Lithology, Mineralogy, and Geochemistry of Glacial Sediments Overlying Kimberlite at Smeaton, Saskatchewan


Book Description

The investigation summarized in this report was designed as a case study regarding the frequency & chemistry of kimberlite indicator minerals in Pleistocene glacial sediments from a kimberlite field and a vertical profile of data that could be compared to surface till data. The study site was located near Smeaton in central Saskatchewan underlain by Lower Cretaceous sedimentary rocks interbedded with extrusive kimberlitic debris. Cores were obtained from the upper part of the Cretaceous sequence and from the overlying Quaternary sequence, and laboratory studies were carried out on the core lithology, matrix carbonate content, mineralogy, and geochemistry. Results are presented regarding sediment unit descriptions, bulk mineralogy of sediment-derived concentrates, kimberlite indicator minerals, visible gold, geochemistry, and borehole logging. The provenance of the sedimentary sequences is discussed along with the implications for diamond exploration.







Drift Exploration in Glaciated Terrain


Book Description

This volume describes the use of till geochemical and indicator mineral methods for mineral exploration in the glaciated terrain of Canada. The principles and examples described in this volume will have direct applications for exploration companies looking for diamonds, precious and base metals and uranium in glaciated parts of North America, northern Europe and Asia and mountainous regions of South America.

Drift Prospecting


Book Description

Collection of papers presented in 1987, showing a variety of types of research being carried out in different geological settings in Canada and Finland. The papers indicate the value of grassroots studies in glacial geology and how the basis for drift prospecting is a thorough understanding of the provenance, stratigraphy, and ice flow directions of glacial sequences, backed by data on the geochemistry, lithology, and mineralogy of glacial sediments. Abstracts are included for each paper.




Mineral Resources


Book Description

This comprehensive textbook covers all major topics related to the utilization of mineral resources for human activities. It begins with general concepts like definitions of mineral resources, mineral resources and humans, recycling mineral resources, distribution of minerals resources across Earth, and international standards in mining, among others. Then it turns to a classification of mineral resources, covering the main types from a geological standpoint. The exploration of mineral resources is also treated, including geophysical methods of exploration, borehole geophysical logging, geochemical methods, drilling methods, and mineral deposit models in exploration. Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel’s estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV, IRR, and PP, estimation of risk, and software for evaluating mineral resources). It subsequently describes key mineral resource exploitation methods (open pit and underground mining) and the mineral processing required to obtain saleable products (crushing, grinding, sizing, ore separation, and concentrate dewatering, also with some text devoted to tailings dams). Lastly, the book discusses the environmental impact of mining, covering all the aspects of this very important topic, from the description of diverse impacts to the environmental impact assessment (EIA), which is essential in modern mining projects.




Diamond Exploration Techniques Emphasising Indicator Mineral Geochemistry and Canadian Examples


Book Description

The Canadian Shield and adjacent areas underlain by cratonic rocks are a highly prospective geologic environment for diamonds. This volume reviews the genesis of diamonds and the petrology of kimberlites and lamproites, the major diamond-bearing rock types. It then describes diamond exploration techniques, focusing on the use of indicator minerals as a means of identifying prospective areas. Topics covered include major-element geochemistry of indicator minerals, eclogitic paragenesis, and trace element techniques. The volume also discusses the indicator mineral geochemistry results from a study of 18 localities around the world. In addition, since conventional indicator mineral techniques are not always applicable to lamproite exploration, alternative pathfinder minerals are reviewed.
