Dieses allgemein verständliche Buch gibt Antworten auf folgende Fragen: Wo sind Erze für Metalle, wo ist Erdöl zu finden? Der Verbrauch an mineralischen Rohstoffen ist in den letzten Jahrzehnten immer schneller gestiegen, doch die Ressourcen sind begrenzt und der Aufwand, neue Lagerstätten ausfindig zu machen, nimmt zu. Damit wird die Frage, wie Lagerstätten entstehen und wie sie aufzuspüren sind, immer wichtiger. Warum gibt es Kupfer in Chile und in der Lausitz? Wie wichtig ist die Atacamawüste für Elektroautos? Wie unterscheiden sich die Vorkommen von Seltenerdelementen in China und Grönland? Wo liegen die größten Platinreserven, und wozu wird dieses Edelmetall in erster Linie gebraucht? was once hat ein Meteoriteneinschlag in Kanada mit Eisen und Nickel zu tun? Antworten zu diesen und vielen weiteren spannenden Fragen bietet dieses anschauliche Buch. Den Hauptteil bildet eine Einführung in die Lagerstättenkunde, in der nicht nur die wichtigsten Lagerstättentypen vorgestellt, sondern auch die grundlegenden Prozesse erklärt werden, die zu einer Anreicherung der jeweiligen Metalle geführt haben. Dabei geht es nicht nur um magmatische, hydrothermale oder sedimentäre Prozesse und um Verwitterung, sondern auch um den plattentektonischen Rahmen und um die Veränderungen in der Erdgeschichte. Im Kapitel zur fossilen Energie werden Erdöl und Erdgas ebenso behandelt wie unkonventionelle Quellen wie Schiefergas und das viel diskutierte Fracking. Wie am besten nach Lagerstätten gesucht wird, wie der Bergbau abläuft und wie aus dem Erz Metalle gewonnen werden, sind weitere Themen des Buches. Schließlich gehen die Autoren auch auf wirtschaftliche Aspekte ein wie die Entwicklung von Rohstoffpreisen und die Faktoren, die einen Abbau profitabel machen.

Over the final numerous many years, the variety of those who find themselves actively keen on the pastime or technological know-how of mineral accumulating has grown at an expanding velocity. in keeping with the growing to be call for for informa­ tion which this massive and energetic crew has created, a few books were released facing mineralogy. therefore, the reader now has a call between mineral locality publications, box handbooks, photograph collections, or books devoted to the systematic description of minerals. despite the fact that, as curiosity in mineralogy has grown, as creditors became more and more a professional and conscious of mineralogy in its many points, the necessity for extra really expert details has additionally grown. Nowhere is that this desire more than within the topic of the fluorescence of minerals. The variety of creditors who now major­ tain a fluorescent assortment is large, curiosity is consistently expanding, and brands have lately answered by way of the intro­ duction of recent ultraviolet apparatus with significant advancements in software and function. but whilst the collector searches for any info in this topic, little might be chanced on. she or he will search in useless for the solutions to questions which current themselves as in­ terest in fluorescent minerals grows and matures. Which minerals fluoresce? the place are fluorescent minerals chanced on? What makes a mineral fluoresce? Why does ultraviolet mild produce fluorescence? what's an activator, and the way does it give a contribution to fluorescence? On those concerns, the on hand mineralogy books are principally silent.

About The Product

Published through the yankee Geophysical Union as a part of the Short classes in Geology Series.

Our knowing of the mechanisms during which organisms shape minerals has stepped forward some time past 20 years yet continues to be at a rudimentary level. Any common concept of biomineralization needs to clarify the formation of stable stages from organic fluids in tenns of actual parameters equivalent to supersaturation, ionic power, pH, floor energies and the nature and volume of lively websites. wisdom of the services of the natural matrix in mediating mineral deposition is of simple value to any realizing of biomineralization.

The Ore Minerals and Their Intergrowths makes a speciality of the homes, features, and reactions of ore minerals.

The ebook first bargains details on genetic systematics of ore deposits and ore textures. Discussions concentrate on meteorites, magmatic, sedimentary, and metamorphic sequences, cloth houses thought of from a in simple terms geometric perspective, genetic cloth varieties, and the connection of ore textures with commercial minerals. The textual content then elaborates on annotation in regards to the association of fabrics and parts and intermetallic compounds.

The ebook takes a glance at alloy-like compounds and tellurides and customary sulfides and "sulfosalts". themes comprise umangite, bornite, jalpaite, argentite, naumannite, crookesite, coloradoite, novakite, orcelite, maucherite, parkerite, and horsfordite. The manuscript extra touches on oxide ore minerals and gangue minerals and non-opaque oxide ore minerals, together with quartz, calcite, dolomite, siderite, cerussite, smithsonite, jarosite, tenorite, zincite, and cuprite.

Most folks have heard of pyrite, the brassy yellow mineral generally known as fool's gold. yet regardless of being the most typical sulfide at the earth's floor, pyrite's vibrant crystals have attracted a noteworthy volume of cognizance from many various cultures, and its approximately exact visible visual appeal to gold has ended in stories of fraud, trickery, and claims of alchemy. Pyrite occupies a different position in human heritage: it turned an essential component of mining lore in the US throughout the nineteenth century, and it has a presence in old Sumerian texts, Greek philosophy, and medieval poetry, changing into an emblem for something overrated.

In Pyrite, geochemist and writer David Rickard blends easy technology and historic narrative to explain the various distinct methods pyrite makes appearances in our international. He follows pyrite again in the course of the medieval alchemists to the traditional Arab, chinese language, Indian, and Classical worlds, exhibiting why the mineral used to be critical to the improvement of those numerous historical cultures. Pyrite will be tracked to the beginnings of humankind, and Rickard unearths the way it contributed to the origins of our paintings and storytelling or even to our biologic improvement as people. yet pyrite has designated medical homes besides: the publication distills how oxidation makes fool's gold appear like a invaluable steel, and exhibits how pyrite can choke out oxygen from water, developing huge "dead zones" in our oceans. Rickard analyzes pyrite's function in production sulfuric acid, a compound used for every thing from cleansing drains to fertilizing plants. Its impact extends from human evolution and the formation of societies, via technological know-how and undefined, to our realizing of historic, sleek, and destiny earth environments. lively and obtainable, Pyrite is the 1st publication to teach readers the heritage and technological know-how of 1 of the world's so much attention-grabbing minerals.

This desire had arisen a result of specified houses of the samarium-neodymium isotopic method, and as the examine had transgressed the normal obstacles be­ tween the subfields of earth technological know-how. with out this sort of assessment, the importance of the consequences appeared more likely to stay un­ unavoidably vague to scientists from similar disciplines. hence, the second one target grew to become the supply of a theoretical framework for the applying of neodymium isotopic stories. a lot of what this includes isn't new, however it is drawn jointly the following for the 1st time. on the time the writing used to be initiated, the literature of the sphere was once nonetheless rather constrained. during the last five years it has grown greatly. contemplating the speed at which the writing stepped forward, it grew to become transparent that this couldn't be a completely up to date evaluation and nonetheless succeed in crowning glory. the choice of fabric for the assessment sections is biased towards prior reviews. half I provides many of the heritage information.
