"This bulletin presents the lithostratigraphy of the Cretaceous-Paleocene sedimentary succession of the Nuussuaq Basin. The Nuussuaq Group (new) overlies Precambrian basement rocks and is overlain by volcanic rocks of the West Greenland Basalt Group. The Nuussuaq Group comprises ten formations, five of which are erected herein whilst the remainder are redefined or revised in accordance with modern practice. Six of these formations are further divided into members (a total of eighteen, of which fifteen are new) and two beds are formally erected."--Publisher's website.

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.

The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.
