The geology of Africa is varied and complex, and gives rise to the wide variety of landscapes found across the continent. The African continent rests over two main plates. The African Plate , accounting for the whole of north Africa, and the Somali Plate , which accounts for the eastern side of mid and southern Africa. [ 1 ]
In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...
Geologic map of South Sudan The geology of South Sudan is founded on Precambrian igneous and metamorphic rocks , that cover 40 percent of the country's surface and underlie other rock units. The region was affected by the Pan-African orogeny in the Neoproterozoic and extensional tectonics in the Mesozoic that deposited very thick oil-bearing ...
The geology of Central African Republic (CAR) is part of the broader geology of Africa. CAR occupies a swath of ancient rocks, dating back billions of years that record significant aspects of Earth history and yield minerals vital to the country's small economy.
The country is famous for its mineral deposits of Tsumeb, as well as many geological sites of interest, from paleontological, geomorphological and volcanic character. Due to the exposure of the formations in a desert climate and the former German colony, the geology of Namibia is relatively well studied compared to the more tropical less ...
Natural gas is found offshore of Port Sudan in the Red Sea, and many mineral reserves are situated in the eastern highlands. Sudan has chromite , gold , gypsum , limestone , and salt , although the combined production of chromite, salt, and gold accounts for only one percent of the value of exports .
A significant portion of Rwanda's economy is based on mineral extraction. Rwanda is the foremost producer of tungsten in Africa, producing 70% of Africa's total output. Rwanda is Africa's second highest producer of tin and coltan, accounting for 20% and 30% of the country's output, respectively. Rwanda also produces 9% of the world's tantalum.
