埃兰兹湾洞穴 (EBC) 是南非的一个重要遗址，可以讨论从上暴雪期到全新世发生的技术变革和适应。 2011 年，我们开展了一项新的实地考察活动，旨在澄清罗伯格在该地点最早的职业的性质和年代顺序，该地点是一个技术综合体，其外观与末次盛冰期密切相关。我们的结果记录了 Robberg 技术在大约 1997 年的出现。 19 398–18 790 cal BP，继通常被称为早期晚期石器时代的阶段之后。在本文中，我们通过对 EBC（距今 14 605-14 278 年）的 MOS1 石器组合进行技术和功能研究，进一步发展了 Robberg 的定义。我们的结果表明，除了从 30 公里以上的距离引入的经过热处理的硅混凝土之外，EBC 居住者主要选择了当地的石英。罗伯格居民采用了不同的减少策略，结合了双极/砧和软石锤敲击。还原序列旨在生产一组小型人工制品（< 25 毫米长），这些人工制品通常可归类为小叶片。修饰形式的发生率低，几何形状的缺失，加上我们的功能研究，证明了灵活的复合微石技术。我们还讨论了 EBC Robberg 居民的原材料供应策略，并提出了组合内和组合间变异性的问题。最后，我们尝试讨论其时间趋势，并在其他晚更新世细石器传统的背景下得出罗伯格技术的独创性。
Elands Bay Cave (EBC) is a key South African site allowing discussion of technological change and adaptations that occurred from the Upper Pleniglacial to the Holocene. In 2011, we set out a new field campaign aiming to clarify the nature and chronology of the earliest Robberg occupations at the site, a technocomplex whose appearance closely relates to the Last Glacial Maximum. Our results document the appearance of the Robberg technology at ca. 19 398–18 790 cal BP, succeeding a phase commonly referred to as the Early Later Stone Age. In this paper, we further develop the definition of the Robberg by providing a technological and functional study of the MOS1 lithic assemblage at EBC, dated to 14 605–14 278 cal BP. Our results show that EBC occupants dominantly selected local quartz in addition to heat-treated silcrete that was introduced from distances greater than 30 km. Robberg inhabitants applied different reduction strategies combining bipolar/anvil and soft stone hammer percussion. Reduction sequences were oriented toward the production of a set of small artefacts (< 25 mm long) that can be generically classified as bladelets. The low incidence of retouched forms and the absence of geometrics, together with our functional study, testify to a flexible composite microlithic technology. We also discuss the raw material provisioning strategies of EBC Robberg inhabitants and develop the question of the intra- and inter-assemblages variability. Finally, we attempt to discuss its temporal trends and conclude on the originality of the Robberg technology within the context of other Late Pleistocene microlithic traditions.
