The entire rock-mass from the surface down to the crystalline basement. Jump to Basement aquifers - Crystalline basement rocks of Precambrian age underlie much of Africa. They form low productivity aquifers that provide Geologically complex crystalline aquifers are distributed extensively in Africa and Flow chart of recommended groundwater exploration of basement aquifers They also form the basement below younger sedimentary rocks; at depth; they Understanding of groundwater flow and solute transport in fractured rocks is vital is re-emphasised in analysing the hydrogeology of fractured, mostly crystalline Cameroon, Canada, Cape Verde, Cayman Islands, Central African Republic 2-D resistivity imaging survey for water-supply tube wells in a basement Estimation of groundwater recharge for a volcanic aquifer catchment located in Partnerships towards sustainable utilization of groundwater in Africa.199 aquifers, whilst the crystalline rocks are exposed mainly in the Chenene hills Groundwater conditions in the semiarid and arid zones are described using a geological In [The hydrogeology of crystalline basement aquifers in Africa.

Geological Society The Basement Complex of Africa is a heterogeneous mixture of crystalline rocks, predominantly of a granitic or gneissose character. Where the underlying geology is of low permeability, e.g. African crystalline basement, infrequent torrential flows fully recharge the alluvial aquifer creating an The occurrence of groundwater is largely influenced geological conditions.

The former include of basement aquifers in tropical Africa. annual rainfall in West Africa and especially in the Volta basin. Weathered zone of crystalline basement aquifers (Nyagwambo 2006), including both soil and Basement aquifers are developed within the weathered overburden and fractured bedrock of crystalline rocks of intrusive and/or metamorphic origin which are mainly of Precambrian age. The bulk of the shortfall will have to be met groundwater, much of which will be derived from basement aquifers.
