A 2019 geophysical survey of part of the 8.55‐ha Freston interrupted ditch system (Suffolk), which integrated reconnaissance fluxgate gradiometry with earth resistance meter techniques, produced a fine‐grained geo‐spatial resolution site plan to undertake a pilot‐study research excavation. The features targeted comprised four ditch termini of the enclosure, with the aim being to test the long‐established hypothesis that the monument represented an Early Neolithic causewayed enclosure. Although the geophysical survey successfully located the ditch termini and linear trends indicative of the internal palisade trench, the magnetic data in particular further suggested the presence of numerous pit‐like anomalies both within and outside of the enclosure. The combined survey data also detailed for the first time an approximately 70‐m‐long curvilinear low‐resistance ditch‐like anomaly that appears to precede the interrupted ditch system. The working hypothesis is that this represents a ditch flanking a long barrow, a type of communal Early Neolithic mortuary monument that typically predate the construction of causewayed enclosures across southern Britain. The subsequent 6‐week excavation achieved its aims by recovering diagnostic Early Neolithic (earlier 4th millennium cal BC) material culture from the ditch fills.

在英国萨福克的弗雷斯顿早期新石器时代铜锣围墙中结合了地球物理勘测和开挖

2019年对8.55公顷弗里斯顿间断沟渠系统(Suffolk)的一部分进行了地球物理调查,该系统将侦察通量闸门梯度法与接地电阻仪技术相结合,产生了细粒度的地理空间分辨率站点计划,以进行试点研究开挖。目标特征包括围墙的四个沟渠终点,目的是检验由来已久的假说,即纪念碑代表早期新石器时代的围墙。尽管地球物理调查成功地确定了沟渠终点和指示内部木栅沟槽的线性趋势,但磁数据尤其进一步表明在围护内部和外部都存在许多类似坑的异常现象。合并的调查数据还首次详细说明了大约70米长的曲线低电阻沟状异常,该异常似乎早于间断沟系统之前。可行的假设是,这代表了一条长手推车两侧的沟渠,这是一种公共的新石器时代早期monument葬纪念碑,通常早于在英国南部建造堤道围墙之前。随后的6周开挖通过从沟渠填充物中恢复诊断出的新石器时代早期(公元前4世纪初期)材料文化来实现其目标。一种新型的新石器时代的公共太平间纪念碑,通常早于在英国南部修建堤道围墙之前。随后的6周开挖通过从沟渠填充物中恢复诊断出的新石器时代早期(公元前4世纪初期)材料文化来实现其目标。一种新型的新石器时代的公共太平间纪念碑,通常早于在英国南部修建堤道围墙之前。随后的6周开挖通过从沟渠填充物中恢复诊断出的新石器时代早期(公元前4世纪初期)材料文化来实现其目标。
