本文认为，大洋岩石圈拆沉和大陆下地壳拆沉是不一样的：(1)拆沉的物质不同。

The author thinks that the ocean lithosphere delamination (OLD) is different from the continental lower crustal delamination (CLCD) in the paper: (1) the different delamination material.

而下地壳拆沉是由于下地壳加厚使下地壳密度增加引起的，还要求其下刚性的岩石圈地幔转变成塑性的软流圈地幔才有可能发生。

And CLCD is caused by the crust thickening to increase the crust "s density, and require the underlying lithosphere mantle to change from rigidity into plasticity."
