祭祀坑年代确定为商代晚期 有何意义？ 四川省文物考古研究院发布了三星堆遗址多学科研究最新成果。三星堆祭祀坑埋藏年代是否确定？三星堆青铜器铸造有何独特的技术？三星堆出土的金器制 作技术、铜器彩绘工艺有哪些新发现？ 三星堆祭祀坑的年代问题一直是学界和社会公众关注的焦点。此次研究通过碳十四年代测定等技术，明确祭祀坑埋藏年代为商代晚期，这有什么重要意义 呢？ 通过碳十四年代测定，三号、四号、六号、八号祭祀坑埋藏年代有95.4%的概率处于公元前1201年至公元前1012年，相当于商代晚期。 四川大学文科讲席教授 李水城：北京大学做了一个非常精确标本精选，从坑里边儿挑拣成的木炭，专门挑竹子的，测的年代就更加精确，为什么？因为竹 子的生长年代短，从这个角度来讲，新的测年就是把它定在了公元前的1100年，也是距今3100年，往前拉一点（距今）3200年。 四川省文物考古研究院三星堆遗址工作站站长 冉宏林：准确获取了祭祀坑的精确年代，这是一个填补空白的重要发现。祭祀坑年代的确定，对我们去进一 步认识古蜀文明它的一个演进和华夏化的进程也是非常关键的。 一、二、三、四、七、八号坑中发现的跨坑拼对器物，对确定祭祀坑的年代关系和性质十 ...

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].
