PRISM products
One of the subjects in the PRISM project is to establish and update a geological information infrastructure and to supply geological and geophysical information for private investment sector. The followings are main components for creation of the database;

Geological mapping
Establishment of SIGM, geological and mining information system, and supply of available products
for potential investors
Data acquisition by airborne-geophysical survey

Geological mapping is to establish geological maps with the scale of 1/500,000 covering the entire country and to create geological maps of 1/200,000 covering 54 sheets in 108 sheets of the whole territory. The creation of 1/500,000 maps was already completed and was stored in the SIGM database. 32 sheets of 1/200,000 geological maps have completed, 14 sheets are in processed and 8 sheets are planned as of February 2005.
Geo-chemical sampling has been made during geological survey and more than 25,000 analyzed data will be obtained finally.

The SIGM database comprises various kind of dataset, topographical maps, country and administrative boundaries (Wilaya, Moumata), cities, villages, rivers, infrastructure like road and railway, geology, mineral occurrences, satellite imagery data, airborne geophysical data, concession areas, elevations (points and contours), which are stored in ArcView. Furthermore, a lot of bibliography is stored in the Adobe PDF file format. To date, a wide range of information of including loading of databases, maps and bibliographic data has been integrated into the system.
Products from the on-going PRISM projects are entered into the system, and some of them, for instance, geological maps, geochemical and geophysical data and hydro-geological maps, are available to supply for foreign investors and institutions (

Airborne geophysical survey is an essential and indispensable exploration tool for countries like Mauritania whose surface is widely covered by sand desert. In the PRISM project, Mauritanian territory is divided into the following six zones, and airborne geophysical surveys, airborne magnetic and radiometric methods, have been carried out in the highest priority areas, the northern Mauritania zone (Dorsal Reguibat Shield area), and the southern zone (near boundary with Mali). The results will be entered in to SIGM database in this year.
