AIMS AND OBJECT OF RESEARCHING ABOUT NASSARAWA STATE

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.
