An introduction to applied geostatistics

This began as an attempt to write the book that we wish we had read when we were trying to learn geostatistics, a task that turned out to be much more difficult than we originally envisaged. To the many people who provided encouragement, support, and advice throughout the writing of this book, we are very grateful.

We owe a lot to Andre Journel, without whom this book would never have been written. In addition to providing the support necessary for this project, he has been an insightful technical reviewer and an energetic cheerleader.

An introduction to igneous and metamorphic petrology / Введение в петрологию магматических и метаморфических пород

This text is designed for use in advanced undergraduate or early graduate courses in igneous and metamorphic petrology. The book is extensive enough to be used in separate igneous and metamorphic courses, but I use it for a one-semester combined course by selecting from the available chapters. The nature of geological investi-gations has largely shaped the approach that I follow.

An introduction to metamorphic petrology / Введение в петрологию метаморфических горных пород

Metamorph;c processes have been taking place on a massive scale throughout the Earth's history, and have affected the bulk of the rocks now present in the crust. Despite this, they are not as well understood as sedimentary or volcanic processes, because metamorphism can scarcely ever be observed directly, and the study of metamorphic rocks is instead based on observation, inference and logic, founded in relatively simplistic experimental studies and the basic principles of chemistry and physics

An introduction to the rock-forming minerals / Знакомство с породообразующими минералами

The members of the olivine group crystallize with orthorhombic symmetry, the structures consisting of independent SiO4 tetrahedra linked by divalent cations in six-fold coordination. In the (Mg,Fe)-olivines there is complete solid solution between Mg2SiO4 (forsterite) and Fe2SiO4 (fayalite); similarly the (Fe,Mn)-olivines form a continuous series. Olivine is a major constituent of ultrabasic plutonic rocks and olivines of metamorphic origin occur principally in rocks of ultramafic composition, in impure carbonates and in iron-rich sediments.

Analysis and control of oilwell drilling vibrations. A time-delay systems approach / Анализ и контроль вибраций при бурении скважин. Анализ систем смещения времени ("время запаздывания")

Vibrations in mechanical systems are oscillations occurring without being intentionally provoked. They often have detrimental effects on the system performance and may cause premature wear of the system components, underperforming processes, and could even involve security problems, such is the case in aircraft wings; which in the worst case scenario, excessive vibration causes the aircraft to crash.

In oilwell drillstring systems, vibrations constitute an important source of economic losses; drill bit wear, pipes disconnection, borehole disruption and prolonged drilling time, are only some examples of consequences associated with drilling vibrations.<...>

Anatomy of porphyry-related Au-Cu-Ag-Mo mineralised systems: Some exploration implications

Analyses of exploration and mining case studies as well as magmatic arc geothermal systems have facilitated an understanding of the implications to explorationists of the anatomy of porphyry related Au-Cu-Mo-Ag mineralising systems. Deeply eroded magmatic source rocks tend to host sub economic mineralisation, which may become focused in the highly prospective in overlying apophyses to spine-like polyphasal intrusions. Buried targets may be identified by analyses of zoned alteration and mineralisation developed by complex overprinting relationships. Mineralised fluids may exit from the magmatic source migrating to higher crustal levels to form epithermal deposits. High sulphidation epithermal Au + Cu + Ag deposits display characteristic alteration and mineralisation zonation which aids target generation and in some instances evolve to host marginal and overprinting lower sulphidation ores which display improved metallurgy and metal grades. Low sulphidation epithermal Au-Ag deposits are categorised as a number of styles, linked on an overall anatomy, which display considerable variation in metal grade, size, form and metallurgy, typically governed by setting and crustal level of formation, as well as controls to vein formation such as: host rock competency, structure, and mechanism of Au deposition. All these controls and zonation pattern vectors provide valuable tools to explorationists in the search for hidden ores.

Annales geologiques du service des mines. Recherches sur les faunes albiennes de Madagascar

Dans un mémoire, qui a été publié dernièrement dans les Annales géologiques du Service des Mines de Madagascar (1), j'ai décrit une faune albienne remarquable, caractérisée par l'abondance des Ammonites des Genres Douvillei-ceras, Lemuroceras et Brancoceras, et j'ai donné une coupe, selon Henri Besairie, du gisement principal de ces fossiles, situé dans la région d'Ambarimaninga, cercle de Sitampiky (Madagascar).

Au sommet de la coupe, c'est-à-dire au-dessus des couches principales à Ammonites que j'ai rapportées au sommet de l'Albien inférieur (Dou-villeicératien) et à la base de l'Albien moyen (partie inférieure de l'Oxytropidocératien) suivant l'échelle stratigraphique établie par Maurice Breistroffer (2), existe un banc fossilifère à Echinides épais de 1 m, où Henri Besairie a recueilli de très nombreux Oursins qui font l'objet du présent mémoire.

Applied clay mineralogy. Occurrences, processing and application of kaolins, bentonites, palygorskite-sepiolite, and common clays / Минералогия глин. Возникновение, переработка и применение каолинов, бентонитов, палыгорскит-сепиолитов и обычных глин

Clays and clay minerals are very important industrial minerals. There are well over one hundred documented industrial applications of clay materials. Clays are utilized in the process industries, in agricultural applications, in engineering and construction applications, in environmental remediations, in geology, and in many other miscellaneous applications. This book is an assimilation of the major and minor uses of clays and clay minerals and explains why an understanding of the structure and physical and chemical attributes of the individual clay minerals are so important. Clay is an abundant raw material which has an amazing variety of uses and properties that are largely dependent on their mineral structure and composition. Other than the clay structure and composition, there are several additional factors which are important in determining the properties and applications of a clay. These are the non-clay mineral composition, the presence of organic material, the type and amount of exchangeable ions and soluble salts, and the texture (Grim, 1950) <...>
