Abstract
[Abstract] The Andringirra Massif is a srratoide granite on the south of the Isle of Madagascar. Is a residual reliefwhich represents one ofthe last remnants of the Gondwana surface at the island egraded after the break of the supercontinent.Three different levels at 2500m, 2000m and 1500m of altitude with the etche forms associated show different stages at the evolution of the massif. Over these pediments was preserved different kinds of granite etche forms at different stages ofevolution with a very clear relation with the surface age younger fram the top to the bottom of the massif. After the exposure of the etched relief, the corresponding forms evolves suabaerially which signify that they shows two stages of evolution: one subedaphical the other subaerial.
