Geology of a wide-ranging country

The general geology of the country Basari (Senegal, Western Africa) is modeled by an alternation of the complex metamorphic and plutonic. It has got a plane with the general geology of Senegal. Glaringly, this basic configuration is finished at local level on these complicated effects of the continuing processes of erosion and sedimentation, the results can be seen on the surface of the area.

In a short visit can be confirmed that setting and observe further details. In the cascade of Dindifelo, possibly due to a fault, affirms the huge presence of quartzite round his forehead. The climb to the waterfall is developed by a stream in the foothills formations, naturally thicker as you approach that.

At the crest crowns a rocky formed very dark. An Internet webscan can show us that it is similar to those of Guadarrama (Spain), while the increase is across a stretch in which outcrops of slate appreciated.

Beaches of from granitic rocks and quartzite

Moreover, in both locations the soil was usually sandy and rocks haven't been detected, except in a few localized spots, doubtless clay items have been washed away. The sandy nature was logical to locate both in plains at the foot of rocks of granitic and quartzite which, as it decomposes, creating the sand noted. A very small depth of the sand appears to be crusts, by cementing a normal activity (perhaps by wetting and drying).

As is understood, metamorphic and plutonic rocks aren't conducive to groundwater, particularly the second, while the sand is a good material for the manipulation of groundwater, storage capacity and water movement.

The depth of water table in Bandafasi (about 5 – 6 meters measured in 2 distant wells) may be related to these scabs or topography, as there seemed to be declining across the road. On the ground was waterlogged Dindifelo and appreciate input streams of water to carry away from inside the channel.
