Guinean Forests of West Africa Guinean Forests of West Africa The Guinean forests of West Africa is a biodiversity hotspot designated by Conservation International, which includes the belt of tropical moist broadleaf forests along the coast of West Africa, running from Sierra Leone and Guinea in the west to the Sanaga River of Cameroon in the east. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Guinean forests into the Upper Guinean forests and Lower Guinean forests. The Upper Guinean forests extend from Sierra Leone and Guinea in the west through Liberia, Côte d'Ivoire, and Ghana to Togo
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.
