四川省文物考古研究院三星堆遗址工作站站长冉宏林介绍，碳14测年显示，3、4、6、8号祭祀坑埋藏年代大概率处于公元前1201年至公元 前1012年，相当于商代晚期，1、2、3、4、7、8号祭祀坑埋藏年代相同。该成果为厘清祭祀坑年代和构建遗址精细年代框架提供了重要依据。 研究显示，三星堆青铜铸造展现出独特的技术创新与本土化表达，形成了以分铸为核心，兼用浑铸、锻造的创新铸造技术体系；独特 的"芯骨-条形芯撑"技术，有效解决了细长、弯曲器物的成型难题。这一成果不仅深化了对中国古代青铜铸造体系的认知，也为揭示中华文明 多元一体及世界青铜器铸造技术的交流机制提供了新证据。 目前多学科团队已修复三星堆金器270余件，重逾1500克，三星堆8个祭祀坑出土的金器总重量约2000克，均为金银合金。三星堆出土玉璋 与二里头文化玉器有着密切的传承关系。三星堆先民确立了稻作农业为主体的农业形态，由此支撑了高密度人口，为三星堆古国的迅速崛起提 供了充足的保障与动力。同时，通过现场保护技术、脱水加固技术的研发和应用，3、4、7、8号祭祀坑出土的600余根饱水象牙能够在常规环 境下保存、展示。 9月27日，四川省文物考古研究院在四川德阳召开 ...

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].

Core Insights - The latest research from the Sichuan Provincial Institute of Cultural Relics and Archaeology reveals significant findings regarding the Sanxingdui site, including the dating of sacrificial pits and advancements in bronze and gold artifact production techniques [1][3][18]. 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 the burial dates range from 1201 BC to 1012 BC [5][10]. - The use of carbon-14 dating, particularly from selected bamboo charcoal, has provided a more precise dating, pinpointing it to around 1100 BC, approximately 3100 years ago [7][10]. - The discovery of cross-pit matching artifacts is crucial for understanding the chronological relationship and nature of the sacrificial pits, confirming they were buried during the same period [9]. Group 2: Bronze Casting Techniques - The "core-bone strip support" technique has been identified as a significant innovation in bronze casting, marking a unique aspect of Sanxingdui's craftsmanship [11][13]. - This technique allows for the creation of complex and large bronze artifacts, showcasing a distinct approach compared to the traditional mold casting methods used in other regions during the same period [15]. - The research indicates that the bronze artifacts from Sanxingdui represent a sophisticated casting technology that integrates multiple methods, including core casting and forging [13]. Group 3: Gold and Painted Bronze Artifacts - The research confirms that the painted bronze artifacts from Sanxingdui are among the earliest known lacquered copper wares in China, utilizing cinnabar and lacquer, establishing a cultural link between Sanxingdui and the Jinsha site [20]. - Analysis of the gold artifacts indicates that over 2 kilograms of gold were used, employing advanced techniques such as the "cupellation" method for purifying gold [20]. - The findings suggest that as early as the late Shang Dynasty, the ancient Shu people had developed intensive wetland rice agriculture and standardized pottery production, reflecting a prosperous society [20]. Group 4: Historical Context and Cultural Significance - 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 [23]. - The site experienced internal conflicts that led to the decline of its status as a central city, with evidence of warfare impacting its religious and social structures [24]. - The research highlights the interconnectedness of ancient Shu civilization with the Central Plains, emphasizing its role as a vital component of the diverse and unified Chinese civilization [17].
