✦ Synopsis
Investigations of ore deposits within the West African Craton and surrounding areas
This volume presents a series of papers dealing with ore deposit investigations within the West African Craton and the surrounding areas. This collection of 14 research papers arose from keynote, guest and volunteer presentations given at meetings of the International Geological Correlation Program (IGCP) projects 485 1 , 502 2 and Workshop on the Geology and Metallogenesis of the Hoggar and Eglab massifs held in Tamanrasset (Algeria) on March 1-3, 2005.
The ore deposit research activity is increasing nowadays owing to the recent demand for metallic ore in different areas, mainly electronics, health, industry and agriculture and owing to the rising prices of specific metals such as PGE (e.g. Maier, 2005). The use of modern tools of investigation in the field as well as in the laboratory has greatly improved the understanding of the ore deposit mechanisms and their interpretation, since the fields of research for such investigations concern as wide a range as sedimentology, stratigraphy, metamorphic petrology, tectonics, structural geology, geochemistry, geochronology, metallogenesis, gravity and magnetics. This volume will be of interest to all those involved in research or mineral exploration concerned with the above tools of investigation. Several special issues were published in the past suggesting a great interest in the timing of formation of the metallic ore deposits (e.g. Blundell et al., 2002). Ore deposits provide new evidence for magmatism associated with Cratons or Metacratons and their boundaries where major fractures or shear-zones exist, through which fluid circulations and alterations may occur. Hydrothermal fluids can be at the origin of mineralizations such as oxide, sulfide or PGE ore deposits (e.g. Mile ´si et al., 2006; Jefferson and Delaney, 2007). What controls the genesis of ore deposits in ''stable" areas such as the West African Craton, what are the geodynamic and the metamorphic processes which
