The newspaper reported that Panzhihua is known as the "Steel City." However, how long is the city's smelting history? A recent archaeological excavation referred this time to more than 2,000 years ago. When the Sichuan Provincial Institute of Cultural Relics and Archaeology conducted an archaeological excavation on the Chengdu-Kunming Railway (Miaopeng Section), it discovered the plutonium and suspected copper slag during the Shang and Zhou dynasties in front of the temple gate in Miyi County. The introduction of the site of the archeological site, Chen Yan, at least shows that people at the time already knew how to smelt.
The archeology was carried out in conjunction with the expansion and reconstruction of Chengkun Railway. In May 2013, when the Provincial Archaeological Institute and the local cultural relics department conducted an archaeological survey of the Mi-Chan section of the Chengdu-Kunming railway, the piece was found on the hillside terraces on the southeast of the 8th group of Shagou village on the east side of Binggu Town in Miyi County. Ruins. Chen Yun revealed that at the time the site was a terraced area that was remodeled by the common people. However, on the terraces and field terraces, the sandstone pieces of the Shang and Zhou period were scattered on the surface. Where did they come from? The archeologists drilled and discovered that the earthenware contains stoneware pottery during the Shang and Zhou dynasties and the Warring States period, initially confirming that it was a settlement site during the Shang and Zhou dynasties. Because the name of the local small place is called in front of the temple, it is named before the temple gate.
After four reviews, on January 4, 2015, the Provincial Archaeological Department carried out rescue excavations on the area where the construction of the railway will be destroyed. Surprises soon appeared.
In the excavated area of ​​nearly 500 square meters, archeologists discovered the accumulation of up to 9 layers of archaeological sites: about 40 ash pits, 3 houses, and 2 trenches have been found in ancient cultures. Dozens of column holes and two stoves. In addition, nearly 200 pottery bowls, pots and pans, stone axes, stone pots, and other utensils and work tools were found. According to these intensive archaeological remains, archaeologists discovered that the ruins in front of the temple are a rare settlement site in the Shang-Ming period in Panxi. Chen Hao believes that since some of the unearthed pottery pieces already have the characteristics of the late Neolithic remains of the Jinsha River basin, it is not ruled out that the upper limit of the age of the pre-temple ruins may be earlier.
However, the focus of the discovery of the most important discovery was the discovery of two suspect slags left by smelting. Chen Hao revealed that archeologists found a large amount of red-burned earth blocks and regular ash pits in the cultural layers of the Shang and Zhou dynasties, which are completely different from ordinary people's ash pits that used to cook and cook. What exactly did they do? As the excavation progressed, the archaeologists found two slags and rafts in the soil. They were all about four or five centimeters in diameter. The slag was tested with a magnet and there was no magnetic reaction. Chen Hao said that whether this piece of slag is copper or iron ore is still known to be discovered after professional inspection. However, regardless of the type of metal, it has been proven that the ancestors of the “iron and steel capital†have begun to use smelting as early as 2000 years ago, using rich mineral resources underground. Temple ruins. Slag unearthed in front of the temple gate. Stone axe unearthed in front of the temple gate.
