If you consider only the deposition process, some are almost instantaneous (a landslide or a mudflow for example). Some might even consider a volcanic ashfall as a sediment deposition. See this answer: earthscience.stackexchange.com/a/7895/18081 But if you consider the rock creation per se (i.e., compaction & consolidation), it requires diagenesis, a process which needs pressure (hence is invisible to us) and a lot of time (hence is not noticeable at human timescale). | |
