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...

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.
