What is the geology of Zambia?

Zambia is effectively sandwiched between the Kasai, Zimbabwe - Kaapvall and Tanzania cratons.

The oldest succession of rocks in the country (c.3000 Ma.- 2050 Ma.), the basement supergroup, consists mostly of granitic gneissis and migmatites, found throughout eastern, central and southern Zambia.

Overlying these basement rocks and generally exhibiting an infolded, imbricate and tectonized contact with the basement sequence are a series of younger sedimentary sequences; the Muva Supergroup, the Mporokoso Group and the Kasama Formation which form part of the regional Irumide and Zambezi oragenic Belts.
