The location is located along Akwanga
– Wamba road and the outcrops is called Agbonju hill. It is an outcrop that
summarizes all the basement complexes. The components of these units are
gneiss, migmatite, granite gneiss, aplite and pegmatite.
Quartz–feldspar
which occurs as veinlet/veins and basaltic dyke are seen here. Others are
faults, folds, joints, and foliation. The mineral compositions are felsic
minerals, like quartz, feldspar and mafic minerals like biotite.
The
measurements taken here are as follows
Trend of basaltic dyke
N349o - N168o
Thickness of basaltic dyke
24 – 30cm
Dip amount of the dyke – 21o
Direction of dyke
N282 – N101
The composition of the dyke are small
amount of quartz and abundant of mafic minerals like biotite, plagioclase
