| 摘 要： | 讨论了考古标本中所含矿物的磁学性质与古代地球磁场强度测定数据可靠性之间的关系，进行了岩石磁学实验，包括高温、低温磁化率测定、居里温度测定、磁滞回线各参数的测定等．结果表明，文中所用各类标本（陶片、砖、烧土等）的主要载磁矿物为磁铁矿，采用这些标本用Ｔｈｅｌｌｉｅｒ方法进行逐步热退磁实验所测定的古强度数据较为可靠．

| Abstract: | Author telated the mineral magnetic properties of some archeological samples tothe quality of the paleointensity data that they produce. Therefore, the dineral magneticproperties of the samples (potsherds, bricks, baked clays ets.) were investigated usingseveral techniques, including suscephbility variations from low temperature (about- 2000 ) tO room temperature, Curie temperature, hysteresis measurements and so on.The results show: the magnetite was identified as the predominant camer ofmagnehzation in the samples; those samples can produce high-quality paleointensitydata obtained by Thellier method of stepwise thermal demagnehzation. |
