A Literature review on the Geology and Mineral Industry of Sierra Leone
Geologic Country Report with Emphasis on Diamonds, Gold, and Titanium (July 2011)
The Republic of Sierra Leone is located on the West Coast of Africa, between latitudes 7 and 10 north and longitudes 10.5 and 13 west.
The mining sector is a significant contributor to Sierra Leone’s economy; it accounted for about 90 % of export revenues, mainly from diamond exports, and 20 % of the gross domestic product (GDP).

Geochemical composition of sedimentary rocks and imprint of hydrothermal fluid flow at the Variscan front – an example from the RWTH-1 well (Germany)
The mineralogical and chemical characteristics of Palaeozoic rocks in the northern Eifel Mountains provide information on the sedimentary provenance in the NW Rhenohercynian Basin and on the mineralogical and hydrothermal control of trace element abundance. Elements mainly bound to illite (i.e. V, Ni, Rb, Sr, Cu, Ba) can be distinguished from elements predominantly controlled by chromite (Cr) and zircon (Zr). Lower Devonian and Upper Carboniferous units have similar (more…)
