Most of the geology of northern Guyana consists of Palaeoproterozoic Orosirian greenstone belts (Barama-Mazaruni Supergroup) intruded by granites. These are overlain unconformably by the Statherian Burro-Burro Group, which consist of the Muruwa Formation sandstones and Iwokrama Formation felsic volcanics.

The geology of the North Rupununi is critical because it fundamentally defines the topography, soils, hydrology and ultimately the economy of the area. The North Rupununi is part of a Mesozoic graben, the Takutu Basin. The basin is 280 kilometers long and 40 kilometers wide, is over 7 kilometers deep, and covers more than 11,200 square ...
The geology of this area is divided into four main zones. Furthest south are areas of Rhyacian meta-sediments, meta-volcanics (Kwitaro Group) and associated granites, all intruded by Orosirian rocks of the Southern Guyana Granite Complex. The Kanuku Mountains consist of high grade gneisses in a NE-SW belt.
Mount Roraima is located in the northern part of South America, the Pacarema Mountains in the eastern part of the Guyana Plateau, Brazil in the east accounting for 5% of its area, Guyana in the north accounting for 10%, and Venezuela in the south and west accounting for 85%.
Guyana's tropical climate, unique geology, and relatively undisturbed ecosystems support extensive areas of species-rich rain forests and natural habitats with high levels of endemism. There are about 8000 species of plants in Guyana, half of which are found nowhere else.
