Archaeological deposits build up inside standing buildings both under and between floors and these have the potential to provide considerable information about human behavior in the past. Under and between floor spaces provide a unique depositional environment that allow the survival of rare and fragile organic materials that typically do not survive in other archaeological contexts, including paper, cardboard, fabric and other fibres, seeds, leather, and human hair and skin cells. However, they require a clear understanding of depositional processes to allow their interpretation. Experimental archaeology was conducted to understand the process of artifact deposition and the interpretation of underfloor deposits in twelve standing buildings in Western Australia. Floors were built and a range of artifacts swept across them to determine how artifacts travelled across floorboards or fell through gaps between boards. Size, shape, and angularity of artifacts were key determinants of the likelihood of deposition. Sweeping activity makes it more likely that material will be deposited around the margins of rooms, and particularly, to either side of doorways. Underfloor deposits excavated from two specific Western Australian buildings, Ellensbrook Homestead, and the York Residency Museum, are interpreted based on the results of these experiments.

考古沉积物堆积在楼层之下和楼层之间的直立建筑物内部，这些潜力有可能提供有关过去人类行为的大量信息。地板空间的下面和之间提供了独特的沉积环境，使稀有和易碎的有机材料得以生存，而这些稀有和有机材料通常无法在其他考古环境中生存，包括纸张，纸板，织物和其他纤维，种子，皮革以及人的头发和皮肤细胞。但是，他们需要对沉积过程有清楚的了解，才能对其进行解释。进行了实验考古，以了解人工沉积物的过程以及西澳大利亚州12座直立建筑物中地下沉积物的解释。建造了地板，并扫过了许多工件，以确定工件是如何穿过地板或穿过木板之间的缝隙掉落的。伪影的大小，形状和角度是决定沉积可能性的关键因素。清扫活动使物料更有可能沉积在房间的边缘周围，尤其是在门廊的两侧。根据这些实验的结果，对从两座西澳州特定建筑物Ellensbrook Homestead和York York Residency Museum挖掘的地下沉积物进行了解释。特别是在门口的任一侧 根据这些实验的结果，对从两座西澳州特定建筑物Ellensbrook Homestead和York York Residency Museum挖掘的地下沉积物进行了解释。特别是在门口的任一侧 根据这些实验的结果，对从两座西澳州特定建筑物Ellensbrook Homestead和York York Residency Museum挖掘的地下沉积物进行了解释。
