Böcker av Graham Park

Graham Park tracks the many changes that the Earth has experienced from its initial formation about 4,500 million years ago to the present day, with a glance into its future.

The first 2,500 million years of the geological history of Britain are stored in the gneisses of the Lewisian Complex of NW Scotland. Graham Park explores the long journey of discovery in which this history was gradually deciphered and the controversies and arguments in the scientific community over the past two centuries that arose in this period.

Introducing Tectonics, Rock Structures and Mountain Belts is written to explain the key concepts of tectonics and rock structures to students and to the interested non-specialist, especially those without a strong mathematical background. The study and understanding of geological structures has traditionally been guided by the rigorous application of mathematics and physics but, in this book, Graham Park has avoided mathematical equations altogether and has reduced the geometry to the minimum necessary. The application of plate tectonic theory has revolutionised structural geology by giving the study of rock structures a context in which they can be explained. Since the large-scale movements of the plates ultimately control smaller-scale structures, the study of tectonics is the key to understanding the latter. The reader is thus introduced to large-scale Earth structure and the theory of plate tectonics before dealing with geological structures such as faults and folds. Studies by structural geologists of the movement history of rock masses relative to each other, as revealed by the study of fault systems and shear zones, has helped to integrate rock structures with plate tectonics and this has been emphasised in the book. One of the most exciting aspects of geology is the study of the great mountain ranges, orogenic belts. The final three chapters of the book explain how knowledge of plate tectonic theory, geological structures and the processes of deformation may be employed to understand these orogenic belts. hilst excessive use of terminology is avoided, all technical terms are in a Glossary and, as with all books in this series, the text is illustrated profusely.

Our world is made of rock. Although much of the Earths surface is covered by vegetation, concrete or water, if one digs down far enough solid rock will always be found. Those who live in a landscape where rock outcrops are obvious will have wondered about the kind of rocks they are looking at and how they came to be where they are now. This introductory book explains in simple terms what geology can tell us about the world. Many objects of great beauty and which excite our curiosity, such as crystals or fossils, are to be found by examining rocks. Those searching for and examining such objects gain much more by knowing how and when they originated. In particular fossils, whilst interesting in themselves, tell us from their context in geological time of biological evolution and these clues give an insight into the origins of life on earth. Copiously illustrated this book is intended for those whose interest in geology has been awakened, perhaps by media coverage of earthquakes or dinosaurs and want to know more. Technical terms are kept to a minimum and are explained in a glossary.

An explanation of how and why mountains are formed. The age, location, life cycle and key features of different mountain types are described.

Over the many millennia that the human race has inhabited our planet, a use has been found for almost everything that is to be found on it. However, since the Industrial Revolution, many of the resources that we have come to rely on are being depleted, some at an alarming rate. Misuse of others, such as fossil fuels, is causing such damage to the environment that measures are being taken at an international level to restrict their useIntroducing Natural Resources explains how the natural resources of the Earth originated, by outlining the astronomical and geological evolution of the planet in the early period of its existence. The genesis, mode of occurrence, and abundance of the various non-renewable mineral resources are described, together with the methods of extraction, extent of reserves, and any environmental problems. The use of renewable resources, such as solar energy, air, and water, are then discussed, together with plant and animal life, which are renewable resources only if properly managed. The book concludes with a summary of future issues in resource management.Copiously illustrated, this book is intended for those whose interest in natural resources has been stimulated, perhaps by media coverage of declining resources or environmental pollution, and who want to better understand the issues involved. Technical terms are kept to a minimum and are explained in a glossary.
