地磁

Paleomagnetic measurements demonstrate that the Jijiagou section which is the stratotype one of Baode Stage of the Neogene in China records 12 normal and 11 reversed polarity zones.

古地磁测量表明,国新近系保德阶界线层型,山西保德冀家沟剖面记录了12个正极性段与11个负极性段。

Besides, We indicated the main adavantages of this means and probable way of overcoming its shortage, that is, method of difference value of isoporic lines is used to process data of some stations.

另,指出了该手段要优及克服其可能途径,即有些台站可采用地磁等变线差值法处理。
