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.

Covering an average distance of some 1,120 km from south to north, Nigeria displays physiographic regions of varying characters in relief, nature and spatial distribution. These attributes of the physiographic regions correspond to the occurrence of the three classes of rocks, namely, the igneous, metamorphic and sedimentary rocks.

The basement complex rocks are essentially granites, gneisses, migmatites, schists and quartzites (Benett, 1979;13). The geology of Kaduna North is predominantly metamorphic rocks of the Nigerian basement complex consisting of biotite gneisses and older granites (Kaduna State, 2003).

Metamorphic Rocks in Britain. The oldest rocks in Britain are found in NW Scotland and the western isles. This ancient Lewisian gneiss is almost 3,000 million years old! The Scottish Highlands are mainly formed from metamorphic rocks formed around 400450 million years ago. Ben A'an shows foliated micaschists exposed at the top.
