geology How have global sedimentation rates changed

2021. 2. 4. Sedimentation rate presently varies many orders of magnitude depending on the place you observe. The rate of sedimentation is also different. Some places have continual sedimentation, others have episodic sedimentation events. That is why charts that show changes in sedimentation rate are usually done for individual sedimentary basins, to determine the basin evolution.
