The Geomicrobiology of Ore Deposits
Economic Geology, 2005Bacterial metabolism, involving redox reactions with carbon, sulfur, and metals, appears to have been important since the dawn of life on Earth. In the Archean, anaerobic bacteria thrived before the Proterozoic oxidation of the atmosphere and the oceans, and these organisms continue to prosper in niches removed from molecular oxygen.

Το βιβλίο αυτό αναφέρεται στην καταγραφή των σημαντικότερων μεταλλοφόρων κοιτασμάτων της Ελλάδας και στις συνθήκες γένεσής τους σε σχέση με τη γεωτεκτονική εξέλιξη των Ελληνίδων. Έμφαση δίνεται στη γεωλογία, στην τεκτονική, στα πετρώματα ξενιστές και στην ορυκτολογική και γεωχημική σύσταση των κοιτασμάτων αυτών.

Abstract Three major categories of ore deposits—granite-related sensu stricto—were selected for detailed analysis: disseminated magmatic mineralization in granites themselves (rare metal granites); hydrothermal deposits, imprinted on the granites and their immediate vicinity (vein and greisen type); and late-magmatic pegmatites ...

Reviews of Geophysics, 1995
Metallic ore deposits constitute the largest geochemical anomalies within the crust. Their study has been critical to understanding the behavior of elements and isotopes in mineral‐ and rock‐ forming processes, as well as to deciphering the geochemical differentiation of the Earth through time.

Ore Deposits of the Central Andes
Elements, 2018The Central Andes has one of the richest base metal endowments on Earth. In 2017, the Central Andes accounted for the mine production of around 39% of the world’s copper, 23% of its silver, 20% of its molybdenum, 14% of its zinc, and 12% of its tin as well as significant shares of other metals including gold and lead (USGS 2018). These metals are found

The relationship of layered igneous intrusions and associated magmatic ore deposits to mantle plumes is discussed in the preceding chapters. Models of environments and geometries linking mantle plumes to magma chambers and high level intrusions are illustrated in Figs. 2.10, 2.11 and 3.22.

Palaeomagnetism and Ore Deposits
1974Das Vorkommen von Erzlagerstatten in Zusammenhang mit Bewegungen von Kontinenten (oder Platten) mus von zwei Gesichtspunkten betrachtet werden. Der einfachste Fall ist dort gegeben, wo bestehende Lagerstattenprovinzen aufgespalten und die Teile in verschiedenen Kontinenten separiert werden wie z. B.
