Book Description
Sequence stratigraphy has advanced considerably since the early applications of the concepts on seismic data. It attempts to discern the migration of facies re sulting from changes in a combination of factors such as, sea level, tectonics, climate and sediment flux, and integrates it with a meaningful chronostratigraphy. The stratigraphic record is envisioned as a framework of repetitive packages of genetically-related strata, formed in response to the shifting base level, in which the locus of deposition of various sediment types may be anticipated. This attribute is rapidly promoting sequence stratigraphy as an indispensable tool for prediction of facies in exploration and production geology. In hydrocarbon exploration the application of sequence stratigraphy has ranged from anticipating reservoir- and source-rock distribution to predicting carbonate diagenesis, porosity and permeability. The capability to anticipate vertical and lateral distribution of facies and reservoir sands in the basinal, shoreface, incised valley-fill and regressive settings alone has been a great asset for exploration. In frontier areas, where data are often limited to seismic lines, sequence-stratigraphic methodology has helped determine the timing and of types of unconformities and anticipate transgressive- and regressive-prone intervals. In production it is aiding in field development by providing improved source and seal predictions for secondary oil recovery. A recognition of stratigraphic causes of poor recovery through improved understanding of internal stratal architecture can lead to new well recompletions and enhanced exploitation in existing fields. The sequence-stratigraphic discipline is in a state of rapid expansion.

Book Description
This book provides a comprehensive and critical summary of clay mineral literature that relates to geology and geologic processes, making it useful both as a reference book for geologists and as a text for the specialist.The book encompasses the full scope of clay-shale geology. An introductory chapter provides basic background terminology and classification. This is followed by a relatively long chapter on the structure and composition of the various clay minerals. Chapter 3 provides an introduction to soil formation, chemical weathering, microbial alteration and the pedogenic formation of clay minerals. Chapters 4 and 5 cover the continental and marine transport, and deposition of clays. Both mechanisms and examples are presented, ranging from biodepositional to the nepheloid layer. Chapter 6 reviews data on the low to high temperature formation of clay minerals from marine volcanics, and the growth of authigenic clays in shallow marine, brackish, and evaporite environments. Chapter 7, Diagenesis Metamorphism, covers both burial diagenesis and the processes occurring during the conversion of shale to clay. Chapter 8 discusses the formation of authigenic-diagenetic formation of clays in sandstones. Chapter 9 describes the temperal distribution of clay minerals in North and South America, Europe, Africa and the Atlantic Ocean. The clay suites are related to factors such as continental drift, tectonics, climate and environment. The final brief chapter covers compaction, lithification and some general features of shales.The book is liberally sprinkled with x-ray patterns, chemical analyses, and SEM and TEM pictures, in addition to hundreds of examples.

Book Description
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.
