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 />
