This paper analyses remotely sensed data over a part of the Psammitic Rocks in Efon-Alaaye and Environs to elucidate its geology and structural framework as well as delineate the potential zones of mineralization. The study area belongs to the Precambrian Basement Complex terrain of Southwestern Nigeria and lies within the eastern unit of the Ilesha schist belt. The lithologic units comprise schistose quartzites, quartz schists, quartz-mica-schists, and granitic gneisses. Landsat 8 satellite imagery and Shuttle Radar Topography Mission imagery (SRTM), both of path 190 and row 055, were used for the purpose of this study. A total of 138 lineaments of total length of 147.948 Km, were automatically extracted from both data. Rose diagram showed that the lineaments are bi-directional, with major lineaments trending NE-SW, E-W and the subsidiary ones in the NW-SE direction. These lineaments are mostly mapped on the schistose quartzites. Also, N-S trending faults were mapped from the Digital Elevation Model map generated from the SRTM data which was confirmed to be reverse fault based on field studies. The mineral alteration map generated revealed signatures of gold, iron oxides and silica minerals, while the mineralization potential map was done with reference to established geological settings of the area in conjunction with the structural elements such as folds, faults, joints and fractures mapped and measured on the field. These structures are typical of gold mineralization and associated metallic minerals in the Ilesha schist belt. This study also confirmed that mineralization in the study area is structurally controlled and type of mineralization is epigenetic in nature as a result of favorable ground preparation.

The aim of the study is to access the economic implication of absence of National carrier in the Nigeria aviation industry. The airline industry is the key drive of the travel and tourism industry and also a major contributor to many countries’ overall economy through international tourist arrivals and departures. The study estimate the amount of revenue Nigeria is losing to capital flights for not having a viable national carrier over the past ten years that is from 2007 to 2016.The estimated amount of revenue loss was examined on airlines offering direct flights on Nigeria to London route, in which we have two foreign airlines (British airways and Virgin Atlantic airline)and a Nigeria’s private national carrier which is Med-view airline. The class of tickets and services in each class of ticket being offered by the airlines was examined. The study reveals an estimate of total of over $6 Billion revenue were being lost to hands of foreign competitors over the past ten years with British airways generating closely to $4 billion, while Virgin Atlantic generated over $2.3 billion and Med-view generated over $133 million in the past ten years. The study also reveals that the higher the passenger carried the higher the revenue and vice versa. However, establishing a national carrier by the federal government is imminent which will express Nigeria culture and to better serve passengers especially Nigerians. Finally, banks and other governmental financial institutions should make available enough funds with longer payback period and little interest for both existing airlines to upgrade their services and new entrants to be able to purchase necessary equipment’s to make them competitive in the market.
