Чрезвычайный разворот горной и, в частности, каменноугольной промышленности СССР сопровождается введением новых методов разработки. Усиливается пользование механизмами, Происходит укрупнение отдельных производственных единиц вместе с увеличением числа подземных и поверхностных рабочих.

Metamorphic rocks make up much of the deeper parts of orogenic belts. The minerals and mineral assemblages present in these rocks contain information about the conditions of formation of the rocks. This information may be used to decipher parts of the tectonometamorphic processes that were involved in the formation of the rocks. The unravelling of the conditions of formation is therefore important if the tectonothermal history of an orogen is to be determined <...>

Академик, Александр Евгеньевич Ферсман — выдающийся советский минералог, геохимик и географ — широко известен советскому читателю, чему способствовали не только его замечательная исследовательская и практическая работа, но и популяризация геологической науки.

В книге в популярной форме изложены сведения о золоте: его свойствах, распространении в природе, формировании месторождений, об истории открытия и разработки месторождений. Рассмотрены этапы развития добычи золота с древнейших времен до наших дней, приведены данные о его потреблении, затронуты проблемы, связанные с получением золота в будущем.
Книга рассчитана на широкий круг читателей.

На основе большого фактического материала изложены подходы к использованию результатов геохимического картирования для оценки экологического ущерба.
Для специалистов природоохранных организаций, административных органов, организаций и предприятий.

На основе изучения литохимических аномалий в первичных и вторичных поисковых обстановках рассмотрены проблемы количественного геохимического эталонирования рудных объектов как геохимически взаимосвязанных природных систем. Детально описан механизм преобразования аномалий в процессах гипергенеза и охарактеризована геохимическая подвижность элементов-индикаторов в ореольных зонах выщелачивания.
Для геохимиков и геологов, занимающихся поисками и разведкой рудных месторождений.

Conventional oil and gas are usually found in pore spaces and fracture openings of sandstones, limestones, and dolomite. Shales, although considered to be important in many cases as source rocks and cap rocks for hydrocarbons, usually do not contain commercial oil and gas. In other words, from the standpoint of production, shales are relatively useless rocks.

If, for example, an exploratory well were drilled and a geologist tried to evaluate whether it had penetrated oil and/or gas accumulations, he would first separate the shaly sections as being of no interest, and then try to find out whether the other sections were oil-(and/or gas-) saturated or watersaturated. <...>

Our primary interest is to consider three-dimensional flow in porous media, including fissured and layered media. We propose to provide for extraction or injection of fluids via points th at are complicated in geometry for a variety of conditions on the boundaries of the porous solid. Here, we preview our notation and address a few basic issues for ease of understanding.

The fundamental question underlying marine geochemistry is, ‘How do the oceans work as a chemical system?’ At present, that question cannot be answered fully. The past four decades or so, however, have seen a number of ‘quantum leaps’ in our understanding of some aspects of marine geochemistry. Three principal factors have made these leaps possible:
1    advances in sampling and analytical techniques;
2    the development of theoretical concepts;
3    the setting up of large-scale international oceanographic programmes (e.g. DSDP, MANOP, HEBBTE, GEOSECS, TTO, VERTEX, JGOFS, SEAREX, WOCE), which have extended the marine geochemistry database to a global ocean scale. <...>

Ammonites are an extinct and charismatic lineage that persisted for over 300 million years. They were used, with other fossils, to corroborate the principle of faunal succession and launch the field of biostratigraphy. Despite intense research, many important questions remain unanswered. Furthermore, outdated hypotheses persist. Many new findings include a better understanding of their appearance in life, their locomotion, and their

role in long-gone ecosystems. Of course, there are still controversies, e.g., why did shell complexity increase during evolutionary history. This richly illustrated book describes the full range of ammonoids and their fascinating evolutionary history.
