Six million years ago, a vast ocean--which scientists have named Tethys--vanished from the face of the earth. Vanished Ocean tells the fascinating story of Tethys, offering an illuminating account of the scientific evidence for the ocean's existence. World-renowned geologist and oceanographer Dorrik Stow describes the powerful forces that shaped the ocean; the marine life it once held and the rich deposits of oil that life left behind; and the impact of its currents on environment and climate. The story of Tethys is also a story of extraordinary episodes such as the virtual drying up of the...

Ideas and concepts in sedimentology are changing rapidly but fundamental field work and data collection remain the basis of the science. This book is intended as a guide to the recognition and description of sedimentary rocks in the field. It aims to help the geologist know what to observe and record and how best to interpret this data.

The emphasis is on illustrating the principal types of sedimentary rocks and the book contains over 400 superb colour photos and drawings. The introductory chapter defines the main types of sedimentary rock and their initial recognition, followed...

The importance of the oceans to life on Earth cannot be overstated. Liquid water covers more than 70% of our planet's surface and, in past geological time, has spread over 85%. Life on Earth began in the oceans over 3.5 billion years ago and remained there for the great majority of that time. Today the seas still provide 99% of habitable living space, the largest repository of biomass, and holds the greatest number of undiscovered species on the planet. Our oceans are vital for the regulation of climate, and with global warming and decreasing land area, they have become increasingly important...
