Electromagnetic induction (EMI) has been used in archaeology for decades, but still lags in use and development when compared to magnetometry and ground‐penetrating radar. While it has become more popular than electrical resistivity area survey, it is now less commonly used than electrical resistivity tomography. The EMI method is likely underutilized due to drift problems and a lack of multi‐sensor, vehicle‐towed systems capable of rapid, high‐density data collection. In this article we demonstrate not only the effectiveness of EMI survey, but a case where entire villages would have remained undetected without it. At the Singer‐Hieronymus Site in central Kentucky, USA, a vehicle‐towed frequency domain EMI survey detected the location of plazas, residential areas, and trash disposal areas across multiple Fort Ancient villages that contained both intact and heavily disturbed deposits. Additionally, three new villages were revealed. Through this process, we discovered how Fort Ancient village dynamics may be studied through a geophysical investigation of village shape, size, and spatial organization.

频域电磁感应：调查古堡村庄动态的有效方法

电磁感应（EMI）在考古学中已经使用了数十年，但与磁力测量法和探地雷达相比，其使用和开发仍然滞后。尽管它已经比电阻率区域调查更受欢迎，但现在比电阻断层扫描术更不常用。由于漂移问题以及缺乏能够快速，高密度数据收集的多传感器，车载系统，EMI方法可能未得到充分利用。在本文中，我们不仅展示了EMI调查的有效性，而且还展示了如果没有它，整个村庄都将无法被发现的情况。在美国肯塔基州中部的Singer-Hieronymus站点，进行了一次车辆拖曳的频域EMI调查，发现了广场，居民区，以及遍布古堡的多个村庄中的垃圾处理区，这些村落既保存完好又造成严重破坏的沉积物。此外，还发现了三个新村庄。通过这个过程，我们发现了如何通过对村庄的形状，大小和空间组织进行地球物理研究来研究古堡的村庄动态。
