It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Whether one wants to explore ancient Maya ruins, zip through rainforest canopies, or search out the best surf breaks, this seventh edition is the key to adventure in Central America.

    He places us on the outcrops, rock hammer in hand, to examine the evidence for how these rough-hewn lands came to be. We see California and its gold assembled from pieces of old ocean floor and the relentless movements of the Earth’s tectonic plates. We witness the birth of the Rockies. And we investigate the violent earthquakes that continue to shape the region today. Into the West’s geologic story, Meldahl also weaves its human history. As we follow the adventures of John C. Frémont, Mark Twain, the Donner party, and other historic characters, we learn how geologic forces have shaped human experience in the past and how they direct the fate of the West today.

    Bangar is a book that is designed as a basic text for the students of B.Sc in Geology, B.E. in Civil Engineering and Mining Engineering, A.M.I.E. Section B, and also Diploma In Mining Engineering. This book can also be referred to by those who are appearing for the different competitive examinations conducted by the U.P.S.C. and other State PSCs. The book also provides the required information for the keen readers of Geology. Principles Of Engineering Geology covers topics such as physical geology, minerals, study of various crystals, and also the different types of rocks, such as igneous, sedimentary, and metamorphic rocks. The book also covers different geological structures and the Indian geology. Some of the other topics that are covered in the book are different deposits of ore and the role of engineering in geology. Various methods of exploration and surveying techniques are also covered in the book.K.M. Bangar is also the author of Engineering and General Geology.

    Titan Unveiled is one of the first general interest books to reveal the startling new discoveries that have been made since the arrival of the Cassini-Huygens mission to Saturn and Titan.Ralph Lorenz and Jacqueline Mitton take readers behind the scenes of this mission. Launched in 1997, Cassini entered orbit around Saturn in summer 2004. Its formidable payload included the Huygens probe, which successfully parachuted down through Titan's atmosphere in early 2005, all the while transmitting images and data--and scientists were startled by what they saw. One of those researchers was Lorenz, who gives an insider's account of the scientific community's first close encounter with an alien landscape of liquid methane seas and turbulent orange skies. Amid the challenges and frayed nerves, new discoveries are made, including methane monsoons, equatorial sand seas, and Titan's polar hood. Lorenz and Mitton describe Titan as a world strikingly like Earth and tell how Titan may hold clues to the origins of life on our own planet and possibly to its presence on others.Generously illustrated with many stunning images, Titan Unveiled is essential reading for anyone interested in space exploration, planetary science, or astronomy.-- "Lunar and Planetary Information Bulletin"

    From the most desolate desert to the depths of the jungle, from blistering heat and freezing cold to perpetual darkness and deadly UV, discover how a whole host of creatures have adapted to life in the most extreme conditions. And how they compete with one another to become the largest, the fastest, the most poisonous, or most devious - all in a bid to survive.Planet Earth II includes the first in-depth look at the urban environment, and the surprising range of behaviours occurring right under our noses, as well as some previously untouched island worlds. Filmed with remarkable 5k and infra-red technology, these are the challenges, the confrontations, and the triumphs of some of the most extraordinary creatures in the natural world, told from their perspective.This is our planet, as you have never seen it before.

    But through it all they persisted, motivated by the promise of a better life in which they could gather and worship God in their own ways. A collection of ragtag ships carried them across the ocean, among them The Mayflower. Crammed into the ship's hull, 102 people made this most famous pilgrimage. Besieged by illness and Indians and, many of them believed, witches, the Pilgrims eventually flourished, building up colonies and establishing their own rules for the practice of religion. Here is their dramatic story.

    John was a still sleepy island, this updated version provides a respite from busy Cruz Bay. The guide offers an insiders view into the quintessential St. John with its hiking trails, scrambles and gut walks. Singer, a long time island resident, provides a framework for reference with lots of fast facts and an easy to read description of places of interest, flora and fauna, amidst a well laid backdrop of St. John s rich history and island legend. --Virgin Voice, December 2006 January 2007

    Featuring many striking photos, this Very Short Introduction offers a fascinating portrait of the unique world of each planet as well as an illuminating discussion of moons, asteroids, and Trans-Neptunian objects. Leading planetary scientist David A. Rothery, who has chaired the European Space Agency's Mercury surface and composition working group since 2007, gives a stimulating overview of the origin, nature, and evolution of our Solar System, including the controversial issues of what qualifies as a planet, and what conditions are required for a planetary body to support life. He explains how the surfaces of planets and moons have been sculpted by geology, weather, and impacts by meteors and asteroids. Rothery shows how our knowledge has advanced over the centuries, and how it has expanded at a dramatic rate in recent years, going far beyond our Solar System to explore planets orbiting distant stars.

    Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.
