The Geology of Ibodi Area, Ilesha
THE GEOLOGY OF IBODI AREA, ILESHA.
REPORT ON THE INDEPENDENCE GEOLOGICAL FIELD MAPPING AT ILESHA, OSUN STATE
SUBMITTED TO THE DEPARTMENT OF GEOLOGICAL SCIENCES, OSUN STATE UNIVERSITY, OSOGBO.
July 2013
CHAPTER ONE: INTRODUCTION
1.1 LOCATION OF THE MAPPED AREA
The mapped area is located in Ilesha Atakunmosa local government area of Osun State, Nigeria.
The area mapped lies approximately within latitudes 7° 34' and 7° 37' north and equally lies approximately within 4° 39' and 4° 42' west, and covers an area extent of about 30km².
1.2 ACCESSIBILITY AND NATURE OF EXPOSURE
The study area can be accessed through the old road from Osogbo and also through the new road from Osu or Ife, both roads and footpaths were used during the mapping exercise.
Rocks were not well exposed, most of which were covered by either soil or vegetation. And are also affected by weathering
1.3 OBJECTIVES
The exercise was done by 300 level students which were grouped into five groups with three students in each group to carry out the mapping exercise in different parts of Ilesha local government, Osun State, Nigeria.
The field exercise is also one of the requirements to be fulfilled for the bachelor degree of science, in the department of geology of Osun State University, Nigeria. The field mapping exercise lasted for 14 days.
At the end of the mapping exercise the geology of the study area should be known and an accurate geological map of the study area should be made.

1.4 METHODS OF INVESTIGATION
The mapping field exercise was done by road and footpath traverse using the topographical base map of the area which has a scale 1:25,000, the base map contains details of the study area and observations made during the mapping exercise were plotted on it. A global positioning system (GPS) was also for accurate location of outcrops on the base map. A geological hammer was used in collecting samples of every outcrop
