什么是 Subsidence curve?

Definition 16.2 University Earth and Space Sciences — Year 2 · 第 16 章 — Sedimentary Basins Compared

The total subsidence curve uses the sediment thickness as it was at each time, plus the water depth; the tectonic subsidence curve replaces the sediment by water and removes its isostatic effect.
