Problems of current interest relating to the earth's physical history will be discussed in this volume. Each chapter constitutes a subject in itself, but the sequence I have chosen will, I hope, show and explain the deeper correlation of several terrestrial pro cesses which, at first sight, appear to be heterogeneous. The geologist follows the changing face of the earth, the oscillations of the sea-level, the pulsation of folding and mountain-building, the periodicity of the ice-ages, the rhythmical cadence of Life. Just as the physician will draw his conclttsions from outward symptoms when examining his patient, so the geologist tries to discover the deeper significance of the sequence of observed phenomena by ieeling the pulse of the earth. The many additions and revisions which have had to be made in this second. edition include three new chapters, several new sections in other chapters, I09 new textfigures, I2 tables and 2 plates. A leu) fundamental geological terms have been explained in Chapter I.

In The Pulse of the Earth Adam Bobbette tells the story of how modern theories of the earth emerged from the slopes of Indonesia’s volcanoes. Beginning in the late nineteenth century, scientists became concerned with protecting the colonial plantation economy from the unpredictable bursts and shudders of volcanoes. Bobbette follows Javanese knowledge traditions, colonial geologists, volcanologists, mystics, Theosophists, orientalists, and revolutionaries to show how the earth sciences originate from a fusion of Western and non-Western cosmology, theology, anthropology, and geology. Drawing on archival research, interviews, and fieldwork at Javanese volcanoes and in scientific observatories, he explores how Indonesian Islam shaped the theory of plate tectonics, how Dutch colonial volcanologists learned to see the earth in new ways from Javanese spiritual traditions, and how new scientific technologies radically recast notions of the human body, distance, and the earth. In this way, Bobbette decenters the significance of Western scientists to expand our understanding of the evolution of planetary thought and rethinks the politics of geological knowledge.

The Earth Hums in B Flat is a story of dark family secrets unraveled by the shrewd insight of twelve-year-old Gwenni Morgan, a child with an irrepressible spirit living in a Welsh village that is reluctantly entering the modern age. From the small bed that she shares with her sister at night she flies up into the starry sky above her village and looks down on the lives of its inhabitants. And when the family that she babysits for is rocked by the sudden, unexplainable disappearance of their patriarch, Gwenni is determined to solve the mystery of Ifan EvanÕs whereabouts. Turning amateur detective, she is unaware that the trail will lead her closer to home than she ever imagined. Told with a breathtaking, irresistible blend of freshness and wisdom, the voice that sixty-two-year-old Welsh debut novelist Mari Strachan has created with Gwenni is vibrant, charming, and full of heart. An unforgettable character, GwenniÕs unique way of seeing the world lends her the ability to make the ordinary extraordinary. A magical novel about the trials of youth, familial duty, and understanding, The Earth Hums in B Flat will transport you to another time and place.Ê

In "Earth Under Fire, " Paul LaViolette investigates the connection between ancient world catastrophe myths and modern scientific evidence of a galactic destruction cycle, demonstrating how past civilizations accurately recorded the causes of these cataclysmic events, knowledge of which may be crucial for the human race to survive the next catastrophic superwave cycle.

The Earth's Age and Geochronology provides an outline of geochronological methods, applications, and interpretations. This book discusses the fossil fission track method of dating. Organized into 12 chapters, this book begins with an overview of an accurate chronometer for measuring time intervals that must contain some sort of mechanism in which it operates at a predictable or known rate. This text then discusses the methodology of dating as well as the importance of long cooling histories. Other chapters consider the application of the experimental method to idealized, undisturbed systems. This book discusses as well the concept that in plutonic environments daughter isotope retention may often not commence until long after crystallization, or the peak of metamorphism. The final chapter deals with the applications of geochronology wherein the effects of selectivity will be particularly evident. This book is a valuable resource for nuclear physicists, astronomers, geologists, cosmologists, geochronologists, experimentalists, and scientists.
