According to the classical chronology of the Inca State, the ascension to power of Pachacuti Inca took place around AD 1438 and the construction of Machu Picchu began by AD 1450–1460. However, the improvement in the accuracy of radiocarbon (14C) dating resulting from the application of Bayesian analysis has changed our view of the historical chronology. This new research raises questions about our understanding of the cultural development of the Machu Picchu area, in the light of the new proposed chronological scheme. This paper presents a set of 11 new 14C dates, derived from AMS, from the sites of Llaqta of Machu Picchu, Chachabamba, and Choqesuysuy. The latter two sites are situated within the Machu Picchu National Archaeological Park (Arqueología del Santuario Histórico Nacional y Sitio Patrimonio Mundial de Machu Picchu) and have been interpreted as being part of the contemporary Late Horizon Inca landscape. The new 14C ages are modeled using Bayesian inference and present a revised dating framework for these sites and their chronological relationship with Llaqta of Machu Picchu.

印加人何时建立马丘比丘及其卫星站点？基于放射性碳测年的新方法

根据印加国家的古典年表，Pachacuti Inca 的权力提升发生在公元 1438 年左右，马丘比丘的建造始于公元 1450-1460 年。然而，放射性碳准确度的提高（14C) 应用贝叶斯分析产生的年代学改变了我们对历史年表的看法。根据新提出的时间顺序，这项新研究对我们对马丘比丘地区文化发展的理解提出了质疑。本文介绍了一组 11 个新的14C 日期，源自 AMS，来自马丘比丘的 Llaqta、Chachabamba 和 Choqesuysuy。后两个遗址位于马丘比丘国家考古公园（Arqueología del Santuario Histórico Nacional y Sitio Patrimonio Mundial de Machu Picchu）内，被解释为当代晚期地平线印加景观的一部分。新的14C 年龄使用贝叶斯推理进行建模，并为这些地点及其与马丘比丘的 Llaqta 的时间顺序关系提供了一个修订的约会框架。
