incorporated in the GIS,
including more than 27,000
deposits, in order to facilitate the
Production of thematic maps
showing provinces, belts and
Districts.

From the GIS two main products will be
generated:
1. The metallogenic map at 1:5.000.000
2. A deposits query system
Other derivated thematic products can be
generated like:
1. Metallogenic atlas
2. Thematic maps for specific deposit
types or tectonic environments
