华北陆台早前寒武纪地质演化与地幔对流模式

提出了华北陆台早前寒武纪地质演化及地幔地流模式，太古宙地幔呈南北方向向陆台俯冲，由于放射性热元素在壳下的不断积累，温度逐渐升高，对流速度减慢，从而使地幔对流方向在晚太古代至早元古代发生了转换，由近南北向的挤压俯冲转米为近东西向的壳下地幔下涌，陆台下发生了广泛的ＴＴＧ质重熔，并发生了大幅度的抬升，这种对流状态持续到古生代末。

The Geological Evolution and Mantle Convection of the North China Platform in Early Precambrian

The Archean mantle subducted to the North China Platform from south to north and from north to south,generated Archean volcanic rocks in the form similar to the present island arc environment and formed the paleostructural lines spreading east to west. On account of the accumulation of large amounts of heat-generating radioactive elements under the platform,the temperature at the lower part of the Platform was increased,the convection velosity of the mantle was decreased gradually,and at last stopped in the early Proterozoic era. In the Proterozoic,the Platform was uplifted considerably,the direction of mantle convection was changed from south-north subducting to east-westward upwelling, formed the early Proterozoic sediments scattering in the south-north direction within the Platform.
