Chinanews.com, June 27th. On the 26th, the estuary Shenyin, the archaeological achievement exhibition of the Pengshan Jiangkou battlefield site in Meishan, Sichuan Province, officially opened at the National Museum of China. This exhibition is sponsored by the National Museum, Sichuan Provincial Department of Culture, and Meishan City Government. The exhibition is from June to September 2018, and the exhibition period is 3 months. A total of 500 cultural relics (groups) found in the ancient battlefield sites of Jiangkou, including the ancient Jiangkou ancient There were 479 hydrological relics excavated from the battlefield site, 13 recovered cultural relics from Pengshan Public Security, and 8 cultural relics from the Pengshan Cultural Management House.
The exhibition is divided into three parts: the preface, Shen Yinshui, and the new archeological chapter. The Preface Hall introduces the general situation of the Jiangkou site and the discovery of cultural relics before scientific archeological excavations. The Shenyin water section fully displays important cultural relics in water. It is divided into two units: Daxi Shenfu and Ming Dynasty society. It mainly displays the cultural relics related to Zhang Xianzhong's Daxi regime and the cultural relics of the estuary. There are also jewellery and daily appliances in the middle and late Ming Dynasty. The new chapter of archeology introduces new methods of archaeology of the inner water cofferdam, various new technologies used in excavation, and the important role of public archeology in this excavation through text, pictures, videos, immersion projection and other means.
Jiangkou Shenyin Site (Pengshan Jiangkou Ancient Battlefield Site) is located in the Minjiang River in Jiangkou Town, Pengshan District, Meishan City, Sichuan Province. It was announced in 2010 as a Meishan city-level cultural relics protection unit with a distribution area of 1 million square meters. Documents since the Ming and Qing Dynasty Zhongduo records that Zhang Xianzhong, the leader of the Western Army in the late Ming Dynasty, was once here.
In January 2017, with the approval of the State Bureau of Cultural Relics, the first archeological excavation of the Jiangkou Shenyin site carried out hundreds of gold coins, thousands of gold wares, and tens of thousands of silver wares. As of April 2018, the archaeological excavation of the second phase of the Jiangyin Shenyin site has been completed. The archaeological excavation of the Shenyin site in the mouth of the river has unearthed an area of more than 23,000 square meters, and more than 42,000 cultural relics of various types have been excavated. It was named one of the top ten new archeological discoveries in 2017 in China. This major discovery not only confirmed the historical mystery of Zhang Xianzhong's "Yangkou Shenyin" in the late Ming Dynasty, but also the most direct display of political, military, and social life in the middle and late Ming Dynasty.
This archeological work aims to confirm the nature of the site, understand the scope of the site and the distribution of cultural relics, find war relics, especially relics related to shipwrecks, and discover more types of relics, and carry out related investigations and excavations. Archaeological investigations are divided into land investigations and water surface explorations. Combining the two, the site is initially divided into four areas: the Grand Pier, Wangjiangtai, Wudianzi, and Dashibao. Archaeological excavations have confirmed that there are cultural relics out of the cofferdam, but they can be roughly divided into two dense areas. Archaeological exploration emphasizes the combination of multi-source data and multiple methods. Direct detection is performed by magnetic method and induced polarization method, indirect detection is performed by resistivity method and amphibious radar, and then the detection data is fused and comprehensively interpreted. Information extraction emphasizes the collection of multi-dimensional data, and three-dimensional laser scanning is performed on the excavated area and water relics to obtain high-precision texture information. Through the processing of 3D point cloud data and images, the interaction of multidimensional and massive data is realized, and visualization programs are developed.
