The alkaline igneous rocks and carbonatites are compositionally and mineralogically the most diverse of all igneous rocks and, apart from their scientific interest, are of major, and growing, economic importance. They are important repositories of certain metals and commodities, indeed the only significant sources of some of them, and include Nb, the rare earths, Cu, V, diamond, phosphate, vermiculite, bauxite, raw materials for the manufacture of ceramics, and potentially Th and U. The economic potential of these rocks is now widely appreciated, particularly since the commencement of the mining of the Palabora carbonatite for copper and a host of valuable by-products. Similarly, the crucial economic dominance of rare earth production from carbonatite-related occurrences in China, has stimulated the world-wide hunt for similar deposits. This volume describes and provides ready access to the literature for all known occurrences of alkaline igneous rocks and carbonatites of Antarctica, Asia and Europe excluding the former USSR, Australasia and oceanic islands. More than 1,200 occurrences from 59 countries are outlined together with those of 57 oceanic islands and island groups. The descriptions include geographical coordinates and information on general geology, rock types, petrography, mineralogy, age and economic aspects with the principal references cited. There are 429 geological and distribution maps and a locality index. As has been demonstrated by the three earlier volumes, the present book is likely to be of considerable interest to mineral exploration companies, as there are no comprehensive published reviews of the economic aspects of the alkaline rocks. It will also interest research scientists in the fields of igneous petrology and volcanology, and geologists concerned with the regional distribution of igneous rocks and their geodynamic relationships.
Research into the reproductive biology of crop plants has expanded greatly in recent years and has lead to an increasing awareness of the importance of flowering, pollination, and fruit set in crop productivity. This book focuses specifically on tree cultivation. It deals with the basic biology of sexual reproduction and relates this to the practical aspects of tree crop breeding and orchard management for fruit and seed production, in both temperate and tropical species.It is aimed at both students and research scientists in horticulture, forestry, and pollination ecology as well as those working in tree breeding, tree cultivation, and orchard management. The conservation problems of rainforest regeneration in the tropics and subtropics and of changing land use priorities in Europe and North America also make this book of value to those concerned with tree species preservation and survival.
This extract from the Eerdmans Commentary on the Bible provides Diamond and Clines' introduction to and concise commentary on Jeremiah and Lamentations. The Eerdmans Commentary on the Bible presents, in nontechnical language, the best of modern scholarship on each book of the Bible, including the Apocrypha. Reader-friendly commentary complements succinct summaries of each section of the text and will be valuable to scholars, students, and general readers. Rather than attempt a verse-by-verse analysis, these volumes work from larger sense units, highlighting the place of each passage within the overarching biblical story. Commentators focus on the genre of each text—parable, prophetic oracle, legal code, and so on—interpreting within the historical and literary context. The volumes also address major issues within each biblical book—including the range of possible interpretations—and refer readers to the best resources for further discussions.
The Babylonian Gilgamesh epic is the oldest long poem in the world, with a history going back four thousand years. It tells the fascinating and moving story of Gilgamesh's heroic deeds and lonely quest for immortality. This book collects for the first time all the known sources in the original cuneiform, including many fragments never published before. The author's personal study of every available fragment has produced a definitive edition and translation, complete with comprehensive introductory chapters that place the poem and its hero in context."--Publisher's description.
