This book explains how microorganisms play a pivotal role in the formation of biominerals, including carbonates, silicate minerals and oxides. As readers will learn, these minerals may be produced either intracellularly or extracellularly in order to sustain microbial life. Experienced scientists from the field show that some of these biominerals can be produced in an active form, which involves direct enzymatic intervention to form precipitates. In addition, passive mineral formation can be mediated by the presence of dead cells. Readers from Microbiology and Biochemistry will appreciate the thorough coverage on various types of microbial mineral formation and their roles in microbial domains. Furthermore, they will benefit from the authors' first-hand knowledge regarding common techniques for studying biomineral-producing microorganisms, factors affecting biomineralization, and the use of this process in biotechnological applications.

This is the first book to provide a comprehensive treatment of theories and applications in the rapidly expanding field of the crystallography of modular materials. Molecules are the natural modules from which molecular crystalline structures are built. Most inorganic structures, however, are infinite arrays of atoms and some kinds of surrogate modules, e.g. co-ordination polyhedra, are usually used to describe them. In recent years the attention has been focused on complex modules as the basis for a systematic description of polytypes and homologous/polysomatic series (modular structures). This representation is applied to the modelling of unknown structures and understanding nanoscale defects and intergrowths in materials. The Order/Disorder (OD) theory is fundamental to developing a systematic theory of polytypism, dealing with those structures based on both ordered and disordered stacking of one or more layers. Twinning at both unit-cell and micro-scale, together with disorder, causes many problems, "demons", for computer-based methods of crystal structure determination. This book develops the theory of twinning with the inclusion of worked examples, converting the "demons" into useful indicators for unravelling crystal structure. In spite of the increasing use of the concepts of modular crystallography for characterising, understanding and tailoring technological crystalline materials, this is the first book to offer a unified treatment of the results, which are spread across many different journals and original papers published over the last twenty years.

Although Arab contribution to the sciences is generally well known in the Western world, Arab contributions to the study of gemology are less recognized because of the lack of English-language translations of notable Arab texts. Scarecrow Press is pleased to present Samar Najm Abul Huda's translation of Ahmad ibn Yusuf al Tifaschi's study of gems. Born in 1184, Al Tifaschi first learned about gems from his father, and augmented his knowledge through readings of Aristotle, Theophrastus, and Pliny, as well as through extensive travels to mines and trading centers. In 1253, he wrote what later became known as the most "methodical and complete" work on precious stones. Gemologists of today are still astounded by the advanced observations that Al Tifaschi made in this work. The book covers 25 different stones, giving the crystallographic forms and physical properties such as hardness, lustre, and dispersion. The book also describes causes of the formation of gemstones within their mother rocks as well as the characteristics of the mine concerned. Abul Huda's translation of the work includes notations on the translations of Al Tifaschi's work into other languages, as well as background information on Al Tifaschi's world, the well-known gemstones of the 13th century, the gemological terminology used by the medieval Arabs, and notations on other gemstones not mentioned by Al Tifaschi. Includes index, a general bibliography, and illustrations of two precious gemstones in their settings.

This book provides a wealth of geomathematical case history studies performed by the author during his career at the Ministry of Natural Resources Canada, Geological Survey of Canada (NRCan-GSC). Several of the techniques newly developed by the author and colleagues that are described in this book have become widely adopted, not only for further research by geomathematical colleagues, but by government organizations and industry worldwide. These include Weights-of-Evidence modelling, mineral resource estimation technology, trend surface analysis, automatic stratigraphic correlation and nonlinear geochemical exploration methods. The author has developed maximum likelihood methodology and spline-fitting techniques for the construction of the international numerical geologic timescale. He has introduced the application of new theory of fractals and multi fractals in the geostatistical evaluation of regional mineral resources and ore reserves and to study the spatial distribution of metals in rocks. The book also contains sections deemed important by the author but that have not been widely adopted because they require further research. These include the geometry of preferred orientations of contours and edge effects on maps, time series analysis of Quaternary retreating ice sheet related sedimentary data, estimation of first and last appearances of fossil taxa from frequency distributions of their observed first and last occurrences, tectonic reactivation along pre-existing schistosity planes in fold belts, use of the grouped jackknife method for bias reduction in geometrical extrapolations and new applications of the theory of permanent, volume-independent frequency distributions.

