Rare and violent events through geological time are the theme of this readable and thought-provoking view of the Earth’s history. The evidence for such episodes and rare ‘catastrophic’ happenings has been gleaned from the geological record of the author’s travels all over the world. Such events are shown to dominate the gradual and continuous processes that we see in the record of the history of the Earth. From hurricanes to episodic evolution, from colliding continents to asteroid impacts - the importance of these events is presented with many illustrations, both pictorial and anecdotal. Jargon-free and entertaining, the ideas presented in this book will stimulate the student, provoke the professional and provide an enjoyable read for all.
