Calcareous nannofossils, state of the art, Gulf of Mexico
The use of calcareous nannofossils to solve well correlation problems in beds of bathyal origin has become a pragmatic art. These microfossils are valuable to exploration because of their abundance in oceanic deposits and their present knowledge of their taxonomy and distribution in geologic time. The recognition of paleomagnetic events by their association with nannofossil events is also providing data for the calculation of depositional rates for subsurface stratigraphic intervals. Exploration companies are using the extinction horizons of numerous species of calcareous nannofossils, along with planktonic foraminifera, in the Neogene deposits of the northern Gulf of Mexico, to establish correlations between wells for which other correlation methods are tenuous.
