Nuraghe S'Urachi is a monumental architectural complex in West Central Sardinia that was probably first built in the Bronze Age and remained occupied continuously into the early Roman Imperial period. It has been the object of systematic and large-scale archaeological investigations in three different phases since 1948 when the first excavations revealed a complex building within a massive defensive wall and multiple towers. Intermittent fieldwork between the 1980s and 2005 subsequently showed that the central nuraghe might comprise up to five principal towers. In 2013, a new collaborative research project, sponsored by Brown University and the Municipality of San Vero Milis, brought together a multidisciplinary research project to investigate this important archaeological site. In this framework, multi-frequency and multi-coil electromagnetic measurements (FDEM) and Electrical resistivity tomography (ERT) were carried out in 2018, 2019, and 2020, over and close to the nuraghe towers, to gain a better understanding of the inner part of the main structure and to investigate the surrounding area that was intensively settled in Phoenician and Punic times. The preliminary results of the geophysical measurements provide new and interesting evidence that supports new hypotheses and suggests possible future archaeological and geophysical strategies to investigate the unexcavated part of the archaeological site of S'Urachi.

Nuraghe S'Urachi（撒丁岛中西部）考古勘探的 FDEM 和 ERT 测量

Nuraghe S'Urachi 是撒丁岛中西部一座具有纪念意义的建筑群，可能最初建于青铜时代，并一直持续到罗马帝国早期。自 1948 年首次挖掘发现一座巨大的防御墙和多座塔楼内的复杂建筑以来，它一直是三个不同阶段的系统和大规模考古调查的对象。1980 年代和 2005 年之间的间歇性实地调查随后表明，中央 nuraghe 可能包括多达五个主要塔楼。2013 年，由布朗大学和圣维罗米利斯市赞助的一项新的合作研究项目汇集了一个多学科研究项目，以调查这个重要的考古遗址。在这个框架下，2018 年、2019 年和 2020 年，在 nuraghe 塔上方和附近进行了多频率和多线圈电磁测量 (FDEM) 和电阻率断层扫描 (ERT)，以更好地了解主塔的内部结构并调查在腓尼基和布匿时代集中定居的周边地区。地球物理测量的初步结果提供了新的和有趣的证据，支持新的假设，并提出了未来可能的考古和地球物理策略来调查 S'Urachi 考古遗址的未挖掘部分。为了更好地了解主体结构的内部，并调查腓尼基和布匿时代集中定居的周边地区。地球物理测量的初步结果提供了新的和有趣的证据，支持新的假设，并提出了未来可能的考古和地球物理策略来调查 S'Urachi 考古遗址的未挖掘部分。为了更好地了解主体结构的内部，并调查腓尼基和布匿时代集中定居的周边地区。地球物理测量的初步结果提供了新的和有趣的证据，支持新的假设，并提出了未来可能的考古和地球物理策略来调查 S'Urachi 考古遗址的未挖掘部分。
