A previous use-wear and residue analysis of backed artefacts from Deep Creek Shelter showed that they had a range of functions and hadbeen used with a variety of raw materials. Were non-backed retouched flakes at Deep Creek used for different purposes? To answer thisquestion, 40 non-backed specimens were selected for microscopic use-wear and residue analysis. Not all of these non-backed artefacts hadbeen used, but we identified that many were scrapers, knives, incisors and saws. These tools were used for bone-working and wood-working,and possibly skin-working and non-woody plant-processing. Some of these non-backed retouched artefacts were hafted. For the first time,these results allow comparison of the tool use of backed and non-backed artefacts in Australia. At Deep Creek, the range of functions forthe non-backed component was extremely similar to that of the backed artefacts. Although both artefact categories displayed similar tooluse, they are distinguished in one interesting way: non-backed specimens were often single purpose, dedicated to one function, whereasbacked artefacts were often multifunctional and multipurpose. These results help us understand the structure of tool use in Australia

来自悉尼盆地 Deep Creek Shelter 的非背衬修饰人工制品的残留和使用磨损分析：对背衬人工制品作用的影响

先前对 Deep Creek Shelter 背衬手工艺品的使用磨损和残留物分析表明，它们具有多种功能，并已与多种原材料一起使用。Deep Creek 的无背胶修饰薄片是否用于不同目的？为了回答这个问题，选择了 40 个无背衬样品进行微观使用磨损和残留分析。并非所有这些无背衬的人工制品都被使用过，但我们发现其中许多是刮刀、刀具、门牙和锯子。这些工具用于骨加工和木材加工，可能还用于皮肤加工和非木本植物加工。其中一些未经修饰的人工制品被盗用。这些结果第一次允许对澳大利亚支持和非支持人工制品的工具使用进行比较。在深溪，非支持组件的功能范围与支持人工制品的功能范围极为相似。尽管两种人工制品类别都展示了类似的工具使用，但它们以一种有趣的方式进行区分：无支持的标本通常是单一用途的，专用于一种功能，而支持的人工制品通常是多功能和多用途的。这些结果有助于我们了解澳大利亚工具使用的结构
