Structural distinction between a metasedimentary cover and an underlying basement in the 600-m.y.-old Pan-African domain of northwestern Nigeria, West Africa

“…These schist belts have been variously considered to be Archean in age (Russ, 1957), Kibaran (Ogezi, 1977; middle Proterozoic (Oyawoye, 1964(Oyawoye, , 1972 and Pan-Africa (McCurry, 1973). Grant (1978) and Turner (1983) suggested that there are two generations of schist belts, one Kibaran, the other Pan-African. The schist belts are considered critical to the understanding of the evolution of the Nigerian basement.…”

The North–South Paleozoic to Quaternary trend of alkaline magmatism from Niger–Nigeria to Cameroon: Complex interaction between hotspots and Precambrian faults

“…Else, it has been suggested that volcanoes in the offshore part of the CL are located at places where the CL crosses fracture zones (see Meyers et al, 1998, and references therein) while inland volcanoes are located along structures related to Riedel-style shear zones (Déruelle et al, 1991). Fold zones are characterized by Pan-African domes or diapirs of granitoid (calc-alkaline) rocks (Grant, 1978;Ngako, 1999). They determine broad areas bounded by the Nigerian and Cameroonian shear zones and are dominantly characterized by the occurrence of Paleozoic to Cenozoic ring complexes.…”

“…2) and extend westward into Benin and Togo. Component rocks are poorly dated, but most researchers are of the opinion that there were at least two and possibly three cycles (McCurry, 1971;Ogezi, 1977;Grant, 1978;Adekoya, 1996). The belts comprise a wide range of metasedimentary rocks including various pelitic schists and phyllites, quartzofeldspathic banded gneisses, quartzites, banded iron formation rocks and ferruginous quartzites, metaconglomerates, and dolomitic marbles and calc-silicate rocks.…”
