ECONOMIC GEOLOGY
Economic geology deals with
the various economic deposits in our environment. In the course of the field
mapping, some economic rock deposits were discovered in the study area, some of
which were already being exploited. Some of these economic rocks are excavated
and used in road construction and locally in construction of mud houses which
are common in the villages. Some of these economic rock deposits include the
following:
Pyroclastics
In the study area, there are
outcrops of pyrodastics which is as a source of raw materials for construction
of roads, house, bridges and culverts etc.
People living in
the villages around the quarries are employed to work and they are paid daily.
Thus, the presence of this economic rock deposit has provided job employment
for the inhabitants.
Shales And Laterites
Laterites in the study area
form as a result of chemical weathering (oxidation). laterites are excavated
and used in road construction and also in construction of mud houses.
Shales is the most
common in the study area. The indurated shales are quarried and used also in
constructions. While the fissile shales are used in constructing mud houses.
NOTE: Shale is mainly of a geological significance thus,
geologically, shale not only serves as trap for hydrocarbon but also it helps
in the preservation of fossil e.g Ammonites. Also shale help in the development
of springs wherever its contact with permeable sandstone becomes exposed to the
surface.
