features

Serire are areas in the central Sahara, mostly in the vicinity of mountains as an area that is covered with uniform pebbles . According to the size of the stones, serires are divided into coarse (6 to 60 mm) or fine serir (2 to 6 mm). The Serir Desert has a share of 10% of the area of ​​the Sahara. They mostly appear as desert patches, probably created by deflation.

Emergence

Serires arise when, for example, the conglomeratic rock cover weathered, the fine material is removed and the pebbles remain in place. They can be relocated by water or attacked by wind, which leads to shaping (rounding) and smoothing. Another common factor is salt blast .
