The Osmore Drainage of southern Peru has a long and rich history of human occupation. While the utility of stable oxygen and radiogenic strontium isotope values in identifying paleomobility between this region and population centers in the Bolivian altiplano has been well established, many questions about intra-regional mobility remain. To better understand how these methods can be used to detect localized residential mobility, we present new δ¹⁸O_mw(VSMOW) and ⁸⁷Sr/⁸⁶Sr values from water, soil, plant, and faunal samples. Samples were collected primarily from traditionally farmed agricultural fields in the upper, middle, and lower Osmore Drainage. Results are indiscernible between the upper and middle drainage, while marine contribution to the lower drainage produces distinct values. We discuss the methodological limitations and implications of our results for the use of stable oxygen and radiogenic strontium isotope analyses for intra-regional paleomobility studies in the Osmore Drainage.

秘鲁南部的奥斯莫尔（Osmore）排水道有着悠久而丰富的人类占领历史。虽然稳定氧和放射性锶同位素值在确定该地区与玻利维亚高原人口中心之间的古迁移率方面的效用已得到公认，但仍存在许多有关区域内迁移率的问题。为了更好地理解这些方法如何可以用来检测本地化的居住迁移，我们提出了新的δ ¹⁸ Ø _{MW（VSMOW）}和⁸⁷锶/ ⁸⁶水，土壤，植物和动物样本中的Sr值。样品主要是从奥斯莫尔河上游，中和下游的传统农业田地中采集的。上排水和中排水之间的结果是不明显的，而海洋对下排水的贡献产生了不同的值。我们讨论了使用稳定的氧气和放射性锶同位素分析进行​​奥斯莫尔地区排水区域内古迁移率研究的方法学局限性和结果的意义。
