Petrophysics, beginning with Archie’s historical yet evergreen equations, has a key function in all applications of geosciences, petroleum engineering and related technologies. It helps us to understand the processes and controlling properties and creates relationships between parameters we can measure as output of the dramatic progress in exploration techniques and properties we need for reservoir characterization (hydrocarbons, water, minerals, geothermal energy), exploration of natural resources, geotechnical constructions and environmental protection.

С.И. Пахомов всю свою жизнь посвятил работе в инженерной геологии, грунтоведении и гидрогеологии. Более 50 лет он проработал в Производственном и НИИ изысканий в строительстве (ПНИИИС), в Северо-Кавказском филиале которого прошёл путь от младшего научного сотрудника до директора.

Isotope geochemistry has grown over the last 60 years to become one of the most important fields in the earth sciences. It has two broad subdivisions, namely, radiogenic isotope geochemistry and stable isotope geochemistry. These subdivisions reflect the two primary reasons why the relative abundances of isotopes of elements vary in nature, which are radioactive decay and chemical fractionation; in this context, “fractionation” is any process in which the isotopes of the same element behave differently.

Рассмотрены основные закономерности набухания глинистых грунтов, в том числе при замачивании их агрессивными растворами. Обобщен опыт проектирования, строительства и эксплуатации сооружений на таких грунтах. Освещены вопросы устройства оснований и фундаментов на набухающих грунтах. Настоящее издание переработано и дополнено в соответствии с новыми техническими решениями и нормативными документами. Изд. 1-е вышло в 1974 г.
Для инженерно-технических и научных работников проектных, строительных и научно-исследовательских организаций, а также служб эксплуатации.

There have been two dominant models used in describing the chemical and electronic behavior of a surface. One is the atomistic model, or the “surface molecule” model; the other is the band model, often called for emphasis the “rigid band” model. The atomistic model has been preferred in general in discussions of the chemical processes at a solid surface; the rigid band model is often preferred in discussions of electron exchange between the solid (especially a semiconductor) and a surface group, where, for example, the conductivity of the solid is changed.

This volume of the Geology of the Philippines, Second Edition comes at an opportune time when the Philippines has become once more  a beehive of activities by geologists owing to the efforts of government to promote the revitalization of the mining industry. This edition is a timely reference material that gives the reader an overview of the geology of the Philippines, as well as the stratigraphic make-up of local areas.

The engineering geologist should be able to identify soil and rocks by visual examination and to interpret the geological history and structure of a site as set out in Chapter 4. He needs to be able to describe these rocks and soils both geologically and, in an unambiguous way, in terms of their relative strengths. He also must have knowledge of geomorphological processes, be able to interpret terrain features and hydrogeological conditions. Principles of hydrogeology are dealt with in Chapter 5.

As the Nation's principal conservation agency, the Department of the Interior has responsibility for most of our nationally owned public lands and natural resources. This includes fostering the sound use of our land and water resources; protecting our fish, wildlife, and biological diversity; preserving the environmental and cultural values of our national parks and historical places; and providing for the enjoyment of life through outdoor recreation. The Department assesses our energy and mineral resources and works to assure that their development is in the best interests of all our people by encouraging stewardship and citizen participation in their care. The Department also has a major responsibility for American Indian reservation communities and for people who live in island territories under U.S. administration. <...>

Пособие открывает серию книг – обзор химических элементов по группам периодического закона Д.И.Менделеева. В книге подробно освещается педагогическое, научное и философское значение закона и системы Д.И.Менделеева

The origin of granite has for long fascinated geologists though serious debate on the topic may be said to date from a famous meeting of the Geological Society of France in 1847. My own introduction to the subject began exactly one hundred years later when, in an interview with Professor H.H. Read, I entered his study as an amateur fossil collector and left it as a committed granite petrologist - after just ten minutes!
