This fully updated textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. It offers rules for quick and easy calculations based on the application of approximate data. It provides both the student and the geologist in the field with a complete set of rules and methods enabling them to perform a quick initial evaluation of the deposit without the support of specialists or computers - even if he is left to his own resources. All rules for calculations are illustrated with examples, and mistakes and pitfalls the authors encountered during their careers are pointed out.

Statistical evaluations of exploration data are the basis for decisions to be made at various stages of an exploration project. In contrast to other geostatistical books, Statistical Evaluations in Exploration for Mineral Deposits focuses not only on theory, but examples are also given, frequently originating from experience in mineral exploration by the author who worked worldwide for a mining company. Together with its companion volume, Economic Evaluations in Exploration, the book illustrates methods used in exploration campaigns and mining activities. It is intended as a vademecum for geologists who are forced to make quick decisions regarding an exploration project. It also addresses scientists and students involved in teaching or in mineral economic evaluations, recommendations or decisions.

Diese einzigartige Zusammenstellung gibt - vor dem Hintergrund globaler Umweltprobleme und der Einhaltung des Nachhaltigkeitsprinzips - einen aktuellen UEberblick uber die Leistungen, die Geologische Dienste fur ihre Burger bereithalten. Entscheidungstrager in Politik, Gemeinwesen, Lehre, Forschung und Unterricht erhalten anschauliche, reich illustrierte Detailinformationen zu den verschiedensten Bereichen des taglichen Lebens. Dies umfasst die klimatischen Bedingungen auf der Erde ebenso wie die Verfugbarkeit von (Trink-)Wasser und die Nutzung des Bodens, die Versorgung mit Rohstoffen sowie die Lagerung von Abfallen, aber auch die Beobachtung von Georisiken und Massnahmen zur Minderung ihrer Auswirkungen. Die modernen Aufgaben Geologischer Dienste beziehen ausserdem die UEberwachung von Atombombensprengungen sowie die Zusammenarbeit mit Entwicklungslandern ein.
