Foraminifers dissolution

Anderson D. M. and Archer D. (2002) Glacial-interglacial stability of ocean pH inferred from foraminifer dissolution rates. Nature 416(6876), 70—73. 

A variety of processes may affect a foraminifer test as it falls through the water column or is buried in sea-floor sediment. These processes can loosely be divided into dissolution, overgrowth and recrystallization, although the processes are inter-related. Parts of the test may be more susceptible to dissolution and recrystallization than others.
