Dating the construction of dry-stone walls is challenging since such structures are typically built without any mortar that can be used for dating. Rock surface luminescence dating is a developing dating method that could advance chronological insights from structures constructed using dry-stone techniques. This study explores rock surface luminescence dating by targeting dry-stone walls from two enclosure complexes and a hut located in the pastoral upland landscape in Val di Sole, Italy. Gneissic rocks were collected from the dry-stone walls, including surfaces that were either exposed or covered (buried) during the time of sampling. Their respective exposure and burial histories were investigated by measuring the luminescence intensity in feldspar minerals from polymineral rock slices. From covered rock surfaces from one enclosure complex, we calculated recent burial ages ($\backsim$200 a) from one rock, and burial of $\backsim$500 a (bottom surface) and 3750 ± 660 a (top surface) from a second rock. The top surfaces of two additional rocks date the construction of an adjacent hut to the Early Middle Ages. The luminescence-depth profile from one such rock has a complex exposure and burial history, including events that predate the hut’s construction. Fitted exposure ages from a second enclosure complex suggest with significant errors either a recent age (<10 a) or construction during the 19th century AD. Burial dating using rock surface luminescence dating appears feasible for dry-stone walls provided that the rock surface was sufficiently exposed before being incorporated into the structure; here, the gneissic surfaces were bleached to depths of $\backsim$0-2 mm before the last burial. Contrariwise, exposure dating generally underestimates the expected age. The variation in ages observed from our rock surfaces indicates that the degree of preservation of the wall, the position of the rock, erosion, and knowledge regarding the general archaeological setting are essential to interpreting the estimated ages. In this study, rock surface luminescence dating provides new, previously inaccessible chronological data with implications for interpreting human activities in the alpine areas of Val di Sole.

对干石墙的建造进行测年具有挑战性，因为这种结构通常是在没有任何可用于测年的砂浆的情况下建造的。岩石表面发光测年是一种发展中的测年方法，可以从使用干石技术建造的结构中推进年代学见解。本研究通过针对位于意大利 Val di Sole 田园高地景观中的两个围护建筑群和一间小屋的干石墙来探索岩石表面发光测年。从干石墙收集片麻岩，包括在采样期间暴露或覆盖（掩埋）的表面。通过测量来自多矿物岩石切片的长石矿物的发光强度，研究了它们各自的暴露和埋藏历史。从一个封闭综合体的覆盖岩石表面，$\backsim$200 a) 从一块岩石中埋葬 $\backsim$500 a（底部表面）和 3750 ± 660 a（顶部表面）从第二块岩石。另外两块岩石的顶部表面可以追溯到中世纪早期相邻小屋的建造。一块这样的岩石的发光深度剖面具有复杂的暴露和埋藏历史，包括小屋建造之前的事件。来自第二个围墙复合体的拟合暴露年龄表明最近年龄（<10 a）或公元 19 世纪的建筑存在重大错误。使用岩石表面发光测年的埋葬测年对于干石墙似乎是可行的，前提是岩石表面在被纳入结构之前充分暴露；在这里，片麻岩表面被漂白到 $\backsim$最后一次埋葬前0-2毫米。相反，暴露约会通常会低估预期年龄。从我们的岩石表面观察到的年龄变化表明，墙壁的保存程度、岩石的位置、侵蚀以及有关一般考古环境的知识对于解释估计的年龄至关重要。在这项研究中，岩石表面发光测年提供了新的、以前无法获得的年代数据，这些数据对解释 Val di Sole 高山地区的人类活动具有重要意义。
