The ocean floor rock, basalt, along with the sediment that built up on top of it, was drawn down at the edge of an ocean as part of the conveyor-belt mechanism that moves the continents.

海洋板块的岩石，玄武岩，以及覆盖其表面的沉积物被拉沉到海洋底部，充当移动大陆的传送带机制的一部分。

The basalt and the CO2 would react with each other, reducing the scope for leaks, which would be further diminished by the blanket of sediment that covers the ocean floor in that area.

这些玄武岩还会与二氧化碳发生化学反应，从而减少二氧化碳的泄漏。由于在这个海床上覆盖着一层沉淀物，二氧化碳的泄漏便又得到了进一步的减少。
