An hypothesis is that carrying sand material and leaving silts. I strongly disagree with this theory because it can not justify the fine materials.
Maybe desert pavement is keeping humid stratas under that consolide unit.
Can you describe in more detail the profile that your referring to?
It may be formed (?) as a consequence of the Xerolysis process of weathering in arid zones. See papers of Chaussidon & Pédro (1968) and Chauvel & Pédro (1969).
finally i found best theory for desert pavement evolution.
fine material beneath the desert pavement are formed by aeolian deposition.

Yes. Javad. You have the point.
So called "Av horizon" which is a vesicular sublayer in A horizon.
This whole process relates to "floting pebbles supported by aeolian input".
You can find more in the most recent paper which I and my colleague published in ESR. "The life expectancy of a desert pavement"
