Learning about rocks can give much pleasure to anyone interested in Earth and its development. I hope that readers of this book will share my enthusiasm for examining rocks with the microscope. I planned the book to be an introductory review of the main processes responsible for the microstructures of Earth rocks. However, I soon realized that if I did that, the book would be a collection of half-truths, with little scientific value. Though many rock microstructures are understood fairly well, the interpretation of many others involves considerable controversy, and new ideas are being published all the time. So, I have felt compelled to mention problems of interpretation and to present alternative views, where appropriate. Thus, the book has evolved into (1) a basic explanation of the main processes, (2) an introduction to more complex issues of interpretation and especially to the relevant literature, and (3) an outline of modern approaches and techniques, in order to emphasize the ongoing, dynamic nature of the study of rock microstructure. Because complicated problems cannot be discussed in detail in a book of this kind, I have tried to provide a sufficient number of references to enable the reader to delve more deeply. <...>

Volume 2 of the ‘Flotation Reagents Handbook’ is a continuation of Volume 1, and presents fundamental and practical knowledge on flotation of gold, platinum group minerals and the major oxide minerals, as well as rare earths.

Laboratory Manual in Physical Geology is produced under the auspices of the American Geosciences Institute (AGI) and the National Association of Geoscience Teachers (NAGT). For decades it has been the most widely adopted manual available for teaching laboratories in introductory geology and geoscience. This 11th edition is more user-friendly than ever, with an effective pedagogical format and many more teaching and learning options.

Geostatistics (also known as kriging) was developed for the mining industry during the 1960s and 1970s to estimate changes in ore grade. The principles of geostatistics are now applied to many applications that require statistically based interpolation techniques. Geostatistics provides a data value estimate for locations that cannot be sampled directly by examining data taken at locations that can be sampled.

Laboratory Manual in Physical Geology has been developed by the geoscience education community for the benefit of our students and is produced under the auspices of the American Geosciences Institute (AGI) and the National Association of Geoscience Teachers (NAGT). For decades and continuing through the present day, it has been the most widely adopted manual available for teaching laboratories in introductory geology and geoscience.

Решениями XIX съезда партии по пятому пятилетием,у плану развития народного хозяйства СССР предусматривается значительное увеличение выпуска черных и цветных металлов. Это связано с дальнейшим широким развитием техники обогащения РУД

В книге описываются открытые способы разработки россыпных месторождений. Основное внимание уделено вскрытию месторождений, системам разработки и условиям применения различных горных машин. Описываются также работы по оттаиванию мерзлоты и промывке песков
Книга предназначается в качестве учебника для учащихся горных учебных заведений, а также может служить практическим руководством для инженерно-технических работников горных предприятий.

Laboratory Manual in Physical Geology is the most widely adopted, user-friendly manual available for teaching laboratories in introductory geology and geoscience. The manual has been produced under the auspices of the American Geological Institute (AGI) and the National Association of Geoscience Teachers (NAGT). It is backed up by a premium web site at www.mygeoscienceplace.com, GeoTools (ruler, protractor, UTM grids, sediment grain size scale, etc.), an Instructor Resource Guide, and resources on the Instructor Resource Center (IRC) on DVD. The idea for this jointly sponsored laboratory

manual was proffered by Robert W. Ridky (past president of NAGT and a member of the AGI Education Advisory Committee), who envisioned a manual made up of the “best laboratory investigations written by geology teachers.” To that end, this product is the 25-year evolution of the cumulative ideas of more than 200 contributing authors, faculty peer reviewers, and students and faculty who have used past editions. <...>

В первом издании «Практического пособия для коллекторов» автор стремился познакомить средний технический персонал геологической службы с основными геологическими понятиями и дать рекомендации, как работать в поле. Судя по тому, что тираж книги разошелся в течение трех месяцев, можно думать, что пособие соответствовало своему назначению.
