Eutrophication Status of Shallow Wells in a Cretaceous Regolith Aquifer, Enugu Metropolis, South-Eastern Nigeria

The protection of groundwater quality is a critical aspect of ecosystem preservation. Nutrient (NO3-N and PO4-P) and non-nutrient (temperature and pH) assessments were carried out to study the shallow groundwater quality of Enugu metropolis in Southeastern, Nigeria. The result reveals that NO3-N and PO4-P are the main factors that endanger shallow groundwater quality safety of the Enugu metropolis. Total nitrogen (TN) and total phosphorus (TP) concentrations were observed to vary across the e...

Groundwater is one of the most valuable natural resources,playing a fundamental role in human health and wellness, socioeconomic development, and ecosystem functioning. Being the elixir of life,water resources ensure the stability of the ecosystem and the status ofhuman health. Hydrogeochemical characteristics of thegroundwater/surface water in the Ozalla were investigated by analyzingseven groundwater/surface samples, using various statistical methodsand graphical approaches to identify fact...

Comparison of The Petrology and Mineral Chemistry of the Coromandel and Kiwitahi Volcanic Rocks, North Island, New Zealand

ABSTRACT This is thesis was done based on the textural, mineralogical and mineral chemistry studies of arc rocks from the North Island of New Zealand. The rocks in the area are of two main groups: the Kiwitahi and Coromandel groups. Both the Coromandel group and Kiwitahi andesites are typically porphyritic with a phenocryst assemblage (20–60%) consisting of plagioclase + pyroxene + Fe –Ti-oxide in a granular groundmass rich in plagioclase laths and pyroxene microcrystals. The Kiwitahi sa...

Integration Of Ground Magnetic And Frequency Domain Electromagnetic Data, A Case Study From Nkwanta And Asuogya In The Western Region

ABSTRACT Ground magnetics and electromagnetic datasets were processed to interpret the subsurface geology and structure of the southwest of Ghana within the Tarkwain and Volcanics in the central part of the Ashanti belt. The study was aimed at mapping lithology, delineating structural lineaments and their trends as well as the trend of mineralization in the study areas. The data processing steps involved enhancement filters such as reduction to the pole, analytical signal, the first horizonta...

Tectonic Impact On Regional Structural Trends in Ultra Deep Water Cape Three Points

ABSTRACT A 3D seismic data merged with a regional 2D seismic data and well data acquired from Ghana National Petroleum Corporation were used to determine the tectonic impact on regional structural trend in the Ultra-Deep Water Cape Three Points. The Cape Three Point basin was fashioned from transform tectonic and has been severely influenced by the largest tectonic feature in the central Atlantic Ocean, the west-southwest – east-northeast (WSW-ENE) romanche fracture zone. The study area lie...

DETERMINATION OF AQUIFER PARAMETERS IN THE ISHIAGU EBONYI STATE USING GEOELECTRIC METHOD

ABSTRACTAn investigation was carried out on the groundwater potentials and aquifer protective capacity of Ishiagu area, southeastern Nigeria. The study area lies within the lower Benue trough of Nigeria and is underlain by the Albian Asu River Group and the Turonian Ezeaku Shales.The methodologies employed in the study include measurements of static water levels of 15 hand dug wells, pumping tests carried out on 4 boreholes and vertical electrical sounding (VES) of 20 stations. Groundwater po...

Groundwater Potential Of Akpugo In Nkanu Area Enugu, Southeastern Nigeria

Abstract: Groundwater potential at Akpugo and environs in Nkanu West Local Government Area of Enugu State has been undertaken in order to determine the groundwater status in the area. It lies on latitudes 060 2010011N to 0602510011N and longitudes 0070 3410011 to 00703910011E with an areal extent of about 86.49km2, over three geological units. A total of Twenty-five (25) vertical electrical sounding (VES) were acquired to determine the groundwater potential of the study area. Contour v...

