Pr. Michel Petit explained the orogenesis of the precambrian bed rock of the Highlands This was done in front of the perched synclinal called "Casque de Behenjy" (Behenjy Cap). This is a complex substratum in which migmatites, gneiss and micaschists alternate, and which presents ectinic characters The ectinites are well preserved in a beautiful disymetric perched synclinal, owing to a beautiful blade of a concordant migmatic granite The Malagasy name is Iharanandriana which means "The nobles's rock barrier". This structural accident contains the tombs of the princes of the region on its summit.
