Book Description

This is the first book in English reviewing and updating the geology of the whole Apennines, one of the recent most uplifted mountains in the world. The Apennines are the place from which Steno (1669) first stated the principles of geology. The Apennines also represent amongst others, the finding/testing sites of processes and products like volcanic eruptions, earthquakes, olistostromes and melanges (argille scagliose), salinity crisis, geothermal fluids, thrust-top basins, and turbidites (first represented in a famous Leonardo's painting). As such, the Apennines are a testing and learning ground readily accessible and rich of any type of field data. A growing literature is available most of which is not published in widely available journals.The objective of the book is to provide a synthesis of current data and ideas on the Apennines, for the most part simply written and suitable for an international audience. However, sufficient details and in-depth analyses of the various complex settings have been presented to make this material useful to professional scholars and to students of senior university courses. ...

Book Description

The major part of the world's high grade industrial manganeseore is being mined in supergene deposits. This book represents thefirst attempt to bring together not only academic but also commercialdata on all aspects of the geochemistry of formation of supergenemanganese ores. It is a distinctive account of the geology,geochemistry, mineralogy, experimental modelling studies, mechanismsof formation processes and geochemical evolution through geologicaltime of manganese ores for all types of supergene deposits. Specialemphasis is placed on the general geochemical model of supergenemanganese ore formation, which can be applied in geochemicalexploration. Despite the fact that supergene manganese ores have been used bymankind since the early centuries, it is only during the last decadethat a comprehensive understanding of the nature of geochemicalprocesses of formation of these deposits has become available andtheir potential as an economic resource has been recognized againstother genetical types of manganese accumulations. Audience: This substantial and comprehensive volume is ofinterest to economic geologists, mining engineers, geochemists,mineralogists and other specialized geoscientists. ... Read more

Book Description

The materials covered in the book include Amber and Copal; Jet; Ivory; Bone; Antler; Rhino horn; Horn; Tortoiseshell; Pearl; Shell; Coral, and other materials of plant and animal origin that have been used as gem or ornamental material.The book describes how to recognise them and how to distinguish them from the materials most commonly used to immitate them, for example plastic.

A comprehensive list of materials is included and each is presented with details of its origin, availability and conservation status, examples of, and a brief history of, their use. Organics fit together because of their origins, because they areconstantly used together, have similar histories and were the earliest gem materials used.

200 colour images are included for ease of reference and identification, allowing you to identify this material by sight, avoiding the usual gemological tests which ruin them.

Organics occur in modern and antique jewellery, in decorative items and in some furniture, and this book draws all the information together to provide the first complete overview of the subject.

* A unique reference book comprehensively documenting organic materials
* Highly illustrated colour filled book for ease of reference
* Learn the background and how to identify organic material ... Read more

Minerals Encyclopedia
By looking at various catalogs, there appear to be several editions or printings of this book, by the same two authors, under several similar titles, but having the same number of pages (296), and often (when mentioned) approximately the same number of photographs. My copy was published in 1999 by Rebo Productions, but may well be the very same as the others.

This is not really a textbook (one cannot use this to identify specimens), nor a full encyclopedia, as the species descriptions are brief. Includes many species, including some of the scarcer ones. The flyleaf says "over 600 mineral species and varieties, illustrated with about 750 color photographs" and an attempted count verifies that count; there are on the average from 2 to 3 color photographs on each page. These photographs are of macro mineral specimens (a few are of slightly micro specimens, crystals of the 1-5 mm range), and these photographs (at least in my copy, which is of glossy paper) are excellent, possibly the best that I have seen of such minerals in any publication, rivalling those of the periodical Mineralogical Record. Some of the photos are by J. Scovil, and the others are of equal quality. Captions of photos are not always very precise, although usually good enough.

Species arranged (in my edition) chemically, but there is an index; although in my edition only the A and B sections were translated from the Czech, most species names of minerals are close enough for this not to matter, and the index is quite useable, with the possible exception of quartz (an old mineral with its own name in various languages), but if one looks in the index under Agate, one can soon find it in the Oxides chapter.

Although, as a mineralogist (as I have sometimes been described) I buy few "coffee-table" books of photographs, and I am not sure whether this actually could fit into such a designation, this "Minerals Encyclopaedia" (as it is spelled in the edition I have) has such excellent color photographs that it is fully worth it for the photos alone. If all the printings are of this quality, and if you like the photos in Mineralogical Record, then you will probably like these also. ... Read more

Book Description

Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers. ... Read more
