摘要

华北板块的重力异常和地质构造特征与华南板块又有明显的差异,我们分别对其布格重力异常与地壳厚度的关系进行了统计分析.发现两者的相关系数、回归系数、以及由此推算出的壳幔密度差都有较大的差别。这些差别反映了华北与华南在地壳和上地幔结构上的不同,并与华北、华南两大板块不同的构造经历相联系。

Abstract：

The North China plate is obviously different from the South China plate in Gravity anomaly and geological-tectonic characteristics. Statistic analysis of the correlation between Bouguer gravity anomaly and crustal thickness has been made for these two plates respectively, and it is found that they are remarkably different in correlation coefficient, regression coefficient and the calculated density difference between the crust and the mantle. These diffe rences suggest that North China and South China have different ciustal and upper mantle textures, which must have had to do with the different tectonic evolutions of these two great plates.