GRANOMETRIC AND MORPHOMETRY ANALYSIS OF SANDSTONE DEPOSITED WITHIN AWKUNANAW AND ENVIRONS IN ENUGU AREA SOUTHEASTERN, NIGERIA

ABSTRACT: An intensive field mapping covering a total of nineteen locations was carried on. This study aimed at determining the geology and depositional environments of sandstone deposited within Awkunanaw and environs in Enugu area. Based on litho-facies the study area is underlain by five lithological units. Integrated granometric (textural analysis) was carried out on eight (8) friable sandstone samples collected from two locations based on their stratigraphic positions. An applicatio...

PALEONTOLOGICAL EVALUATION OF IMO SHALE AT UMUNAUMUAWO, EZEAGU, ANAMBRA BASIN, NIGERIA: AGE AND PALEOENVIRONMENTAL SIGNIFICANCE

AbstractThe lithofacies and foraminiferal assemblages of the Imo Formation exposed at Umuna-Umuawo, Ezeagu, Anambra Basin were evaluated for the purpose of environmental interpretation and age dating. Lithofacies were described based on lithology. The lithologic units of the succession are basically dark-grey to bluish-grey shales with presence of gastropod mineralized shells depicting a marine depositional environment. The shale is interbedded with patches of siltstone and clay beds. The met...

Heavy Metals Distribution in Soil and Plants in the Vicinity of a Municipal Dumpsite Along NPA Expressway, Warri

ABSTRACT This Research examines the heavy metal distribution of a dumpsite in Uvwie Local Government Area along Warri Port Express-Way of Delta State Nigeria. A total of eight (8) soil samples and (2)-plant sample were collected from the study area and also control site using a systematic sampling technique. Samples were taken to the lab and analyzed to determine the physicochemical parameters and heavy metal content. The dumpsite is contaminated with...

Investigation Of Geo-Environmental Hazards And Reclamation Of Abandoned Borrow Pits, South - Eastern, Nigeria

ABSTRACT Geo-environmental hazards associated with active and abandoned borrow pits are on the increase following rising trend in road construction. This situation presents a major challenge to Citizens, Environmentalists and Governments. Several highway failures have been directly linked to the action of erosion initiated by active or abandoned borrow pits situated close to roads. This study investigated environmental hazards and reclamation requirements associated with abandoned borro...

3d Seismic Interpretation And Reservoir Characterization Of “Diba Field’’, Niger Delta, Nigeria

ABSTRACT Interpretation of structures and reservoir characterization using 3D seismic cube and well data pose great challenges in mapping because of their complexities especially in structural deformations, and where identification of reservoir facies is a major challenge to plan delineation, field appraisal and development drilling. Thus, the project work takes a model approach. The ―DIBA‖ Field in the Niger Delta contains hydrocarbons that are largely trapped in sandstones and unc...

Diagenetic And Provenance Studies Of Sandstones In Parts Of Anambra And Afikpo Basins Southeastern Nigeria

ABSTRACTThe study of the textural and structural properties of sandstone sediments outcropping in parts of the Anambra and Afikpo Basins formed a basis for evaluating the diagenetic properties and source areas of the Cretaceous formations (Ajali, Afikpo and Amaesiri Sandstones, Mamu and Nkporo Formations) in the area. Preliminary field studies showed that the studied sandstone sediments were friable to moderately consolidated. Detailed petrological studies in thin sections...

The Origin And Hydrochemical Evolution Of Groundwater In The Lake Bosumtwi Area, Ghana

ABSTRACT Lake Bosumtwi is an important natural inland freshwater meteorite crater lake due to its scientific and socio-economic importance to both local and international communities. Although groundwater has been the main source of water supply for people living around the lake and visitors/tourists, very little work has been conducted with regard to the quality of the groundwater delivered by the aquifers within the lake basin. These aquifers are made up of the metasediments of the Bi...
