Книга содержит основы грунтоведения и механики грунтов и подробное изложение практики их применения к проектированию оснований и земляных сооружений.
Книга рассчитана на широкие круги инженеров-строителей и проектировщиков, а также на специалистов в области геотехники.

Cut-off grade is perhaps the least understood driver of value for a mining operation. Many believe that it is determined relatively easily by knowing the mining and extraction costs, metallurgical recovery and an estimate of the price for the metal/s under consideration.

The earth is a giant system including the atmosphere, hydrosphere, lithosphere, biosphere, and the mantle, core and planetary space. Earth science is the study on the substance composition, origin, formation, evolution and the interaction of each part of the earth system. In the late 20th century, the earth science developed towards the earth system science, focusing on the lithosphere, and gradually extended to the relationship and interaction with the other layers.

Работа основана на материалах, полученных при анализе современного состояния растительности и животного населения гор Южного Урала, а также при изучении новых местонахождений ископаемых остатков позднего плейстоцена и голоцена в пещерах и торфяниках.

Ephemeral streams, dry washes, gullies, draws and arroyos are common names for a major element of Western landscapes. By definition ephemeral streams are characterized by short periods of flow, following local and intense rainfall, and alternating with long periods in which the channel is dry (Fig.] ,2).

Fossils are the remains or evidence of ancient life that we can see today. Scientists who study fossils are called paleontologists. By examining fossils, we can discover the types of animals and plants that lived on Earth long ago. <...>

In Chapter 2, Microseeps as Pathfinder and Regional Filtering Tool in Petroleum Exploration, Tedesco discusses the aid of microseeps in petroleum exploration. As shown in previous research (Tedesco, 1995), the use of surface geochemistry can enhance the probability of success from 10% to 60%.

This book is dedicated to the scientific compositional analysis of ancient ceramics. It provides theoretical and practical guidelines for their study via the techniques of thin section petrography, instrumental geochemistry, scanning electron microscopy and X-ray diffraction.

With over 400 photomicrographs of prehistoric, historic and traditional ceramics from 50 countries worldwide, as well as raw material specimens, ethnographic and experimental samples, it can be used as a reference manual for the identification and interpretation of the compositional and microstructural phenomena that occur within ancient ceramics. The detailed accompanying text and logical chapter structure means that it may also serve as a course book for specialist training in ceramic compositional analysis, as well as for self-study. <...>

Представлены данные по биогенной миграции стабильного стронция в таксонах биосферы, его содержанию в компонентах биогеохимической пищевой цепи, концентрированию морскими и сухопутными организ-мами. Рассмотрено поведение стронция в системе почва-растение-животные-человек. Систематизированы данные по биологической роли строн-ция и дана оценка реакций различных организмов на высокие концентрации стронция в среде и пищевой цепи. Показана роль биогеохимических и других факторов в этиологии уровской Кашина-Бека болезни. Обсуж-дены вопросы невыясненных сторон биологических функций стронция в организме млекопитающих в условиях усиливающихся масштабов техно-генеза биосферы, а также нормативы содержания стронция в объектах окружающей среды.
