This book starts with conversions. Although the metric system is being adopted worldwide, older data from Anglo-American countries will always be non-metric. Any deposit evaluation should be based on solid historical research. Many deposits have a long exploration history. Meticulous investigation of older data often answers many questions and avoids mistakes.
In addition, uncommon units used in the raw materials field are introduced.

Thereafter the book generally follows the usual steps of an evaluation: Assessment of tonnage and grades; conversion of geological data into mining data; derivation of a commodity price; calculation of return per tonne of ore; determination of optimum mine capacity; estimation of capital and production costs; final economic evaluation as appropriate for early stage projects.

The book ends with four chapters dealing with aspects of general interest to economic geologists and mineral economists: Valuation of exploration projects without mineralization, comparison of deposits, calculations of growth rates and equity

The book sets out to present a state of practice of the geotechnical engineering of embankment dams and their foundations and the geotechnical engineering of the foundations of concrete dams. It assumes that the reader is trained in Civil Engineering or Engineering Geology, with knowledge of soil and rock mechanics.

‘Orebody modelling and strategic mine planning’ are arguably the backbone of our industry and represent an intricate, complex and critically important part of mining ventures. They have a profound effect on the value of a mine, as well as determining the technical plan to be followed from mine development to mine closure.
It is most gratifying to introduce the second revised edition of this Spectrum Series volume on the above topic, following the depletion of all copies of the first edition within about a year of its publication.

Cet Atlas de Pétrologie s'adresse en premier lieu à tous les étudiants engagés en cursus de Licence dans les domaines des sciences de la vie et de la Terre. Construit sous forme de fiches en double page et abondamment illustré, cet ouvrage offre une vision synthétique sur un ensemble de minéraux et de roches magmatiques, sédimentaires et métamorphiques, les plus fréquemment rencontrés et dont la reconnaissance fait l'objet de séances de travaux pratiques. li est aussi l'occasion de découvrir les roches extraterrestres avec l'étude des météorites et d'aborder certains domaines de la géologie appliquée avec l'étude de ressources naturelles dans leurs gisements et leurs utilisations. <...>

The rapid progress of mechanised tunnelling to market leadership has continued – even exceeded predictions; the general worldwide trend in construction towards mechanisation and automation clearly demanded a similar development in tunnelling. It is significant that even in Austria, the traditional home of the New Austrian Tunnelling Method (NATM), mechanised tunnelling has also established its position in the last decade.

Many of the methods now used for gold extraction are based on techniques that have been known or established for centuries. Gravity concentration, amalgamation, cyanide leaching, chlorination, zinc precipitation, and carbon/charcoal adsorption are all processes that have been used for at least a hundred years, and combinations of these remain as the basis for most gold recovery flowsheets.

Geostatistics aims at providing quantitative descriptions of natural variables distributed in space or in time and space. Examples of such variables are 

Ore grades in a mineral deposit 

Depth and thickness of a geological layer 

Porosity and permeability in a porous medium 

Density of trees of a certain species in a forest 

Soil properties in a region 

Rainfall over a catchment area 

Pressure, temperature, and wind velocity in the atmosphere
Concentrations of pollutants in a contaminated site

This book arose from a series of lectures given at the Universities of Cambridge and Oxford during the Spring of 1966. The lectures were based on material compiled by the author between 1961 and 1965 and submitted in a Ph.D. dissertation to the University of California at Berkeley. At the time crystal field theory had become well established in chemical literature as a successful model for interpreting certain aspects of transition metal chemistry.
