The most important postmortem processes include transport, test size sorting, mechanical breakage and erosion, test dissolution and so on. The author put forward two new concepts: foraminiferal test"breakage index" and"dissolution index" to quantitatively describe the postmortem processes, and applied them to the observation and experiment on test breakage and dissolution.
