-
5·In contrast, the less abundant HT and LT2 basalts may imply a weakening of the influence of the mantle plume activity.相反，厚度较小的HT和LT2玄武岩则可能是意味着地幔柱活动影响的减弱。
-
6·The theory of plate tectonics is the mainstream of tectonic in the present, and mantle plume tectonics is the important supplement for it.板块构造理论是当今大地构造学的主流，地幔柱构造则是对它的重要补充。
-
