Abstract—The paper reports petromagnetic and archeomagnetic studies of ceramic fragments of the Late Bronze and Early Iron ages from archeological sites of the Grishinskii Istok III, Tyukov gorodok, and Shishkino hillfort, which are located in the Oka River basin, Ryazan district, Russian Federation. In total, 43 determinations of geomagnetic field intensity were obtained for the time interval of 1500–400 B.C., including 10 determinations for ceramics of the Grishinskii Istok III, 11 determinations for ceramics of the Tyukov gorodok, and 22 determinations for ceramics of the Shishkino hillfort. The investigated time interval is characterized by the elevated values of the geomagnetic field intensity of 55–59 μT, which are much higher than the average field intensity for the Russian Plain in the IV–first half of III millennium B.C. Obtained VADM values for the central Russian Plain fall in a wide range of values obtained on the Georgian archeological sites located in the same longitudinal sector. A large scatter of data can be related both to the large error in ¹⁴C determination, which is comparable with the duration of the time intervals under investigation, and with the high velocity of magnetic field variations within this time interval.

俄罗斯平原中部青铜晚期和铁器早期考古陶瓷中记录的地磁场古强度变化

摘要/ abstract摘要:本文报道了在俄罗斯梁山区奥卡河流域的Grishinskii Istok III、Tyukov gorodok和Shishkino hillfort考古遗址中发现的青铜时代晚期和铁器时代早期陶瓷碎片的岩石磁和考古磁研究。共获得了公元前1500-400年间43次地磁场强度测定结果，其中格里欣斯基-伊斯托克3期陶瓷测定结果10次，秋科夫-戈罗多克陶瓷测定结果11次，什金诺丘陵陶瓷测定结果22次。研究时间间隔的特点是地磁场强度在55 ~ 59 μT之间升高，远高于俄罗斯平原在公元前四千年至公元前三千年上半叶的平均场强。俄罗斯平原中部的VADM值与位于同一纵向区域的格鲁吉亚考古遗址的VADM值的范围很广。数据的大分散可能与14C测定的大误差(与所研究的时间间隔的持续时间相当)以及该时间间隔内磁场变化的高速度有关。
