Phosphate Deposits of the World: Volume 3, Neogene to Modern Phosphorites
Author: P. J. CookPublisher: Cambridge University Press
ISBN: 9780521333702
Category : Science
Languages : en
Pages : 486
Book Description
The origin of marine phosphorites, the principal raw material for phosphatic fertilizers, appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene period, and investigations of modern oceanic environments where phosphorites are presently forming are also described.

Phosphorite Deposits from the Sea Floor Off Peru and Chile
Author: William C. BurnettPublisher:
ISBN:
Category : Marine sediments
Languages : en
Pages : 228
Book Description
Sedimentary phosphorites sampled from the sea floor off the coasts of Peru and Chile have been investigated to establish their ages and mode of formation. Results of uranium-series dating suggest that phosphate deposition was episodic rather than continuous during the late Pleistocene. Radiometric ages correlate well with periods of high eustatic stands of the sea. Bulk chemical and mineralogical compositions of the phosphate rocks were determined by instrumental techniques. Microanalysis, with an electron probe microanalyzer and a scanning electron microscope suggests that the apatite was authigenic and had formed as direct chemical precipitate rather than by replacement. A model of phosphorite formation is proposed which involves inorganic precipitation of apatite within anoxic pore waters and subsequent concentration of the apatite by physical processes. The concentration of apatite into indurated phosphate rocks is brought about by winnowing and reworking processes, possibly in response to a change in the sedimentary environment caused by eustatic sea-level fluctuations or tectonic movements.

Phanerozoic Phosphorite Depositional Systems
Author: Jörg TrappePublisher: Springer
ISBN: 3540696040
Category : Science
Languages : en
Pages : 409
Book Description
The book presents a new and comprehensive model for the development of phosphate sediments. Starting with geochemistry and including new methods in sedimentology (sequence stratigraphy), it results in an interdisciplinary approach to a resource system covering all fields of phosphate geology. For researchers, teachers and students alike the book offers a complete overview of the whole field including case studies of major deposits.
