As a country rich in mineral resources, contemporary China remains surprisingly overlooked in the research about the much debated ‘resourcecurse’. This is the first full-length study to examine the distinctive effects of mineral resources on the state, capital and labour and their interrelations in China. Jing Vivian Zhan draws on a wealth of empirical evidence, both qualitative and quantitative. Taking a subnational approach, she zooms in on local situations and demonstrates how mineral resources affect local governance and economic as well as human development.
История русской картографии охватывает период с начала появления первых сведений о русских землях вплоть до конца XVIII века. Подробна освещена эпоха рукописных карт, созданных картографами Европы и Азии до изображения печатного станка, работы западноевропейских и русских картографов до конца XVIII века, когда в России был создан Департамент карт, где централизованно создавались все карты страны
A study of the Soviet state reserves system is important to the US intelligence comnqunity in two ways. First, the nature and extent of state reserves must be considered in assessing the war potential of the USSR. Second, state reserves serve as a "flywheel'' in the operation of the Soviet planned economy, and a better understanding of the working of the Soviet economy may be obtained by studying them.
The formation and transformation of oceanic sediments involve geological, biological, physical and chemical processes. The knowledge of oceanic sediments and other objects of the Earth and Ocean Sciences therefore requires a multidisciplinary approach. This knowledge considerably increased during the past 50 years, closely following significant progress in the methods of investigation at sea and in the laboratory. In addition, ocean exploration is deeply rooted in History. Our understanding of the Ocean (including oceanic sediments and related processes) progressed step-by-step, following the evolution of techniques and ideas. Chapters 1 and 2 summarize the historical aspects of Oceanography (focusing on Marine Geology), along with the variety of processes that drive the formation and transport of sediment particles as well as their accumulation and transformation in oceanic sediments. <...>
The uranium minerals that today are at the centre of worldwide attention were unknown until 1780, when Wagsfort found a pitchblende sample in 10hanngeorgenstadt. This discovery passed unnoticed, however, since Wags fort thought that it contained a black species of a zinc mineral-hence the n':lme 'pitchblende' (= pitch-like blende). Seven years later, Klaproth, while examining the mineral, noted that it contained an oxide of an unknown metal, which he called 'uranium' in honour of the planet Uranus, recently discovered by Herschel. Klaproth also believed that he had separated the metal, but, in fact, the attempt failed, and uranium, given its strong affinity with oxygen, was not separated until several years later. In 1833 Arfwedson attempted the separation and, in so doing, reduced the pitchblende. His attempt was not successful and only U02 was obtained. It was Peligot, in 1840, who was finally successful. He managed the reduction of the metal working with metallic potassium. It should be remembered that twelve years earlier Berzelius had isolated thorium.
In 1983 the Nuclear Energy Agency of the Organisation for Economic Cooperation and Development (OECD/NEA) and the IAEA jointly published a book on Uranium Extraction Technology. A primary objective of this report was to document the significant technological developments that took place during the 1970s. The purpose of this present publication is to update and expand the original book.
Structural geology is obviously one of the more important subjects for geoscientists working in petroleum industry. Folds and faults in deformed rocks make traps for hydrocarbon accumulation. Also, large-scale deformations, the so-called tectonics, control the architecture of petroliferous sedimentary basins. It is the primary job of a structural geologist to interpret geological map and field data, and infer geometry of large scale folds and faults. However, geoscientists with varied specializations and working with different kinds of data may also be called upon to make structural interpretations.
The basic structural building block of the biomarkers is the isoprene unit (Figure 1A). The end closer to the methyl branch is called the "head/' and the other end is the "tail." Compounds formed biosynthetically from isoprene units are called "isoprenoids." Two isoprene units joined head-to-tail (with minor modifications, such as hydrogenation of double bonds) form a monoterpane (Figure IB). Two monoterpanes (four isoprene units) linked together form a diterpane, whereas six isoprene units can be joined either to form a sterane or a triterpane, depending upon how the linking is accomplished.
In 1916, the first generation of geological graduates entered the China Geological Survey and opened a new era of geological survey in China. Over the past 100 years, generations of geologists have made outstanding contributions to the geological survey and prospecting for China’s prosperity. They measure the ground, search for treasures, explore the earth, and engrave the beautiful mountains and rivers.
