Geography of Ivory Coast southern region, especially the southwest, is covered with dense tropical moist forest. The Eastern Guinean forests extend from the Sassandra River across the south-central and southeast portion of Ivory Coast and east into Ghana, while the Western Guinean lowland forests extend west from the Sassandra River into Liberia and southeastern Guinea. The mountains of Dix-Huit Montagnes region, in the west of the country near the border with Guinea and Liberia, are home to the Guinean montane forests. The Guinean forest-savanna mosaic belt extends across the middle of the country from east to west, and is the transition zone between the
Geology of Liberia Geology of Liberia The geology of Liberia is largely extremely ancient rock formed between 3.5 billion and 541 million years ago in the Archean and the Neoproterozoic, with some rocks from the past 145 million years near the coast. The country has rich iron resources as well as some diamonds, gold and other minerals in ancient sediment formations weathered to higher concentrations by tropical rainfall. Two billion to 1.6 billion year old Archean and Paleoproterozoic underlie 90% of Liberia, forming the Man Shield, part of the West African Craton—a region of stable continental crust leftover from early continent formation.
