Guo Ziqi, a scientist who ordinarily searches for oil too minerals deep below ground, has been helping shed lite on an ancient reason buried along the Silk Road.

Invited past times archaeologists from Xinjiang's Institute of Cultural Relics too Archaeology, they used geophysical exploration technologies to brand a preliminary finding of the location, width too burial depth of the Qiuci urban nitty-gritty walls.
"When the archaeologists asked me to assist expect for the ancient relics past times using our technologies, I initially felt it was similar hitting mosquitoes alongside a cannon," Guo joked. "We ordinarily role our technologies to search for resources buried deep inwards the Earth, then it would endure much easier to expect for the relics, which are comparatively real to a greater extent than or less the surface too would display rigid signals."
"I'm real interested inwards searching for ancient relics. I desire to contribute to uncovering the mysteries of lost civilizations," he said. "But nosotros couldn't apply geophysical exploration technologies straight to archeology. We made some adaptation."
Qiuci State was 1 of 36 states inwards the Western Regions, a term used inwards the Han Dynasty (202 BC to 220 AD) for areas W of Yumen Pass, including present-day Xinjiang too parts of primal Asia.
Qiuci was on the ancient Silk Road too was a melting pot of Chinese, Indian, Islamic too European cultures.

However, it was lost to history alongside most all of the urban nitty-gritty walls destroyed past times floods too human activities too most of the remains covered past times modern buildings, pavements too drainage pipes, making it hard to detect.
Archaeologists convey searched for the ancient reason for iii years, mainly relying on historical records too a traditional Chinese tool called the Luoyang shovel to search for relics.
But the shovel cannot endure used on paved roads too stony places, where Guo too his squad displayed their skills to the full. They brought a ground-penetrating radar too a high-density resistivity meter.
"These 2 instruments complement too verify each other to confirm the beingness of hush-hush rammed earth, indicating remains of the urban nitty-gritty walls," Guo said.
The ground-penetrating radar has a high resolution too tin forcefulness out "see" objects at the centimeter scale, piece the high-density resistivity meter tin forcefulness out discovery layouts of long-buried river courses, tombs, walls too edifice foundations.
They institute the outer urban nitty-gritty wall of Qiuci was fifteen to xviii meters wide, alongside the widest business office reaching thirty meters. Some sections were buried 2.5 meters underground.
Scientists also institute the northeast corner too the southwest corner of the wall were arc-shaped instead of perpendicular.
"We also got the oil arrive at of the ancient palace, which needs archaeologists to excavate to confirm," Guo said.
The geophysical exploration has offered scientific prove for farther inquiry on Qiuci, too the technologies tin forcefulness out endure applied inwards futurity searches.
Guo said his squad would assist Islamic Republic of Iran inwards exploring an ancient urban nitty-gritty along the Silk Road inwards July.
"I believe our methods tin forcefulness out assist brand to a greater extent than discoveries inwards researching ancient civilizations of Mesopotamia too Egypt," said Guo. "Searching for lost civilizations has zero to create alongside my ain profession. But I believe natural scientific discipline tin forcefulness out assist solve problems inwards humanities studies."
