Marine phosphorites, the principal raw material for phosphatic fertilizers, do not occur uniformly through time and space. The origin of these unusual sedimentary rocks 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, one of the major and most recent phosphogenic periods throughout the geologic record. In addition, an oceanographic perspective is given by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This book is the third of four reference volumes which together cover the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the project's existence.

Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 7: Au, U, Fe, Mn, Hg, Sb, W, and P Deposits focuses on the characteristics, properties, origins, and structures of Au, U, Fe, Mn, Hg, Sb, W, and P deposits. The selection first elaborates on gold in the Proterozoic sediments of South Africa, nature of the Witwatersrand gold-uranium deposits, and origin of Western-States type uranium mineralization. Discussions focus on tectonic conditions, sedimentation, mineralization and alteration, architecture of the Witwatersrand Basin, source of wealth in the Witwatersrand Basin, gold mineralization in South Africa, and ground-rules for gold prospecting. The text then ponders on origin of the Precambrian banded iron-formations, aspects of the sedimentary petrology of cherty iron-formation, and genetic problems and environmental features of volcanosedimentary iron-ore deposits of the Lahn-Dill Type. Concerns cover geological setting, crystallization structures, origin of cherty iron-formations, similarities and differences between banded and oolitic iron-formations, regional geologic distribution, and general diagnostic statement. The manuscript examines sedimentary phosphate deposits, ancient manganese deposits, and freshwater ferromanganese deposits. The selection is a dependable reference for researchers wanting to explore Au, U, Fe, Mn, Hg, Sb, W, and P deposits.
