Abstract
Itatim geomorphological site (IGS) in central-eastern Brazil is prominent among inselberg terrains worldwide due to the quantity and variety of shapes (castles, bornhardts , inselgebergs, castle koppies, and tors), formed from the Miocene. Factors that have played a role in the origin of Itatim inselbergs include: (i) the presence of younger intrusions within an ancient bedrock; (ii) location in shear and other tectonic contact zones where high- and low-strain areas are juxtaposed; (iii) mineralogical differences between the inselbergs and the surrounding rocks; (iv) regional uplift followed by tectonic stability in the past tens of millions of years; and (v) arid and semiarid climates exerting influence in the most recent geological past into the present.
