| 摘 要： | 地幔运动受到地球自转的强烈影响。通过简化计算推导出地幔运动的轨迹是一条螺旋曲线。将共同运动的地幔团块称"幔团（mantlemass）",井分析了运动的幔因造成上覆岩石圈中的内力和应力。最后认为幔四运动是构造运动及地幔流体成矿的主要原因。

A NEW UNDERSTANDING OF MANTLE MOTION:MANTLEMASS SPIRAL MOTION |
| |
| Abstract: | Mantle motion is sharply affected by rotation of the earth, whose locus was samplized deduced as a spiral curve. The mantle group moved consistently may be called "mantlemass", and the internal forces and stresses in the lithosphere caused by mantlemass motion are calculated. Lastly, it is suggested that mantlemass motion is the principal cause of tectonic movement and mantle-fluid metallogenesis. |
