Soil colour spectra prehistoric pit

项目摘要

Prehistoric pits are filled with ancient topsoil material, which has been preserved there over millennia. A characteristic of these pit fillings is that their colour is different depending on the time the soil material was relocated. Soil colour is the result of soil forming processes and soil properties, and it could therefore indicate the soil characteristics present during that specific period. To the best of our knowledge, no investigation analysed and explained the reasons for these soil colour changes over time. The proposed project will investigate soil parameters from pit fillings of different archaeological periods in the loess area of the Lower Rhine Basin (NW-Germany). It aims to implement the measurement of colour spectra as a novel analytical tool for the rapid analyses of a high number of soil samples: the main goal is to relate highresolution colour data measured by a spectrophotometer to soil parameters that were analysed by conventional pedogenic methods and by mid infrared spectroscopy (MIRS), with a main focus on charred organic matter (BPCAs). This tool would enable us to quantify the variation of soil properties over a timescale of several millennia, during different prehistoric periods at regional scale and for loess soils in general. Detailed information concerning changing soil properties on a regional scale is necessary to determine past soil quality and it helps to increase our understanding of prehistoric soil cultivation practices. Furthermore, these information could also help to increase our understanding about agricultural systems in different archaeological periods.

史前坑中充满了古老的表土材料，这些材料已经保存了数千年。这些坑填料的一个特点是，它们的颜色因土壤材料迁移的时间而异。土壤颜色是土壤形成过程和土壤性质的结果，因此它可以指示特定时期存在的土壤特性。据我们所知，没有调查分析和解释这些土壤颜色随时间变化的原因。拟议项目将调查莱茵河下游盆地（德国西北部）黄土地区不同考古时期坑填料的土壤参数。其目的是将色谱测量作为一种新的分析工具，用于快速分析大量土壤样品：主要目标是将分光光度计测量的高分辨率颜色数据与通过传统成土方法和中红外光谱分析的土壤参数相关联，主要侧重于烧焦的有机物。这一工具将使我们能够量化土壤性质的变化，在几千年的时间尺度，在不同的史前时期在区域尺度和一般的黄土。关于区域范围内土壤性质变化的详细信息对于确定过去的土壤质量是必要的，它有助于增加我们对史前土壤耕作实践的理解。此外，这些信息也有助于增加我们对不同考古时期农业系统的了解。
