting scientific evidence that Capensis exists. How many other critters exist in heaven, and on Earth, that we don't know about ? Scientists estimate that about 13.5 billion years have gone by since the Big Bang. How many other Big Bangs occurred prior, in the sea of time we call Eternity ? It is impossible to tell what artifacts of the past still exist, and what may be discovered. To dismiss out of hand any possibility without investigation is the height of ignorance and arrogance.

....and yet we should remember that many of the ruins of ancient sites we know of today appeared to be natural formations before someone discovered differently and cleaned them up.

A good example is Cholula Tlachihualtepetl in Mexico. It looks like a hill with a spanish cathedral on top. But that "hill" is a friggin' giant pyramid.

Actually, that is well within the range many scientist put us as being genetically human. Most say closer to 200,000 years. Still, when you look at these things it is obviously a natural formation even if it isn't obvious how it came to be.

I am fairly sure that Homo Neanderthal and his neighbors would object to being referred to as semi ape like creatures. Better check the time line of Epochs and Eras against Evolutionary timelines for Hominids.
