利用现代和考古地点对土房地板进行了化学分析的试点研究，以确定活动留下可检测的化学残留物的程度，以及这些残留物是否保存在考古环境中。其目标是发展鉴定和解释考古结构活动区域的技术，并确定哪些因素有助于区分活动。一个来自墨西哥瓦哈卡州的现代建筑和两个考古房屋楼层（加拿大不列颠哥伦比亚省和墨西哥瓦哈卡州）进行了研究。从三个地点的地面采集土壤样品，并通过电感耦合等离子体原子发射光谱（ICP/AES）分析Al、Ba、Ca、Fe、K、Mg、Mn、Na、P、Sr、Ti和Zn。初步结果表明，可以很容易地根据土壤中的化学残留物来区分现代住宅小区的活动区，考古特征在化学上与自然土壤不同，地板和壁炉等特征可以相互区分，也可以与自然史前地面区分开来。与传统的单元素分析相比，ICP/AES的多元素表征具有优势，可以以更少的精力、费用和时间获得更多有用的数据。
A pilot study on the chemical analysis of earthen house floors, using both modern and archaeological localities, was undertaken to determine the degree to which activities leave detectable chemical residues, and whether these residues are preserved in archaeological contexts. The goals were to develop techniques for the identification and interpretation of activity areas in archaeological structures and to determine which elements serve to distinguish activities. One modern structure from Oaxaca, Mexico and two archaeological house floors (ii-om British Columbia, Canada and Oaxaca, Mexico) were studied. Soil samples were collected from floors at all three sites and analysed by inductively coupled plasma-atomic emission spectroscopy (ICP/AES) for Al, Ba, Ca, Fe, K, Mg, Mn, Na, P, Sr, Ti, and Zn. Preliminary results show that activity areas in the modern house compound can readily be distinguished on the basis of chemical residues in soils, that archaeological features are chemically distinct from natural soils, and that features such as floors, and hearths can be distinguished from each other and from the natural prehistoric ground surface. Multi-element characterization by ICP/AES offers an advantage over traditional, single element analysis by yielding more useful data for less effort, expense, and time.
