板块运动的纬向重力模式

按照“纬向正常密度假说”的观点提出了“纬向密度异常”和“纬向重力”的概念,进而提出了板块运动的“纬向重力模式”,按照这一模式,纬向重力总是把地球物质从“纬向密度异常高”的地区推向、纬向密度异常低！”的地区,一方面,,纬向重力驱动岩石圈沿水平方向运动,另一方面,因纬向重力驱动软流圈物质沿水平方向运动而使得岩石圈沿垂直方向发生,同密度异常高地区的岩石圈会因软流圈物质的流失而下沉,纬向密度异常低地区的岩石圈会因为软流圈物质的补充而上升。

Latitudinal Gravity Mode of Plate Movement

This paper presents the concept of "latitudinal density anomaly"and"latitudinal gravity"on the basis of viewpoint of"latitudinal normal density hypothesis",and then,puts forward a"latitudinal gravity mode of plate movement".According to this mode,latitudinal gravity always pushes the earth's matter toward the region of"latitudinal density anomaly low"from"latitudinal density anomaly high".On one hand,latitudinal gravity drives lithosphere movement along the horizontal direction.On the other hand,because latitudinal gravity drives asthenosphere matter movement along the horizontal direction,it enables the lithosphere to move along the vertical direction;lithosphere in the region of latitudinal density anomaly high will subside due to loss of asthenosphere matter,but lithosphere in the region of latitudinal density anomaly low will rise because of adding the asthenosphere matter.
