Abstract: The Edea and Eseka area belongs to the Nyong Series which is the north-western extension of the Congo Craton in Cameroon. Structural analyses were carried out in this region in order to delineate the tectonic evolution. The structures of this area are the result of a complex structural evolution and the area experienced a polyphase deformation resulting to a succession of several phases of deformation. Detailed information on the structures and the relative timing of deformation are as follows: (1) an early stage (pre- D1) phase corresponds to the relicts of an early schistosity preserved as inclusion trails in garnet and pyroxene crystals, immediately followed by (2) two main stages (D1 and D2). D1 evolved in tangential movements, it is typically ductile and characterized by a.......

Abstract: The research of massive rock extraction site (granite) to Gbamakro (Central Côte d'Ivoire) requires a good knowledge of the subsoil. This requires the implementation of geophysical methods of resistivity (profiling, sounding and electrical tomography). The aim is to determine the lithological and structural characteristics of the study area subsoil. The results show a resistant granite massif with fractures oriented N70 to N120. At north of the site, the fractures are associated with an altered massif. The roof of the massif is located under an altered horizon less than 5 m thick. Except north of the site, where it is at a greater depth (16 m).

Abstract: Stable isotopes are very useful to trace groundwater from their recharge origin as precipitation. This is due to the conservation of the meteoric signal during its subsurface flow. Thus, is very important to have a local meteoric line (LML) in every world region to more accurately adjust the interpretations of hydrological relationships and processes like recharge areas, evaporation, water mixtures and probable isotopic exchanges with rocks and sediments. The objective of this work is to analyze the isotopic composition of precipitations in the dry sub-humid sector of the Pampa plain of Córdoba, its connection with the meteorological conditions and the temporal variations to improve..........

Abstract: The study investigated the level of heavy metals in surface waters and sediments in the Lagos Lagoon, Lagos State. Water and sediment samples were collected in sterile plastic containers respectively from 8 sampling locations inclusive of a control. The samples were treated and digested and analyzed using the Atomic Absorption Spectrophotometer (AAS).The t-test, single factor ANOVA, post-hoc means plot and Principal Components Analysis (PCA) were used to analyze data. Cu, Zn, Cd, Mn, Ni,Cr and Fe varied as follows: 1.97-5.60(3.07) mg/L in water columns and 9.9-527.35 ppm in sediments,1.58 – 6.99(3.03 )mg/L in water columns and 37.69 – 875.64 ppm, 0.18–0.93 (0.62)mg/L and 0.37–11.46 ppm, 4.48–11.28 (8.51) mg/L and 184.95–547.45ppm, 9.83-20.50 (14.54.........

Abstract: Recently, the deterioration of water quality in the coastal areas of Akwa Ibom State, Southeastern, Nigeria due to saltwater infiltration into the freshwater aquifer has become a major concern. In this study, the geophysical method we adopted was the 2-D Electrical Resistivity Tomography (ERT) using resistivity meter and other accessories to obtain the field data. Wenner electrode configuration with electrode spacing ranging from 5 to 200m was used for field measurement and a total of twenty (20) randomly distributed ERT profiles were covered. The modeled field data revealed the resistivities and depth to bottom layer distribution across the study area with predominant lithologies being coastal plain sands.........

Abstract: The geology of Liji area is composed of members of the Pan-African granitoids (granite and pegmatite) and the Cretaceous sedimentary rocks of Bima, Yolde, Pindiga and Gombe sandstone Formations. Epigenetic fracture and porespace filling baryte mineralization of short dimension (7-45m long and 1-3.5m wide) occur within granite, pegmatite and sandstone of the Bima Formation. Binary plots of the major oxides of silica, alumina, total iron, potash and soda indicated that, the rocks are discriminated into distal, proximal and baryte separates. The distal samples show linear trend which is considered as the main trend and exhibited normal mixed pattern of the samples before the advent of hydrothermal fluid with no discrimination of lithologies. The baryte separates occupy the same region in all the plots reflecting that the two barytes are of the same origin..

Abstract: Water pollution now a days has become a serious concern for environment, mostly due to the presence of unprocessed effluents, chemicals and pesticides in it. Water is a natural resource, which is essential for living beings. Water is used in many purposes from drinking to industrial and agricultural areas. Due to water pollution, water quality is deteriorating day by day. Therefore, polluted water is a threat to human life as well as animals and plants. Water pollution affects not only the aquatic life but also is a threat to all-biological communities. Toxic level in polluted water provokes a number of diseases. Pollution free water is the only hope for the healthy life. The present article approaches a comprehensive study on different ways of water pollution and its impact on environment and human health..
