By B.U. Haq, A. Boersma

This fantastically illustrated textual content booklet, with state of the art illustrations, turns out to be useful not just for an advent to the topic, but additionally for the appliance of marine microfossils in paleoceanographic, paleoenvironmental and biostratigraphic analyses. the new revival of curiosity in marine micropaleontology around the globe within the wake of the improvement of series stratigraphic versions has resulted in the choice to reissue the amount in its unique, yet paperback, shape. the tips expressed in numerous chapters of this moment version stay as legitimate this day as they have been whilst the ebook was once first issued. The textual content, besides the fact that, comprises an up to date Phanerozoic geologic time which has been significantly converted because the Nineteen Eighties.

In more complex agglutinated genera an outer smooth microgranular wall may cover a complex inner layer. This inner wall appears spongy and where portions of the inner wall are folded inward into the chamber of the test, the result is an intricate subdivision of the chamber interior. This type of wall structure has been termed labyrinthic (alveolar) in the agglutinated foraminifera (Cyclammina, Fig. 6D). Microgranular walls Microgranular walls evolved during the Paleozoic and are considered the link between the agglutinated and the precipitated tests in foraminifera.

Alkalinity Alkalinity is an expression of the capacity of sea water to dissolve calcium carbonate. As a function of the concentration of CO2 in the water, alkalinity is governed chiefly by temperature, pressure, and biological respiration. The top 500 m of sea water are said to be saturated with respect to calcium carbonate which reflects the high alkalinity in this region. It also means that both Ca and COs^" are available and can readily be precipitated. Below 500 m water is considered undersaturated with respect to calcium carbonate and thus carbonate may begin to go into solution.
