Floodplain wetlands are complex systems influenced by many natural and anthropogenic operators. Due to the influence of high and varying groundwater table and high organic contents, geophysical prospection in wetland floodplains quickly reaches the limits of its effectiveness. At the Early Medieval canal Fossa Carolina in southwest Germany, a study design employing magnetometry, drillings, sampling, and in situ rock magnetic measurements was used for environmental magnetic interpretation of magnetic anomalies in magnetograms and sediment layers. This approach offers reliable archaeological interpretation of magnetic anomalies and magnetic properties under the site specific sedimentological conditions of a floodplain wetland. It was also found that man‐made magnetic anomalies in the floodplain are due to the genesis of different remanent magnetizations – specifically, greigite (Fe₃S₄) can cause distinct magnetic anomalies in floodplains that can be recognized readily in surface magnetic data.

卡罗来纳州福沙平原湿地的磁性异常和考古沉积物磁性的成因

洪泛区湿地是受许多自然和人为因素影响的复杂系统。由于地下水位高低变化和有机物含量高的影响，湿地洪泛区的地球物理勘探很快达到了其有效性的极限。在德国西南部的中世纪早期运河卡罗莱纳州卡萨罗纳州，采用磁力分析，钻孔，采样和原位研究设计岩石磁测量用于环境磁解释磁图和沉积物层中的磁异常。这种方法为洪泛区湿地的特定地点沉积条件下的磁异常和磁特性提供了可靠的考古学解释。我们还发现，漫滩中的人为磁异常是由于不同的剩余磁化强度所引起的，特别是，钙铁矿（Fe ₃ S ₄）会引起漫滩中明显的磁异常，这些磁异常可以在表面磁数据中轻松识别。