The evolution of geological cartography in Cuba in its more than 135 years of history has been possible through the consultation of numerous archival reports, publications, maps and personal interviews with different authors and geologists of vast experience. A brief critical analysis is made of the increase in the degree of geological knowledge of the country since the elaboration of the Geological Sketch of the Cuban Island at a scale of 1: 2 000 000 (Fernandez de Castro, 1883), first of Cuba and of Ibero-America, until the most recent Digital Geological Map of Cuba at scale 1: 100 000 (Perez Aragon, 2016). Cuba and its surroundings are a geological mosaic in the southeast corner of the North American plate with rocks from many different origins, from Proterozoic to Quaternary, extended along the southern border of the plate. From the Eocene, this belt has been dissected by several great faults, related to the development of some great oceanic depressions (Cayman trough and Yucatan basin). The fossil record of Cuba, which covers approximately the last 200 million years of life on Earth, is rich in very varied fossils, witnessing a wide diversity of organisms, both animals and plants, that inhabited the Antillean and Caribbean region; and that constitute the inheritance of the biological diversity that the current Cuban archipelago exhibits. As a result of the preparation of the Cuban Metallogenic Map at scale 1: 250 000, forty-one models and eight sub-models of metallic mineral deposits were identified. These models, of descriptive-genetic type, together with the analysis of their spatial distribution and their relationship with geology, allowed the identification and mapping of ten mineral systems, linked to the geodynamic environments present in the Cuban territory. Cuba has large deposits of limestone, loam, dolomite, kaolin, gypsum and anhydrite, rock salt, marbles, sands and clays of different types, zeolites, peat, therapeutic peloids and many more. There are manifestations of decorative and precious rocks such as jasper, jadeite, different varieties of quartz and even xylopals. A compilation of geochemical data of oceanic basalt samples from previous works, together with data of analyzed samples during this study in order to discuss geochemical criteria based on immobile element (proxies for fractionation indices, alkalinity, mantle flow and subduction addition), provide a comprehensive ophiolite classification according to their tectonic setting. This book addresses different facets of the geological knowledge of Cuba: history of its cartography, marine geology, fossil record, stratigraphy, tectonics, classification of its ophiolites, quaternary deposits, metallogeny and minerageny.

The book provides a model for structural evolution of the Himalaya with relevant background information so that earth scientists of other specialization will find it easy to comprehend. Hence the book is divided into two parts. The first part describes the basic principles of structural geology that are required to understand the evolutionary model described in the second part.

The book incorporates some of the ignored structural features, e.g. Pre-Himalayan rift tectonics, reactivation of faults, simultaneous development of folds and thrust faults, superposed folds, strike-slip faults developed during the early and superposed deformation, problems with the GPS data, erratic crustal shortening obtained by restoration of deformed sections, etc. The proposed model is essentially based on inversion tectonics and provides answers to some unsolved questions. It describes the accurate structure of the Himalaya as a primary arc. Supporting evidence for the model have also come from model deformation under controlled boundary conditions and anisotropy of magnetic susceptibility studies.

The sharp rise in mineral use has revived concern about scarcity. Economist John Tilton responds by analyzing recent trends in the consumption and availability of minerals that are most integral to the needs of modern civilization. He reminds readers that, if the arguments about scarcity sound familiar, it is because the story of minerals scarcity is almost as old as human history -- and so too is substitution and technological innovation. The issue at hand is the unprecedented acceleration in exploitation and use. Given global population growth, rising living standards, and environmental concerns, how seriously should today's society take the threat of mineral exhaustion?

On Borrowed Time? provides general interest and student readers with an accessible framework for understanding scarcity. Tilton defines important concepts and explores the methods used to study mineral scarcity, including physical measures of known reserves and the total resource base, and economic measures, such as extraction and end-user costs. He notes the increasing emphasis on the social and environmental costs of mineral production and use, placing the scarcity debate in context of broader concerns about sustainability and equity. He adds a history of thought about scarcity, from Malthus and Ricardo to Harold Hotelling, Donella Meadows, and present-day writers.

Modeling of Magmatic and Allied Processes presents methods and models for the quantification of geological processes. Conceptual models for magmatic differentiation involving crystallization and mixing are presented and applied to field and textural data. Model equations for the degree of partial melting in presence perturbations of lithospheric geotherms and partitioning of trace/radioactive elements in the matrix and melts, and the formation of continents with melt additions are described. Diverse magmatic products are shown to result from differentiation processes rather than magmatic source heterogeneities. The degree of partial melting depends on mantle temperatures, for which parameterized thermal convection models are reviewed. Perturbations in geotherms caused by mantle heat flow, CO2 flux from great depths and tectonic thrusting are analyzed. The petrogenetic significance of accessory minerals of felsic magma evolution is assessed with the help of examples from Carpathian granitoids. Methods for simulating the 3-D Concentration and Distribution Models (DC-DMs) and fractal dimension of evolving magma systems are described with examples. The use of conventional scanning electron microscopy methods and electron microprobe to characterize and infer magmatic processes is explained, and the background and economic potential of hydrothermal systems are examined. The nature of oxidizing felsic magmas along with their potential for copper mineralization is discussed. In closing, the handling, calculation and plotting of geochemical data for igneous rock suites using the R-language-based software Geochemical Data Toolkit (GCDkit) along with plug-in modules for the forward and reverse mass-balance calculation of fractional crystallization are demonstrated.
