Modeling Crustal Structures of Southern Nigeria Basins from Aeromagnetic Data: Implication on Hydrocarbon Prospectivity (Published)

Aeromagnetic data has been used by many authors worldwide in evaluation of subsurface basin configuration.This study covers parts of five basins (Niger Delta, Calabar Flank, Anambra Basin, Mamfe Basin, and Lower Benue Trough) in Nigeria.The study utilized twenty aeromagnetic maps on a scale of 1:100,000. The maps were digitized manually along flight lines and a total of 16,689 data points obtained. The data was processed using computer techniques including map merging,  reduction to pole, polynomial and power spectrum filtering for residual and regional anomaly separation,and forward and inverse 2.5D saki modeling .Results obtained from power spectrum depth analysis indicate depth to magnetic sources vis – a –vis sediment thickness  from the Niger delta area (2.75km -3.75km), Anambra basin (1.5 km – 2.6 km ), Calabar Flank (1.3 km – 2.3 km ), Mamfe basin (2.0 km – 3.4 km ), and Lower Benue Trough (1.5 km – 3.2 km ). Also,  depth to basement results from forward and inverse modeling indicate the Niger Delta has thickness of sediments ranging between 1.0 km- 8.0 km, Anambra basin (1.4 km – 2.7 km ),Calabar Flank (0.8 km- 2.5 km), Mamfe Basin (1.0 km – 2.7 km), and Lower Benue Trough (1.4 km – 2.7 km). Also, results from modeled number of intrusives indicate that the Calabar Flank has five intrusives , Niger Delta has four intrusives , Mamfe basin has six intrusives , Anambra basin has five intrusives, and Lower Benue Trough has four intrusives. The implications of the increased number of intrusives is that generated hydrocarbons might be converted to gas ,this is more likely in areas around Calabar Flank, Mamfe basin and Anambra basins, given the high number of occurrence of intusives within these areas. whereas  areas around the Niger Delta and Lower Benue Trough with significantly increased depth and lower number of intrusive are less proned to excessive heat from the intrusive and may produce more oil .The study support futher exploration activities within the Niger Delta and Lower Benue Trough areas.

CONFIGURATION OF NIGERIAN TERTIARY INSTITUTIONS EMPLOYEE USING MISSION STATEMENTS: A DISCOURSE (Published)

Organization Mission Statement is a critical roadmap or compass of an Institution. It is useful for practical day-to-day running of Institutions operation. However, significant percentage of Nigerian Tertiary Institutions employees is not adequately informed about the philosophy and objective of the institution which has affected their performance in the system. This qualitative study discusses the configuration of Nigerian tertiary institutions employee by using awareness, motivation and organizational commitment to spur Nigerian tertiary institutions for greater performance. Eclectic theory of social identity was adopted to position the study a distinct study. Results obtained revealed that there is presence of mission statement in Nigeria tertiary institutions; displayed on website, strategic places in the institutions. But significant percentage of the employees is not aware of their institutions mission statement despite the potentials it has to offer. The study concluded, given the mission statements are vital for dynamic management tool and advanced performance; it is outstanding that Nigerian tertiary institutions management should articulate mission statement, based on the environmental exigencies and where necessary make it collective responsibility among the employee in the institution.
