This book was released on 1973 with total page 834 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of modern paleomagnetic, radiometric, and biostratigraphic studies has provided an accurate geochronological framework for the past 10 million years--the Late Neogene. Marine zones based on calcareous and siliceous planktonic organisms are recognized from the sub-Arctic region to the sub-Antarctic and their correlation to the paleomagnetic time scale is now feasible in some detail for the past 5 my. Likewise, the relationship of geochemically calibrated mammalian biochronology to the marine succession has been greatly improved. Within this framework of time it is possible to delineate the history of major features in Late Neogene paleontology, climatology, and oceanography. (Author).

Book excerpt: Phosphatic concretions occur within diatomite in the upper part of the Miocene Monterey Formation near Lompoc, Calif. Absence of disruption of fine laminar bedding in the associated sediment by the concretions shows that they formed after complete compaction of the enclosing sediment.The concretions exhibit a strongly concentric color, chemical, and mineralogic zonation. Many of them are composed of a nucleus in which vivianite is the dominant mineral. Amorphous ferric phosphate, mitridatite, and francolite are the dominant phosphatic phases in successive layers toward the surface of the concretions. Cd and As contents increase tenfold from the nucleus outward, reaching a maximum of 2,000 ppm, whereas Ni content, with a maximum of 720 ppm, and Co content show the opposite trend. This mineralogy and elemental composition favor accretion under conditions of continuously increasing Eh and pH, during uplift into the fresh-ground-water zone of the terrestrial environment. Shale-normalized rare-earth-element patterns, however, suggest a marine source for the elements biogenic debris consisting of opal-A, organic matter, and carbonates of the enclosing sediment.
