The present volume is an intellectual agglomeration covering a variety of topics in diagenesis. It starts with the diagenesis of marine pore waters and soft-sediment deformations, followed by two chapters on sandstones - one on climatic influence in terrestrial sandstone diagenesis and the other on the deep-sea volcaniclastic sandstones. Diagenesis of carbonates is treated next, with one chapter on compactional diagenesis and another devoted to a case study (Aymestry Limestone Beds, UK). There are two chapters on the origin and migration of oil: (a) maturation of organic matter, and (b) relation of diagenesis to mineralization and hydrocarbon reservoir development, followed by a chapter on sedimentary ore genesis - banded iron-formation. In conclusion there are two chapters on paleosols. This book will be of interest to geologists, geochemists and petroleum engineers.

In recent years, several major natural and man-made hazards have challenged scientists, government officials and the public in general: earthquakes, major volcanic and other seismic eruptions in Mount St. Helens, EI Chichon, Mexico city, Nevado del Ruiz, Japan, Italy, Greece, Cameroon and many other places on our globe; Tsunami in the Pacific Ocean and deadly storm surges along the coasts of India, Bangladesh and Japan; Cyclones, floods, thunderstorms, snow storms, tornadoes, drought, desertification and other climatic catastrophes; Amoco-Cadiz oil spill accident (France), Three-Mile Island (U. S. A. ) and Chernobyl (U. S. S. R. ) nuclear accidents, Bhopal chemical accident (India), acid rain (Canada, U. S. A. ) and other technological disasters. Such hazards have snuffed out millions of lives, infli

Forty-four contributions survey the established and experimental means of dating Quaternary Period surficial materials. The basic theory, procedures, and accuracy are reviewed for sidereal, isotopic, radiogenic, chemical and biological, geomorphological, and correlation methods. A series of case studies then illustrates the application of geochronology in Quaternary geology and the emerging field of paleoseismology. The volume is a minor revision and update of a portion of a 1998 report to the U.S. Nuclear Regulatory Commission. Member price, $56. Annotation copyrighted by Book News, Inc., Portland, OR.
