加速器质谱法（AMS）放射性碳测年技术的进步使得通过对颜料本身进行采样来确定史前洞穴壁画的年代成为可能，而不是依赖于从绘画附近发现的各种史前遗迹中获得的日期。气候与环境科学博物馆（LSCE）的工作集中在法国南部和西班牙北方的史前木炭洞穴壁画上。在大多数洞穴中，颜料样本是从几幅画中收集的，在某些情况下，样本量允许对同一人物进行多次独立测量，以便可以测试计算日期的一致性。在确定日期之前，每个样品都经过热处理，然后进行强度与样品大小相称的酸和碱处理。九个野牛图纸从三个洞穴在西班牙的坎塔布里亚地区-两个从Covaciella，三个从阿尔塔米拉，四个从埃尔卡斯蒂略-进行了采样和日期。这27个日期介于13，000和14，500 BP之间，使我们能够将这些图纸归因于Magdalenian时期。Cosquer洞穴中13幅绘画的24个日期表明了两个不同的绘画活动时期-一个大约28，000 BP，另一个大约19，000 BP。肖维洞穴壁画被证明是迄今为止最古老的记录，因为五个日期在32，000到31，000 BP之间。在更详细地讨论了样品制备方案之后，我们将讨论获得的年龄，并将其与其他年代学数据进行比较。
Advances in radiocarbon dating by accelerator mass spectrometry (AMS) have made it possible to date prehistoric cave paintings by sampling the pigment itself instead of relying on dates derived from miscellaneous prehistoric remains recovered in the vicinity of the paintings. The work at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE) concentrated on prehistoric charcoal cave paintings from southern France and northern Spain. In most caves, pigment samples were collected from several paintings, and in some instances the sample size allowed for multiple independent measurements on the same figure, so that the coherence of the calculated dates could be tested. Before being dated, each specimen was subjected to a thermal treatment preceded by an acid and basic treatment of intensity commensurate with the sample size. Nine bison drawings from three caves in the Cantabrian region of Spain—two from Covaciella, three from Altamira, and four from El Castillo—were sampled and dated. The 27 dates fell between 13,000 and 14,500 BP, allowing us to attribute the drawings to the Magdalenian period. The 24 dates for 13 drawings in the Cosquer cave indicated two distinct periods of painting activity—one around 28,000 BP and the other around 19,000 BP. The Chauvet cave paintings turned out to be the oldest recorded to date, as five dates fell between 32,000 and 31,000 BP. After discussing the sample preparation protocol in more detail, we will discuss the ages obtained and compare them with other chronological data.
