Rural basilicas are the most important evidence of Christianization of the countryside on the island of Mallorca (Balearic Islands, Spain). Recent investigations of rural landscape transformations suggest that some churches were built along communication routes and linked to preexisting settlements. To obtain new data that could support this hypothesis, a geophysical survey has been carried out at the early Christian complex of Son Peretó, one of the most emblematic sites for the understanding of Late Antiquity on the island. The objective was to better define the site investigating the possible presence of other remains related to the Christian complex, that is undergoing excavation, or to a previous settlement that was later Christianized. The geophysical survey was carried out combining magnetometry and ground-penetrating radar. For the magnetic investigation, a multiprobe gradiometer array was used. GPR was used to examine the areas nearby the remains already excavated and to better define areas where the magnetic data revealed interesting anomalies. GPR data were collected using an IDS GPR system. The results revealed both the presence of architectural remains beneath the soil that help define the Early Christian complex, as well as other remains that suggest the church was part of a larger settlement.

Son Peretó（马略卡岛，巴利阿里群岛，西班牙）的早期基督教综合体的地球物理调查

乡村教堂是马略卡岛（西班牙巴利阿里群岛）乡村基督教化的最重要证据。最近对乡村景观转变的调查表明，一些教堂是沿着交通路线建造的，并与先前存在的定居点相连。为了获得可以支持这一假设的新数据，已在 Son Peretó 的早期基督教建筑群进行了地球物理调查，这是了解岛上古代晚期的最具象征意义的地点之一。目的是更好地定义该地点，以调查与正在挖掘的基督教建筑群或后来被基督教化的先前定居点有关的其他遗骸的可能存在。地球物理调查是结合磁力测量和探地雷达进行的。对于磁性调查，使用了多探头梯度计阵列。GPR 用于检查已挖掘遗迹附近的区域，并更好地定义磁性数据显示有趣异常的区域。GPR 数据是使用 IDS GPR 系统收集的。结果显示，土壤下存在有助于定义早期基督教建筑群的建筑遗迹，以及其他表明教堂是更大定居点一部分的遗迹。
