Mauritania: A Greenfields Exploration Opportunity in Northwestern Africa (Continued)<br />
Corporation was reported to have discovered<br />
a potential kimberlite area in<br />
the Tasiast-Tijirit terrane. Gunn et al.<br />
(2004, based on Rombouts, 2003) states<br />
there are two kimberlite provinces on a<br />
NNE-trending lineament within the<br />
Taoudeni basin that also localizes the<br />
Guelb er Richat and Semsiyat domal<br />
features thought to be carbonatite<br />
intrusions at depth. The western cluster<br />
is located near the Guelb er Richat<br />
dome. The poorly located eastern cluster<br />
contains 21 kimberlites, <strong>of</strong> which 7<br />
are diamondiferous (Rombouts, 2003).<br />
CONCLUSIONS<br />
As a result <strong>of</strong> the aggressive development<br />
<strong>of</strong> the exploration and mining sectors <strong>of</strong><br />
the economy by the Mauritanian government<br />
through programs <strong>of</strong> data<br />
acquisition and synthesis such as those<br />
described above, Mauritania now can<br />
provide a greenfields exploration opportunity<br />
supported by a wealth <strong>of</strong> readily<br />
usable state <strong>of</strong> the art geoinformation.<br />
Additionally, the presence <strong>of</strong> geological<br />
environments that include Archean craton,<br />
Paleoproterozoic metasedimentary<br />
belts, Pan African orogenic belts, and<br />
major cratonic and coastal sedimentary<br />
basins, as well as the presence <strong>of</strong> several<br />
world-class ore deposits, should get the<br />
attention <strong>of</strong> any explorationist. We have<br />
summarized some <strong>of</strong> the more exciting<br />
potential areas for gold, IOCG, iron,<br />
uranium, gypsum, phosphate, REEs, critical<br />
metals, and diamonds in Mauritania.<br />
But we have not even touched on the<br />
more speculative potential for sedimentary<br />
rock-hosted base metals, VMS,<br />
shoreline placer titanium, or a variety <strong>of</strong><br />
industrial minerals that, owing to their<br />
proximity to the Zouerate-Nouadihbou<br />
railway, may represent additional economically<br />
viable commodities. The raw<br />
data packages are available through the<br />
Ministry <strong>of</strong> Petroleum, Energy, and<br />
Mines in Nouakchott. The derivative<br />
maps and reports described will soon<br />
be available on the USGS Mineral<br />
Resources Program website (accessible<br />
at: http://minerals.usgs.gov/).<br />
