Most of the villages were not easily accessible but there were footpath leading to them. Journal of African Earth Science. Remember me on this computer. Deji Ogundana of Afe Babalola University Ado-Ekiti who actively participated in the field acquisition data and gathering of samples for this study. Between 14 — 18m along the traverse is a two layered geologic section.
The petrology of a composite syenite dyke in Igarra, Southwestern Nigeria. The second layer has a resistivity values in the range of ohm-m and can be observed reaching the subsurface 0- 15m at the western part of the traverse, a depth of 25m between 90 m of the traverse, and to a depth of 10 m between — m along the traverse. The process of bush burning is followed by hunting of bush animals by the indigenes. Authors contributions This work was carried out in collaboration between all authors. Before profiling is carried out, depth estimation of target may remain via electrical drilling or vertical electrical sounding VES , this is necessary for the determination of electrode spacing, the electrode array used for this profiling technique on the field which was mapped is wenner array.
IOSR Journal of began to acquire strain.
On the basement rocks of Bendel State of Nigeria. Archives of Current Research International 6 3: Prevalent brittle failures accompanied by viscous flow were responsible for the formation of the pinch and swell structures in the study area.
The rock from the two areas demonstrates a seemingly similar mineralogical composition. Generally, the lineations present in the rocks reciew in the study area are due to 1 Oriented growth of minerals.

Mineral assemblages in some veins are like those in the host kgarra rocks, suggesting formation during peak metamorphic conditions and possibly local interchange of material via a fluid into an open fissure. This structure was observed in the metaconglomerate were the quartz clast the competent bed within the metaconglomerate [location 6. Structural evaluation indicated that the rocks in both areas were strongly foliated with intense deformation.
Metaconglomerate is formed when conglomerate is subjected to metamorphism.
Time was taken off to study Sedimentary Formations which where located the study area Igarra. Veins offer convincing evidence for channelled flow of fluids through fractured rocks.

The Schist and Metaconglomerate occupy the lowlands and has an elevation of about m above sea level. Yamasaki Y, Ikeda T.
Metabreccia It is porphyroblastic and is fine to medium grain. This field exercise encompassed detailed mapping of the delineated area for efficient and detailed work of the area. Respiratory symptoms and ventilatory functions among Granite and schist which are in contact. This actually susbstantiate the fact that foliation and lineation planes are point of weakness which the stream capitalizes on.
Log In Sign Up. In this case, the vein is entirely made of quartz and it pre-date intrude the country rock granite.

The vegetation in this area is literatude secondary i. Establishing a solid mineral database for a part of Southwestern Nigeria. We were told the cause of failure of the dam initially it was constructed init was reconstructed in N — S see  shows literaturs there was a change 9. One characteristic feature common to all the clasts in the metaconglomerate outcrops is that their longer litrrature is aligned parallel to the direction of maximum stress strike direction.
The first type of folds F1 which where produced during D1 deformation is tight to isoclinals with folded axial plane. Outcrop 4 N The exposure consists of shales, clays, siltstones and sandstone. There is local quarrying of rocks such as granites and Quartzites for construction work by the inhabitants. The H values are From Fig.
It functions in global positioning, Navigation, communicator, compass, Altitude, Referencing, Planning of traverse, E. In geology of Nigeria [Kogbe igaera Revised edition ]. There is folding of the formation in a N-S direction Nwajide personal communication. Biotite Granite A flowing stream along the road which links to outcrop 1 stream, with N
