Deep-sea carbonate and the deglaciation preservation spike in pteropods and foraminifera
The aragonite compensation depth fluctuated considerably during the last 20,000 yr. This fluctuation culminated in a preservation spike at about 14,000 yr BP . The aragonite preservation stratigraphy parallels that in calcitic foraminifera, and constitutes part of a worldwide phenomenon signalling c...

. The aragonite preservation stratigraphy parallels that in calcitic foraminifera, and constitutes part of a worldwide phenomenon signalling considerable changes in ocean chemistry and providing a useful tool for correlation. |
