PELAGIC SEDIMENT, DEEP WATER CHEMISTRY, AND TECTONICS: AN APPLICATION OF THE HISTORY OF BIOLOGICAL SEDIMENT ACCUMULATION ON THE TECTONIC HISTORY OF THE CARIBBEAN

The distribution of biogenic silica in pelagic sediment enables us to demonstrate that the Cen­tral American isthmus shoaled from 35 to 15 MA, gradually stopping the transfer of dissolved silica in interme­diate ocean water into the Caribbean. Between 15 and 4.2 MA it continued to shoal, but during...
