Historically, the rock was used as a defensive retreat by the Gbagyi people against invading neighbouring tribes during intertribal warring. It is 3,691 feet in height which makes it talled than Aso Rock and Olumo Rock put together. Wase Rock. Loed in Plateau State, Wase Rock is one of the few volcanic rocks in Nigeria.
INTRODUCTION. Charnockitic rocks generally have diverse origins, spanning a range of metamorphic and igneous derivations (Kilpatrick and Ellis, 1992) which implies that igneous or metamorphic fabric can be Nigeria, charnockitic rocks constitute one of the major petrologic units of the precambrian basement complex (Olarewaju, 2006).The charnockitic rocks of Akure area form a part ...
2 CHAPTER TWO GEOLOGY OF NIGERIA ROCK TYPES The three major rock types igneous, metamorphic and sedimentary abound in Nigeria. Igneous and metamorphic rocks constitute the Precambrian basement complex which is the oldest, crystalline, solid physical foundation of the country.
· Kufena Hills is loed in Zaria, Kaduna State, northern Nigeria. Kufena hills is made up of metamorphic rocks which form the base material at the core of the earth's major continental masses. The landscape's diverse ecosystem, flora and fauna and various landforms make the hills and its environs outstanding.
· Metamorphic rocks of the BossangoaBossembélé area in the northern Central African Republic (CAR) consist of both metasedimentary and metaigneous units. A petrographic investigation reveals that the metasedimentary unit is composed of pelitic granulites while metaigneous unit comprises mafic granulites. The mineral assemblages are indiive of granulite facies conditions (, .
In the upper part of the Benue Trough of Nigeria, several major NE–SW lineaments are essential components in the structure of both the PanAfrican basement and the Cretaceous sediments. In order to estimate their influence on the geodynamics of the Trough, detailed structural analyses have been carried out on the fault rocks of one of them ...
Over 50% of northern Nigeria is covered by both the rocks of the basement complex rock types and the sedi mentary rocks (Figure 1). The Older Granites, migmatite and gneissic rocks comprise the extensive mass of metamorphic rocks un derlying most areas of the north and west of the country. The rocks include different textures of granites ...
The Basement complex of Nigeria is polycyclic and retains memories of events dating back to about 3000 m. y. As in other parts of Africa, it suffered its most pronounced deformation and remobilisation during the Pan African Orogeny (about 650450 m. y. ago). A review of the geology of this terrain is presented following recent field and geochronological data.
being part of the central Nigeria highlands and Jos Plateau complex. However, two broad relief zones can be identified, as follows:a) A western high land area of hill ranges, including the northern edges of the Jos Plateau complex. This is part of the crystalline rock area in central northern Nigeria.
The Basement Complex rocks consist mostly of igneous and metamorphic rocks with relatively shallow weathered mantle that permits very limited groundwater content. On the other hand, the Chad ...

Metamorphism in the southwestern Nigeria basement rocks On the basis of petrology a medium pressure Barrovian and Lowmedium pressure types of metamorphism had been suggested for the Precambrian basement rocks in south western Nigeria (Rahaman 1988). These metamorphic types are based on the occurrence of index
Stratigraphy, Tectonics Geologic History. The oldest Precambrian rocks in Nigeria likely formed during the Archean or the Paleoproterozoic, forming the Beninian gneiss, in the BeninNigeria Orogen, formed during the Proterozoic PanAfrican crystalline basement rock of the country is grouped as the Nigerian Province, a southern continuation of the central Hoggar reactivated basement.
