Salt tectonics is the study of how and why salt structures evolve and the three-dimensional forms that result. A fascinating branch of geology in itself, salt tectonics is also vitally important to the petroleum industry. Covering the entire scale from the microscopic to the continental, this textbook is an unrivalled consolidation of all topics related to salt tectonics: evaporite deposition and flow, salt structures, salt systems, and practical applications.
Coverage of the principles of salt tectonics is supported by more than 600 color illustrations, including 200 seismic images captured by state-of-the-art geophysical techniques, and tectonic models from the Applied Geodynamics Laboratory (The University of Texas). These combine to provide a cohesive and wide-ranging insight into this extremely visual subject.
This is the definitive practical handbook for professional geologists and geophysicists in the petroleum industry, an invaluable textbook for graduate students, and a reference textbook for researchers in various geoscience fields.

2021-07-07 01:36:37 “I went into geology because I like being outdoors, and because everybody in geology seemed, well, they all seemed like free spirits or renegades or something. You know, climbing mountains and hiking deserts and stuff.”

2021-07-04 20:36:36 The Geology student draws a perfect future in his head. Between the courses, the laboratory and the field courses, being a geologist seems to be the ideal job combining freedom, adventure, discovery and money. Unfortunately, the reality is very disappointing, especially in some countries of the world. We, who are writing these lines, have faced this harsh reality, but instead of giving up, as they say: "the obstacle is the way", we have given ourselves body and soul to build a better future for all geologists around the world.

We address all our dear geologists, whether you are students, graduates and job seekers, professionals or business owners, from now on you don't have to worry, GeologyHere, the new platform that unites the entire geology community and your new support is now launched.

GeologyHere , we are here to design your future

2021-06-30 10:53:49 USING GEOCHEMICAL DATA BY ROLLINSON, HUGH PEASE 2021 (FREE DOWNLOAD)

Overview

This textbook is a complete rewrite and expansion of Hugh Rollinson’s highly successful 1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and Pease’s new book covers the explosion in geochemical thinking over the past three decades, as new instruments and techniques have come online. It provides a comprehensive overview of how modern geochemical data are used in the understanding of geological and petrological processes. It covers major elements, trace elements, and radiogenic and stable isotope geochemistry. It explains the potential of many geochemical techniques, provides examples of their application, and emphasizes how to interpret the resulting data. Additional topics covered include the critical statistical analysis of geochemical data, current geochemical techniques, effective display of geochemical data, and the application of data in problem-solving and identifying petrogenetic processes within a geological context. It will be invaluable for all graduate students, researchers, and professionals using geochemical techniques.

Hugh Rollinson is an Emeritus Professor of Earth Sciences at the University of Derby. His particular interest is in the application of geochemistry to the early history of the Earth, and he has published on the geochemistry of Archaean rocks from Scotland, Sierra Leone, Zimbabwe, India, west Greenland, and Russia.

Victoria Pease is a Professor of Tectonics and Magmatism at Stockholm University. Her research focuses on unraveling Arctic tectonics. She sits on a number of international committees and is a chief editor of Precambrian Research.

Overview

You are sitting on a rock right now. it is a big rock, so big that you, your classroom, your school, your town, and everything else—zebras, apple trees, polar bears, sneakers—can sit on top of it. We call it the Earth, but it is really just a big rock surrounded by empty space.

This rock is important. On it sits every plot of land that will grow your food, every drop of oil that will power your cars, every person you will ever know. On this one rock, you will spend every moment of your life.

But how much do you know about this rock? Where did Earth come from, and how did it form? Has it always been just like this?

If you wanted to know how this rock, our home, came to be, what would you do? Where would you look for clues?

To begin, you might look down. Every small rock you see is a reflection of what Earth has gone through. Glassy black rocks mark moments when the Earth’s liquid insides spilled out onto its surface. Gritty, sandy rocks are the dead skin of the Earth, shed after years of wind and rain. Twisted, sparkly rocks formed deep in the bellies of mountains

2021-06-24 14:09:37 SEDIMENTOLOGY OF AQUEOUS SYSTEMS ( Free Download)

Overview

Studies of sediments have been increasingly highlighted internationally because of their negative influence on the quality of the aquatic environment. The problems caused by these sediments may be physical, whereby they can lead to the aggravation of water bodies and the subsequent obstruction of engineered structures, or they may be chemical upon the release f pollutants previously transported in association with them. To mitigate these impacts, sedimentological studies need to be structured carefully to meet specific needs. This volume, therefore, aims to explore sediments logically, from their origins, impacts on the aquatic environment to their collection in the field and subsequent analytical methodologies, in order to provide a thorough examination of one of the symptoms of anthropogenic impact on the environment

2021-06-23 03:23:14 FUNDAMENTALS OF GEOPHYSICS, SECOND EDITION
Overview
This second edition of Fundamentals of Geophysics has been completely revised and updated, and is the ideal geophysics textbook for undergraduate students of geoscience with only an introductory level of knowledge in physics and mathematics.

Presenting a comprehensive overview of the fundamental principles of each major branch of geophysics (gravity, seismology, geochronology, thermodynamics, geoelectricity, and geomagnetism), this text also considers geophysics within the wider context of plate tectonics, geodynamics, and planetary science. Basic principles are explained with the aid of numerous figures, and important geophysical results are illustrated with examples from the scientific literature. Step-by-step mathematical treatments are given where necessary, allowing students to easily follow the derivations. Text boxes highlight topics of interest for more advanced students.

Each chapter contains a short historical summary and ends with a reading list that directs students to a range of simpler, alternative, or more advanced, resources. This new edition also includes review questions to help evaluate the reader’s understanding of the topics covered and quantitative exercises at the end of each chapter. Solutions to the exercises are available to instructors.
