This book was released on 2016 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of whether or not it is possible to trace the signature of alteration haloes surrounding deep-seated unconformity-type U mineralization through thick Quaternary tills is one of great importance for those conducting exploration in glaciated areas. The geochemical signals associated with alteration are often subtle and subject to numerous sources of noise, and multi-till stratigraphies can completely mask or truncate dispersal patterns. To study glacial dispersal from alteration zones surrounding unconformity-type uranium mineralization, this study focuses on a deep-seated (>100 m) basement-hosted unconformitytype U mineralized body known as Tatiggaq, which is located in the Thelon Basin of Nunavut. The Tatiggaq area presents an ideal opportunity to investigate this problem, since the area is blanketed by a thick (12-34 m) multi-till stratigraphy, mineralization does not intersect the bedrock-till interface, and the mineralization is surrounded by an extensive illitic alteration halo that reaches the bedrock surface. The recovery of till samples from diamond drill core from the multi-till stratigraphy overlying the subcropping alteration halo provides a unique opportunity to model glacial dispersal and identify whether the fingerprint of buried alteration can be traced through three dimensions to the modern day surface. Sampling of till recovered during diamond drilling was combined with the sampling of surficial mudboils in the area surrounding Tatiggaq to trace the dispersal of alteration. The drill core samples were collected from four stratigraphic units that were deposited by early southwesterly and southerly ice flows, followed by a reversal in ice flow towards the northwest and westnorthwest. Knowledge of the till stratigraphy directly above the Tatiggaq alteration zone was used to construct a three dimensional model of the sediments overlying bedrock to allow the tracing of alteration through the subsurface. The geochemical fingerprint of the alteration halo at Tatiggaq was identified by applying univariate and multivariate statistical analysis, including principal component analysis, to geochemical data from altered and fresh rocks in the region. This analysis identified the enrichment of Fe2O3, K2O, Al2O3, P2O5, TiO2, B, Ni, U, Cr, and Sc, and depletion of CaO, MnO, Na2O, Mo, Zn, Ba, and Sr in the altered rocks using total digestion of rock powders (HF-HClO4-HNO3). Partial digestion of the same rock powders using HNO3-HCl identified the enrichment of U and depletion of V, Zn, Y, and Yb in the altered rocks. The observed trends in the bedrock data were then applied to the till geochemistry data to identify alteration signatures that were discernible across the till stratigraphy.

This book was released on 2016-12-16 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together an overview of the recent geological history, active earth and biological processes and human settlement of New Zealand. Topics covered include the very active neotectonic and volcanic setting. Mountain geomorphic processes are examined and new ideas about landsliding are highlighted. The exceptional sedimentary archives of the Whanganui Basin are also presented. As one of two land masses that extend into the southern mid-latitudes, New Zealand is ideally located to investigate changes in Southern Ocean climate. Related to this, mountain glaciation in New Zealand is a focus in global climate change debates. New Zealand also has a unique biota due to its long isolation and is the last major land mass to be settled by people. Advances in DNA technologies have revolutionised our understanding of the histories and processes involved. The book provides a comprehensive review of existing work and highlights new ideas and major debates across all these fields.

Download or read book Geology and Resource Potential of the Congo Basin written by Maarten J. de Wit and published by Springer Science & Business Media. This book was released on 2015-01-02 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the geomorphology, geology, geochronology, geophysics and mineral resources of the Congo Basin, one of the world’s most enigmatic and poorly understood major intra-continental sedimentary basins, and its flanking areas of Central Africa. It provides an up to date analysis of the large region’s origin and evolution. The book’s nineteen chapters take the reader through the entire basement history, as well as the Basin’s ca. 700 million years of cover sequences. Starting from its Archean cratons and Proterozoic mobile belts, and proceeding through the Phanerozoic sequences, including the most recent Cenozoic successions, the book also explores the present drainage systems and the subtle but complex topography of the Congo Basin. It also presents and evaluates new basin models and related dynamic processes, as well as revised correlation schemes with its Gondwana counterparts in South America, all of which provide key insights into its rich diamond deposits and other mineral wealth, which are documented in the final chapters. A specific feature of this book is its synthesis, performed by teams of active experts, of a vast amount of geoscientific data previously only recorded in research reports, company reports, survey bulletins, and scattered journal articles and books. The sheer size of the Congo Basin (ca.1.8 million km2, or just under half the area of the EU) and Central Africa (some 7 million km2, or more than 70% of the area of the USA) will make this a sought-after source of information and inspiration on this unique region.

Available in PDF, EPUB and Kindle. Book excerpt: Is it not generally believed that our town is a healthy place . . . a place highly com mended on this score both for the sick andfor the healthy? . . And then these Baths - the so-called 'artery' of the town, or the 'nerve centre' . . . Do you know what they are in reality, these great and splendid and glorious Baths that have cost so much money? . . A most serious danger to health! All that filth up in Melledal, where there's such an awful stench - it's all seeping into the pipes that lead to the pump-room! Henrik Ibsen, An Enemy of the People, 1882 Henrik Ibsen gave the 'truth about mineral water' more than 100 years ago in An Enemy of the People. His examples came not from the decadent bathing spas of Bohemia or Victorian Britain, but from the very edge of polite society, subarctic Norway! His masterpiece illustrates the central role that groundwaters and, in particular, mineral waters have played in the history of humanity: their economic importance for towns, their magnetism for pilgrims searching for cures, the political intrigues, the arguments over purported beneficent or maleficent health effects and, finally, their contami nation by anthropogenic activity, in Ibsen's case by wastes from a tannery. This book addresses the occurrence, properties and uses of mineral and thermal groundwaters. The use of these resources for heating, personal hygiene, curative and recreational purposes is deeply integrated in the history of civilization.
Download or read book Mineral Resources written by Manuel Bustillo Revuelta and published by Springer. This book was released on 2017-08-23 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Young Earth written by Euan G. Nisbet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'What are we going to do with a parcel of old stones?' wrote the director of an African museum a century and a half ago, when one of my ancestors presented him with a splendid collection of fossils of mammal-like reptiles. Old stones, however intriguing, are difficult to interpret, dusty, and do not fit well in the neatly ordered contents of a house of learning. Archaean geology, which is the study of the Earth's history in the period from after 9 the end of planetary accretion (4.5-4.4 x 10 years ago) up to the beginning 9 of the Proterozoic (2.5 x 10 years ago) is much the same - a parcel of old stones seemingly impossible to understand. Yet these stones contain the history of our origins: they can tell us a story that is interesting not just to the geologist (for whom this book is primarily written) but instead addresses the human condition in general.
