Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
The deposit is situated in southeastern New South Wales at Lat.35°04*S, Long.1A9°34*E. (Fig.l) The first phase of testing proved up a body of poljmietallic massive sulphides and an adjacent zone of dominantly copper ore. The massive sulphides body consisted of about 6.3 million tonnes of copper, lead and zinc ore (1.7% Cu: 5.5% Pb; 14.4% Zn) and was the main target for geophysical investigation. The copper ore zone contains about 3.7 million tonnes averaging about 1.9% Cu, 0.1%Pb, 0.5% Zn in a number of ore shoots both along strike from and below the massive sulphides. Subsequent drilling indicated several concealed bodies of massive sulphides, separate from the first discovered body but these are at depths of more than 200m and hence too deep to have influenced the geophysical investigations. <...>
The Tropicana-Havana gold deposit is hosted by Archaean rocks that lie along the eastern margin of the Yilgarn Craton, Western Australia. The Mineral Resource for the project is 75.3 million tonnes grading 2.07 g/t for 5.01 Moz of gold. Gold mineralisation postdates peak granulite-facies metamorphism and formed from variably oxidised, higher temperature (>350˚C), silica-undersaturated fluids.
The objective of the Australian groundwater modelling guidelines is to promote a consistent and sound approach to the development of groundwater flow and solute transport models in Australia. It builds on existing guidelines (Murray–Darling Basin Commission 2001) that have been adopted throughout Australia in recent years. While it is acknowledged that the term groundwater modelling refers to a variety of methods, the guidelines focus on computer-based numerical simulation models.
Магматические гидротермальные флюиды в осадочных вмещающих породах, связанное с интрузиями золо-медное месторождение Телфер, Ороген Патерсон, Западная Австралия: Ограничения давления, температуры и состава рудообразующих флюидов
The Neoproterozoic Telfer deposit, one of Australia’s largest gold-copper deposits, is located in the Paterson orogen. Several highly differentiated calc-alkaline to alkali-calcic peraluminous granites intruded the metasedimentary rocks near (5–20 km) Telfer contemporaneously with structurally controlled gold-copper mineralization. Fluid inclusion assemblages with different fluid inclusion types were identified in samples from a range of different vein types.
The papers in this book are the early results of a research program on sedimentation in Shark Bay which is being carried out from the Department of Geology, The University of Western Australia. The investigation is directed toward an understanding of processes responsible for the formation and early diagenesis of carbonate sediments. Particular emphasis has been placed on development of sedimentary facies and processes in the context of sea-level changes and evolution of the hydrologic environment during the latter part of the Quaternary. Shark Bay, which lies between latitudes 24°30’ and 26°45’S on the arid western coast of Australia, has the dimensions of a minor epicontinental sea; it has an area of about 5,000 sq mi and an average depth of 30 ft. The embayment offers exceptional opportunities for research in carbonate sedimentation since there is a wide range of environments, biotic communities, and sediment types available for study. Carbonate deposition is predominant, and sedimentation is controlled by hydrologic factors, waves, currents, and organisms. Organisms play a major role in sedimentation by contribution of skeletal parts and by intervention in sedimentation. <...>
Рассмотрены результаты комплексных исследований уникальных месторождений урана в Северной Австралии, приуроченных к структурному несогласию между ранним и средним протерозоем, тектоническая позиция урановорудного района Аллигейтор-Ривер и структурно-литологические условия локализации составляющих его рудных объектов. Детально разобраны минералого-геохимические особенности урановых руд, околорудных магнезиальных метасоматитов и вмещающих пород, включая многочисленные изотопные и термобарогеохимические данные. Интерес к поискам аналогичных рудных объектов в СССР определяет актуальность работы.
Книгой А.Киста «Австралия и острова Тихого океана» издательство продолжает серию книг «Континенты, на которых мы живем». Как и уже вышедшие в свет «Африка», «Южная и Центральная Америка», «Северная Америка», этот том дает широкое представление об исключительно своеобразной природе столь далекого от нас континента, а также еще более далеких островов Тихого океана. Издание богато иллюстрировано, в нем свыше ста оригинальных цветных и черно-белых фотографий
Information on soil and land resources is a prerequisite for informed decisions on land use and management. Procedures for acquiring and using this information are introduced and emphasis is given to a balanced approach with elements of mapping, modelling and monitoring within the broader context of environmental change. The conceptual basis for a range of approaches to survey is introduced along with an assessment of strengths and weaknesses. A framework for dealing with scale in measurement and prediction is then introduced.
