The geologic sciences continue to undergo remarkable changes. Those changes that have endured over time have been incorporated into each edition of this manual since the first edition was published in 1951. Although the subject matter has changed and expanded in scope, the number of laboratory sessions in a given academic quarter or semester has not increased. Because the time available in a quarter or semester cannot be expanded without disrupting the class schedule for the entire college or university, the problem of too much material for too little time poses a dilemma for authors, instructors, and students. <...>
This volume is dedicated to Kenneth Jingwah Hsfi, Professor emeritus of the Swiss Federal Institute of Technology (ETH-Zfirich). It collects the proceedings of the Symposium on "Paradoxes in Modern Geology", held in Beijing on the 13th and 14th September 1999, to honour his 70th birthday.
Physical geology is the study of the earth's rocks, minerals, an dsoils and how they have formed through time. Complex internal processes such as plate tectonics and mountain-building have formed these rocks and brought them to the earth's surface . Earthquakes are the result of the sudden movement of crustal plates, releasing internal energy that becomes destructive at the surface. Internal heat and energy are released also through volcanic eruptions. External processes such as glaciation, running water, weathering, and erosion have formed the landscapes we see today. <...>
Изложены основные проблемы геологии, гидрогеологии и инженерной геологии. Даны характеристика и классификация геологических карт и разрезов. Приведены сведения о происхождении и формировании подземных вод, закономерностях движения и взаимодействия нх с вмещающими горными породами. Рассмотрены гидрогеологические и инженерно-геологические исследования применительно к строительству и эксплуатации инженерных гидромелиоративных систем и гидротехнических сооружений. Второе издание (1-е изд.— 1976) переработано и дополнено в соответствии с новой программой обучения и с учетом последних достижений науки и практики. Для студентов вузов, обучающихся по специальности «Гидромелиорация».
В книге излагаются современные сведения о всех 4.6 млрд лет истории Земли — о росте ядра и эволюции ее оболочек, происхождении и эволюции атмосферы и гидросферы, образовании и эволюции океанической и континентальной земной коры, геологических периодах последних 600 млн лет истории Земли. Специальные главы посвящены истории жизни на Земле, палеомагнитным данным об обращениях полярности земного магнитного поля, данным об образовании и распаде суперконтинентов и движении континентов и полюсов и, наконец, истории климата, включая ледниковые периоды
Imagine walking on a rocky shore.You can see the pounding surf, hear stones clink together as waves recede, feel the wind blowing in your hair. But the cliffs don’t move and the ground doesn’t shake. Even though the Earth appears to be a firm foundation beneath your feet, it is a dynamic planet. Continents slowly shift position;mountains rise and then erode away.These motions escape casual observation because they are generally slow, although every year events such as volcanic eruptions and earthquakes remind us that geologic change can be rapid. <...>
This book concerns the nature, origin, evolution and signifi cance of Earth materials. Earth is composed of a variety of naturally occurring and synthetic materials whose composition can be expressed in many ways. Solid Earth materials are described by their chemical, mineral and rock composition. Atoms combine to form minerals and minerals combine to form rocks. Discussion of the relationships between atoms, minerals and rocks is fundamental to an understanding of Earth materials and their behavior.
The term mineral is used in a number of ways. For example, elements on your typical breakfast cereal box are listed as minerals. Oil and gas are considered mineral resources. All these are loose interpretations of the term mineral. <...>
Earth and mind: These are the substance and essence of our work as geoscientists. Earth is the focus of our work—understanding its systems and sensitivities. Mind is the most important asset we bring to this work. Geoscientists learn a body of knowledge that frames their thinking, a battery of methods that they can use to address a problem, and a sophisticated set of skills for collecting and analyzing data. But perhaps most important, geoscientists have a way of thinking about Earth that grows from a combination of their training, their scientific work, and their world experiences. While each individual is unique, geoscientists share a common core of interests, approaches, skills and knowledge that constitute geoscience expertise. This volume explores the nature of that expertise. <...>
The geological (endogenic and exogenic) processes operating in interior and exterior domains of earth are bringing dynamic changes in the lithospheric and geomorphic terrains of this planet since its origin. The interplay of magmatic, tectonometamorphic and metallogenic processes is continuously evolving new continental and oceanic plates (blocks) enriched with magmatic plume and economic minerals. The diverging and converging margins of these blocks were stressed and formed orogenic mobile belts and mountains.
