摘要在早期的研究中，黑曜石安达瓦伊拉斯A和安达瓦伊拉斯B的化学类型是从阿普里马克省和邻近地区的Waywaka和其他地点回收的文物中确定的。本文报告了分别在Potreropampa和Lisahuacho地区发现的安达瓦伊拉斯A和安达瓦伊拉斯B的地质来源，并提供了源样品的仪器中子活化分析，以证明识别。波特雷罗潘帕水源和利萨瓦乔水源位于阿普里马克省查尔万卡镇西南部帕查查卡河支流的沿着。现有的证据表明，这两个来源主要是本地和区域的重要性，虽然少量的黑曜石从这些来源分布更广泛的早期地平线，中期地平线，和晚期地平线。
Abstract In earlier studies, the chemical types of obsidian Andahuaylas A and Andahuaylas B were identified from artifacts recovered at Waywaka and other sites in the Department of Apurimac and adjacent areas. This article reports the discovery of the geological sources of Andahuaylas A and Andahuaylas B in the zones of Potreropampa and Lisahuacho, respectively, and provides instrumental neutron activation analyses of the source samples to demonstrate the identification. The Potreropampa source and the Lisahuacho source are located along a tributary of the Pachachaca River to the southwest of the town of Chalhuanca in the Department of Apurimac. The evidence available suggests that these two sources were primarily of local and regional importance, although small quantities of obsidian from these sources were distributed more widely during the Early Horizon, Middle Horizon, and Late Horizon.
