Сборник представляет собой сводку многолетних поисковых и геолого-разведочных работ Научного института по удобрениям и инсектофунгисидам по фосфоритам Московской области.

В работе рассмотрены возможные изменения химического состава гидросферы от начальных до современных этапов ее существования. Доказывается, что эти изменения носили направленный необратимый характер. Рассмотрена эволюция литосферы, атмосферы и биосферы как факторов химической эволюции гидросферы. Особое внимание уделено круговороту солей в природе, а также галогеиезу, поскольку состав соленосных отложений и парагенетически связанных с ними рассолов дает надежную информацию о химических типах некогда существовавших морей. Доказывается, что в истории соленакоплеиия происходили не только изменения интенсивности солеобразования, но и направленные изменения вещественного состава соленосных отложений.
Монография предназначена для гидрохимиков, гидрологов, гидрогеологов, геологов, географов и работников смежных специальностей.

Geophysical techniques have many environmental, archaeological, forensic, geological, geotechnical, or engineering applications, as well as in the oil and gas, the mining industry, or for general academic research. Because of this, all the aspects connected with the logistics, designing, data collection, analysis, interpretation, and visualization, must be evaluated on a case-by case basis.

Studies on tetrabranchiate cephalopods have added much data to our understanding of the patterns and modes of evolution as displayed by fossil animals. Few invertebrate phyla show such marked periods of expansion in evolutionary intensity contrasted with periods of extreme contraction to the point of near extinction. The generalized evolutionary history of the ammonoids with periods of near extinction at the end of the Paleozoic and again at the end of the Triassic, and their final extinction at the end of the Cretaceous is well known. Among the nautiloid cephalopods a similar evolutionary history exists but with some important differences <...>

Given the unprecedented growth of human population over the past century, as well as the related increase in demand for and production of natural resources, it is evident that understanding the nature, origin and distribution of the world’s mineral deposits remains a strategic topic. The discipline of “economic geology,” which covers all aspects pertaining to the description and understanding of mineral resources, is, therefore, one which traditionally has been, and should remain, a core component of the university earth science curriculum. It is also the discipline that underpins the training of professional earth scientists working in the minerals and related industries of the world. A tendency in the past has been to treat economic geology as a vocational topic and to provide instruction only to those individuals who wished to specialize in the discipline or to follow a career in the minerals industry. In more recent years, changes in earth science curricula have resulted in a trend, at least in a good many parts of the world, in which economic geology has been sidelined <...>

In a broad sense, what one attempts to do in rock engineering is to anticipate the motion of a proposed structure under a set of given conditions. The main design objective is to calculate displacements, and as a practical matter, to see whether the displacements are acceptable. Very often restrictions on displacements are implied rather than stated outright. This situation is almost always the case in elastic design where the displacements of the structure of interest are restricted only to the extent that they remain within the range of elastic behavior. <...>

'A good collection of well-arranged trilobites looks better in the cabinet than perhaps any other fossils', wrote J.E. Taylor in Our Common British Fossils, published in 1885. Such is their popular appeal that trilobites have always been some of the most eagerly sought after of all fossils. Their name, suggested by their singular three-lobed appearance is derived from 'Trilobitae', introduced by the German naturalist Johann Walch in 1771 in his Der Naturgeschichte der Versteinerungen ('Natural History of Petrefactions'). The study of trilobites has particularly long associations with Wales, and the ancient rocks which crop out over much of the Principality have been well known as a rich source of them for nearly 300 years. This article outlines some of the history of their investigation in the area, describes their occurrence there, and discusses aspects of their nomenclature and morphology which are well illustrated by Welsh examples. <...>

В книге приведены инженерные методы расчета и конструирования струйных насосов н установок, их обобщенные рабочие и кавитационные характеристики. Рассмотрены схемные н конструктивные решения для различных установок с гидроструйными и лопастными (центробежными и вихревыми) насосами: гидротранспортных, вакуумных, для преобразования рабочих характеристик лопастных насосов и др.
Книга предназначена для инженерно-технических работников, занимающихся проектированием и эксплуатацией гидравлических, гндротранспортных, пневматических установок и систем в различных отраслях народного хозяйства.

Now that this book has been in use, through various editions, for more than 22 years, I must reflect on the many contributions that have ensured its success. Most particularly I must thank Bill Abriel, Rebecca Latimer, David Roberts, Greg Partyka, Malcolm Lansley, Les Denham, and Dave Agarwal for writing sections for me. Many people, too numerous to name, have kindly released data examples and discussed their interpretations with me. AAPG and SEG have cooperated in the book’s publication since the Fifth Edition. Anne Thomas has edited all editions. The high quality of the product depends significantly on her editorial expertise.

Монографiя присвячена вивченню фауни молюсків та стратиграфiї вижньокрейlових утворень Рівнинного Криму й Пiвнічного Причорномор"я. Вперше для цього регіону наведено монографічний опис понад 120 видiв стратиграфічно найважливiших груп викопних організмів: амонітів, белемнітів, двостулкових та черевоногих молюсків. Результати вивчення фауни дозволили встановити вік нижньокрейдових вiдкладів, деталізувати їх розчленування (для апта й альба - зональне) та провести регіональну кореляцiю розрізiв.
