Organic Matter and its Significance for the Genesis of the Copper-Bearing Shales (Kupferschiefer) from the Fore-Sudetic Monocline (Poland)
Geochemical data for the organic matter (OM) in the Fore-Sudetic copper-bearing shales have been collected and evaluated. They were also compared... -
Konkola Deep Mining Project: Concept and planning
It is the hope of the authors that this paper would at least partially fulfil its purpose of making the reader aware of the conceptual planning...

On the Association of Ore Deposits with Stromatolites
Several stratiform ore deposits show the following characteristics: (1) close association with stromatolites; (2) occurrence along the borders of a... -
Hydrothermal Mineral Deposits of Continental Rift Environments
In Chapter 6 (Sect. 6.2.2) we introduced the subject of continental rifts and aulacogens, and their related mineral deposits. In this chapter, we... -
Lead isotopic signatures at the Klein Aub Mine, Namibia — Implications for mineralisation models
Pb and U isotopic data have been obtained for stratabound, sediment-hosted Cu-mineralisation and igneous, volcanic and sedimentary rocks from other...

Geological Processes and Hydrothermal Mineralisation in Plate Tectonic Settings — Mineral Exploration
The Earth’s outer layers, namely, the lithosphere and the asthenosphere have an important role in the mechanisms of plate tectonics. The outermost... -
Geotectonic and Metallogenic Analysis of Orogenic Belts
In this chapter we discuss the geotectonic and metallogenic analysis of the Late Proterozoic Pan-African orogenic belts of Africa, and the... -
Hydrothermal Systems
In this chapter the types of hydrothermal activities and systems responsible for the genesis of a wide range of mineral deposits are described.... -
Crustal Evolution, Global Tectonics and Mineral Deposits
The theory of sea-floor spreading and the “new” global tectonics, including the more recent ideas on accretionary tectonics, has permitted a much... -
Mineral Deposits and Metallogeny: Indicators of Earth’s Evolution
Major types of mineral deposits exhibit distinct changes in composition and geological setting from Archean to Recent time. These changes include... -
The origin and economic potential of sandstone-hosted disseminated Pb-Zn mineralization in pyritic shale horizons of the Mid-Proterozoic Newland Formation, Montana, USA
Pyritic shale horizons of the Newland Formation (Belt Series, Mid-Proterozoic) show striking similarities to Proterozoic pyritic shales elsewhere...
