Book Description
The upper Cretaceous-Tertiary Nuussuaq Basin in West Greenland contains a many kilometres thick succession of siliciclastic sediments and overlying volcanic rocks. The first studies in the early 19th century were centred on the coal and fossils in the sediments and the minerals in the volcanic rocks, including famous occurrences of native iron. The present focus of interest includes modern stratigraphic and volcanological studies to decipher the basin evolution and support hydrocarbon and mineral exploration. This bulletin presents the lithostratigraphy, geology and geochemistry of teh Paleocene volcanic rocks of the Maligât Formation and its related intrusions on Disko and the Nuussuaq peninsula; it concludes with a detailed discussion of the effects of crustal contamination processes. The Maligât Formation is up to 2000 m thick and comprises four formally defined members and 15 chemically defined informal units. It is mainly composed of basalt lavas but also includes basaltic andesite, andesit and dacite flows and rhyolite tuffs. The silicic rocks and intrusions were produced by contaminiation in high-level magma chambers and commonly contain native iron. The comprehensive descriptions and analysis of each member and unit represent a synthesis of many years of work and are intended to serve as a guide for future studies, including exploration for mineral deposits associated with some units of the formation."--Back cover.

Book Description
Recently, recognition of the potential role of large igneous provinces in affecting ocean and atmosphere systems and biotic evolutionary pathways has lead to increased interest in this province. This has been further stimulated by the expansion in the search for oil and gas in Mesozoic and Tertiary sediments along the NE Atlantic Margin. An improved understanding of the interaction between igneous and sedimentary processes is vital for the identification of potential hydrocarbon resources.

Book Description
Petroleum Migration follows petroleum from its generation in source rocks through migration to the reservoir or the surface. The book is divided into 4 parts. Part 1 deals with both the generation of petroleum by the thermal breakdown of kerogen and the expulsion of the petroleum from the source rock. Part 2 considers secondary migration: the procesess which control petroleum behaviour during its movement through relatively permeable carrier beds from the mudrock sequences, which contain source intervals, to the reservoir in the structural culmination of the carrier bed or other trap. Part 3 contains case studies which show how understanding of generation, expulsion and secondary migration can be used to explain the distribution of oil and gas in a basin and therefore, to predict the nature of the petoleum in an undrilled prospect. Part 4 examines leakage from accumulations.

Book Description
A review of the extensive advances made in the understanding the petroleum geology of the Atlantic margin of northwest Europe, of the North Sea and of adjacent areas since the;ast conference in 1992. In particular, the volume focuses on: the development of and application of 3D seismic, time-lapse ('4D') and other innovative seismic tools; the ongoing refinement of sequence and other stratigraphic approaches, including the integration of detailed biostratigraphic data; the development of modelling at both the reservoir and basin scale which can respond to new data acquisition and be used to assess uncertainties at the reservoir scale and scenarios at the basin scale.

Book Description
The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks. Detailed knowledge of the diagenetic textures, fabrics, and minerals, and a prediction of the regional diagenetic response, partly controls hydrocarbon recovery programmes. In other words, knowledge of the diagenesis can aid (or even control) conservation policy. Similarly, facies and diagenetic trends w.ithin basins can influence exploration policy. This volume incorporates the majority of the principal contributions given to the NATO Advanced Study Institute held in the University of Reading, U.K., from July 12th-25th, 1981, at which the major themes of carbonate and terrigenous clastic sediments were treated sequentially from deposition to deep burial. Eighty selected scientists from twelve NATO and three other countries participated in the Institute. The keynote addresses which acted as the touchstones for discussion are presented here in the expectation that they will stimulate a still wider audience. We gratefully acknowledge the award of a grant from the Scientific Affairs Division of NATO to run the Institute, and also the cooperation of the University of Reading. Mrs. D. M. Powell helped in many ways with the organisation, and also retyped the entire manuscript of this book. A. Parker B. lv.

Book Description
This volume presents a suite of detailed stratigraphic and sedimentologic investigations of the Eocene Green River Formation of Wyoming, Colorado and Utah, one of the world’s foremost terrestrial archives of lacustrine and alluvial deposition during the warmest portion of the early Cenozoic. Its twelve chapters encompass the rich and varied record of lacustrine stratigraphy, sedimentology, geochronology, geochemistry and paleontology. Chapters 2-9 provide detailed member-scale synthesis of Green River Formation strata within the Greater Green River, Fossil, Piceance Creek and Uinta Basins, while its final two chapters address its enigmatic evaporite deposits and ichnofossils at broad, interbasinal scale.

Book Description
The basis of this investigation is the petrographic and geochemical understanding of principal igneous rock types of the Noril’sk region, in order to demonstrate that these data provide unique and self-evident solutions to the problems of petrogenesis and mineralization. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations. In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. Taking into account the vast number of publications on the petrology of Traps of the Noril’sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail. The second volume contains an atlas of Rock Indications of igneous rock-types; formally identified reference rocks from all igneous complexes of the region, as well as photographs of thin sections of typical rocks and analytical tables of rocks and minerals from the key sections of sedimentary units and intrusions. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section. Photomicrographs of the rocks in this book will be a useful aid in visualizing the diversity of rock types in the Traps; each photograph reflecting a unique combination of minerals.
