Ica is a region in Peru. It borders the Pacific Ocean on the west; the Lima Region on the north; the Huancavelica and Ayacucho regions on the east; and the Arequipa Region on the south. Its capital is the city of Ica.
The Ica Region has a remarkable geography. It is the only region of the southern coast formed by plains, also called coastal plains, since the Andean Cordillera rise up inland. Some geological folds have determined the formation of dunes moving toward the sea, which form much of the Paracas Peninsula. Some isolated formations located at the southern part created the Marcona complex, with the biggest deposits of iron in the Pacific coast.
