Prehistoric Gold in Europe
Author: Giulio MorteaniPublisher: Springer Science & Business Media
ISBN: 9401512922
Category : Technology & Engineering
Languages : en
Pages : 604
Book Description
Interest in the study of early European cultures is growing. These cultures have left us objects made of gold, other metals and ceramics. The advent of metal detectors, coupled with improved analytical techniques, has increased the number of findings of such objects enormously. Gold was used for economic and ceremonial purposes and thus the gold objects are an important key to our understanding of the social and political structures, as well as the technological achievements, of Bronze and Iron Age European societies. A correct interpretation of the information provided by gold and other metal objects requires the cooperation of experts in the fields of social, materials and natural science. Detailed investigation of gold deposits in Europe have revealed the composition and genesis of the deposits as sources of the metal. In Prehistoric Gold in Europe, a group of leading European geoscientists, metallurgists and archaeologists discuss the techniques of gold mining and metallurgy, the socioeconomic importance of gold as coinage and a symbol of wealth and status, and as an indicator of religious habits, as well as a mirror of trade and cultural relations mirrored by the distribution and types of gold objects in prehistoric times.

Ore Geology and Industrial Minerals
Author: Anthony M. EvansPublisher: John Wiley & Sons
ISBN: 1118685024
Category : Science
Languages : en
Pages : 400
Book Description
Much new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.

Pyrite

ISBN: 0190203692
Category : Science
Languages : en
Pages : 329
Book Description
Most people have heard of pyrite, the brassy yellow mineral sometimes known as fool's gold. Pyrite behaves like stone and shines like metal, and its dual nature makes it a source of both metals and sulfur. Despite being the most common sulfide mineral on the earth's surface, pyrite's bright crystals have attracted the attention of many different cultures, and its nearly identical visual appearance to gold has led to tales of fraud, trickery, and claims of alchemy. Pyrite occupies a unique place in human history: it became an integral part of mining culture in America during the 19th century, and it has a presence in ancient Sumerian texts, Greek philosophy, and medieval poetry, becoming a symbol for anything overvalued. In Pyrite, geochemist and author David Rickard blends basic science and historical narrative to describe the many unique ways pyrite is integral to our world. He explains the basic science of oxidation, showing us why the mineral looks like gold, and inspects death zones of present oceans where pyrite-related hydrogen sulfide destroys oxygen in the waters. Rickard analyzes pyrite's role in manufacturing sulfuric acid and discusses the significant appearance of the mineral in literature, history, and the development of societies. The mineral's influence extends from human evolution and culture, through science and industry, to our understanding of ancient, modern, and future earth environments. Energetic and accessible, Pyrite is the first book to show readers the history and science of a mineral that helped make the modern world.
Framboids
Author: David RickardPublisher: Oxford University Press
ISBN: 0197571921
Category : Science
Languages : en
Pages : 320
Book Description
Framboids may be the most astonishing and abundant natural features you've never heard of. These microscopic spherules of golden pyrite consist of thousands of even smaller microcrystals, often arranged in stunning geometric arrays. They are rarely more than twenty micrometers across, and often look like miniscule raspberries under the microscope. The formation of a framboid is the result of self-assembly of pyrite micro- and nano-crystals under the influence of surface forces. They can be found all around us in rocks of all ages and present-day sediments, soils, and natural waters. Our planet makes billions every second and has been doing so for most of recorded geologic time. As a result, there are more framboids on our planet than there are sand grains on Earth or stars in the observable universe. The microscopic size of framboids belies their importance to contemporary science. They help us better understand inorganic self-assembly and self-organization, and studying them illuminates Earth's evolutionary history. In this book, David Rickard explains what framboids are, how they are formed, and what we can learn from them. The book's thirteen chapters trace everything from their basic attributes and mineralogy to their biogeochemistry and paleoenvironmental significance. Rickard expands on the most updated research and recent developments in geology, chemistry, biology, materials science, biogeochemistry, mineralogy, and crystallography, making this a must-have guide for researchers.
