Core Insights - The latest research from the Sichuan Provincial Institute of Cultural Relics and Archaeology confirms the burial date of the Sanxingdui sacrificial pits as the late Shang Dynasty, specifically between 1201 and 1012 BC, with a 95.4% probability [1][3] - The research highlights the significance of this dating in understanding the evolution of ancient Shu civilization and its integration into the broader Chinese cultural context [1] Group 1: Dating of Sacrificial Pits - The sacrificial pits' dating has been a focal point for both academia and the public, with new carbon dating techniques providing precise results [1] - The use of bamboo charcoal for dating has led to a more accurate determination of the pits' age, pinpointing it to around 1100 BC, approximately 3100 years ago [1] - The confirmation of the pits' age is considered a crucial discovery that fills a significant gap in the understanding of ancient Shu civilization [1] Group 2: Bronze Casting Technology - The research introduces the "core-bone-strip support" technique, which plays a vital role in the casting of large bronze artifacts [4] - This technique has been systematically confirmed for the first time in domestic archaeological sites from the same period, indicating a unique innovation in bronze casting [6] - The bronze artifacts from Sanxingdui represent a distinctive technological system that combines core casting with other methods, showcasing a unique bronze culture that is closely linked to the Central Plains civilization [6] Group 3: Gold and Painted Bronze Artifacts - Significant findings include the confirmation that Sanxingdui painted bronze artifacts are among the earliest known lacquered bronze wares in China, using cinnabar and lacquer [9] - Analysis of the gold artifacts indicates that over 2 kilograms of gold were used, employing advanced techniques for purification [9] - The discoveries also suggest that the ancient Shu people had developed intensive wetland rice agriculture and standardized pottery production by the late Shang Dynasty, reflecting a prosperous society [9]

Core Insights - The latest multidisciplinary research results from the Sanxingdui site have been released by the Sichuan Provincial Institute of Cultural Relics and Archaeology, focusing on the dating of sacrificial pits, unique bronze casting techniques, and new findings in gold and copper artifacts [1][3]. Group 1: Dating of Sacrificial Pits - The dating of the sacrificial pits has been confirmed to the late Shang Dynasty, with a 95.4% probability that pits No. 3, 4, 6, and 8 date between 1201 BC and 1012 BC [5][9]. - The precise dating is significant for understanding the evolution of ancient Shu civilization and its integration into the broader Chinese cultural context [9][3]. - The research utilized carbon-14 dating, with a focus on bamboo charcoal for more accurate results, pinpointing the date to around 1100 BC, approximately 3100 years ago [7][5]. Group 2: Bronze Casting Techniques - The "core-bone and strip core support" technique has been identified as a significant innovation in large bronze casting, marking its first systematic confirmation in domestic archaeological contexts [13][11]. - This technique is compared to the traditional model method used in ancient Chinese bronze casting, showcasing unique local adaptations that contributed to a distinctive bronze culture [15][11]. - The research indicates that the bronze artifacts from Sanxingdui were created using a combination of casting methods, including split casting, which reflects a sophisticated technological system [13][15]. Group 3: Gold and Copper Artifacts - The research confirms that the painted bronze artifacts from Sanxingdui are among the earliest known lacquered copper wares in China, establishing a cultural link between the Sanxingdui and Jinsha sites [19][17]. - Analysis of the gold artifacts indicates that over 2 kilograms of gold were used, employing advanced refining techniques [19][17]. - The findings suggest that the ancient Shu people had developed intensive wetland rice agriculture and standardized pottery production by the late Shang Dynasty, indicating a prosperous society [19][17]. Group 4: Historical Context and Cultural Evolution - The Sanxingdui site represents a long-lasting and extensive archaeological site, encompassing multiple cultural phases, including Baodun, Sanxingdui, and Shierqiao cultures, with significant developmental relationships among them [22][23]. - The Baodun culture period saw the construction of city walls due to resource competition, leading to a landscape of competing settlements [22][23]. - The transition of Sanxingdui from a central state capital to a regular city involved conflicts over capital status, resulting in significant changes to the urban structure and religious practices [23][22].
