The aim (reasons) of this field trip work is to
expose student to practical aspect of geology such as knowing the lithological,
structure and complex nature of Nigeria
basement rocks to enable them relate the field experience with theoretical work
for easy understanding and interpretation. It also aid student the opportunity
to interact with different ethnic groups. It impacts into student the knowledge
on how to use geological equipment like compass, G.P.S, and others.
1.7 METHODOLOGY
This involves visiting the outcrop as well as locating ourselves in
the base map, interpreting the features of the rocks such as textures, mineral
composition, colour, structures and as well taking the photograph where need
arise.
1.8 INSTRUMENT
USED
For the trip to be fulfilled certain instruments are needed, such
as:
(i)
The base map: The map also
known as topographic map is used to locate an outcrop or any other physical
features of geologic importance which is in the map. It serves as a guild for
the journey.
(ii)
The compass: The compass is
useful in taking measurement. It has its primary component, a magnetic needle
with sharp pointed suspension used for the measurement of direction with
respect to cardinal points NS – EW. It also contain the clinometers used for
end is blunt and the other end is ebisel which is use to scoop out samples from
loosed materials and the blunt end for knocking out samples from hard compact
mass of the outcrops.
(iii)
Field note book, pen and
pencil: They are used for taking records of the observation in the field. These
include the description of the rocks, the area the outcrop is situated and the
measurement of structures associated with the outcrops.
(iv)
Sample bag: For collection of
samples for laboratory investigation.
(v)
Masking tape and marker: They
are used for labeling of samples.
(vi)
Hand lens: It is used for
macro-visualization of tiny or minute rock units such as fine to very fine
grained size.
(vii)
Camera: It is used for taking
photographs of outcrops and structures available.
