This paper presents the carbon (¹³C/¹²C), nitrogen (¹⁵N/¹⁴N), oxygen (¹⁸O/¹⁶O), hydrogen (²H/¹H) and sulfur (³⁴S/³²S) stable isotope values measured in the hair of a female individual from north‐western Argentina. The analysis of segments of this tissue allows for the recording of the diet and migratory changes with a short time resolution. The sample is from a mummified young female individual discovered in Chuscha mount, Salta province. It was found at more than 5000 masl, in a mountain sanctuary of the Inca expansion (capacochas). The paper discusses the paleodiet and mobility patterns of this individual in the period before her death, focusing on the isotopic variations in a limited time scale. The results indicate that the individual moved from a different region to the place where she was sacrificed. Furthermore, in the last year the individual was alive, a shift in the isotopic composition of the food consumed is detected: a variation in the importance of C₄ over C₃ resources is evident. The results are compared with the isotopic estimations for other children and young people recovered in archaeological contexts associated with capacochas to infer variability in the geographical trajectories covered during their last months of life.

Nevado de Chuscha（阿根廷萨尔塔）的印加木乃伊的稳定同位素分析*

本文介绍了碳（¹³ C / ¹² C），氮（¹⁵ N / ¹⁴ N），氧（¹⁸ O / ¹⁶ O），氢（² H / ¹ H）和硫（³⁴ S / ³² S）稳定同位素在阿根廷西北部的女性个体的头发中测得的数值。该组织的各部分的分析允许以较短的时间分辨率记录饮食和迁徙变化。样本取自萨尔塔省楚沙山的木乃伊年轻女性个体。在印加扩展的一个山地圣地（capacochas）中发现了5000多马斯拉）。本文讨论了该人去世前的古生物学和活动性模式，重点研究了有限时间内的同位素变化。结果表明，该人从另一个地区搬到了她被牺牲的地方。此外，在该个体还活着的最后一年，发现了所食用食物的同位素组成发生了变化：C _4相对于C ₃资源的重要性发生了明显变化。将结果与在与capacochas相关的考古环境中恢复的其他儿童和年轻人的同位素估计值进行比较，以推断他们生命中最后几个月所涵盖的地理轨迹的变化性。
