Accompanying these movements were great expansions of granitic magma and prolonged secondary erosion, resulting in sedimentary cliffs and unaccented mountain ranges. A tertiary phase, in the raised areas, resulted in fractures in the dominant northeast-southwest axis, resulting in a variation in relief caused by different rock resistance.

The variation in slope allows for a diverse microclimate, with different vegetation between high and low altitudes. The combination of microclimatic conditions and rainfall has resulted in a lush landscape.
