对鹿儿岛县和南西诸岛的五座定年火山的熔岩流和火山碎屑流进行了磁化强度测量。交变磁场和热退磁实验表明，从这些熔岩和火山碎屑流标本保持稳定的剩磁。55个取样点的平均方向根据每个地点使用磁通门型磁力计测得的当地磁倾和倾角值进行了校正。建立了一条新的九州南部长期变化曲线，并将其应用于一些年龄未知的熔岩流的年龄测定。
The remanent magnetization of lava and pyroclastic flows from five dated volcanoes in Kagoshima Prefecture and Nansei Islands were measured. Alternating field and thermal demagnetization experiments reveal that specimens from these lava and pyroclastic flows preserve a stable remanent magnetization. The site mean directions of 55 sampling sites were corrected for the local magnetic declination and inclination values measured using a fluxgate type magnetometer at each locality. A new secular variation curve for South Kyusyu is established and applied for the age determination of some lava flows with unknown ages.
