对日本中部关东山脉赤壁盆地早中新世海相沉积物进行了古地磁测量。平均古地磁方向D=94°，I=53°(α95=8.3°)表明关东山脉自中中新世以来纬度变化不大，而是顺时针旋转约90°。这种旋转可以用日本海的打开和坦泽地块的碰撞来解释。
Paleomagnetic measurements were made on the early Miocene marine sediments in the Chichibu Basin of the Kanto Mountains, Central Japan. The mean paleomagnetic direction, D=94°, I=53° (α95=8.3°), indicates that the Kanto Mountains have not changed their latitude significantly, but have rotated clockwise through about 90° since the middle Miocene. The rotation can be explained by the opening of the Japan Sea and the collision of the Tanzawa Block.
