Download or read book Cooccurrence of Fe Fe Ca and Ca phosphate Minerals in Concretions Within the Monterey Formation written by David Z. Piper and published by . This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Siliceous Phosphatic and Clauconitic Sediments of the Tertiary and Mesozoic written by Akihito Iijima and published by VSP. This book was released on 1994-04 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Proceedings volume contains 14 papers from the symposium ''Siliceous, Phosphatic and Glauconitic Sediments of the Tertiary and Mesozoic'', which was held during the 29th International Geological Congress, Kyoto, Japan, 24 August--3 September, 1992. The first part of this volume consists of papers dealing with Tertiary biosiliceous sediments of the Pacific Rim, starting in the northwest. The second part of the volume is composed of papers dealing with Tertiary and Mesozoic phosphatic rocks and phosphatebearing sequences, in particular of the eastern Pacific Rim and the Middle East. The articles serve to emphasize the similarities and differences between the Pacific Neogene successions and the Tethyan Mesozoic sequences of the Middle East.
