Processing and characterization of chalcopyrite (CuFeS2) sample from Botswana

Abstract: Beneficiation of chalcopyrite and most minerals in general requires specific conditions and raw materials based on characteristics of the mineral to optimize processing hence income. Therefore characterization of minerals is an important aspect in mineral processing. In this investigation X-ray diffraction (XRD) and Scanning Electronic Microscope (SEM) techniques where applied on a sample of chalcopyrite. XRD was mainly applied to obtain phase compositions, lattice parameters hence...

Testing the spectral resolutions of the new multispectral sensors for detecting Phaeosphaeria leaf spot (PLS) infestations in maize crop

Abstract: Maize is one of the most important subsistence and commercial crops in the world. In Africa, it is regarded as one of the most popular food crops. Recently however, significant losses due to Phaeosphaeria leaf spot (PLS) infestation have been reported. Therefore, techniques for early detection of PLS infestation are valuable for mitigating maize yield losses. Recently, remotely sensed datasets have become valuable in crop assessment. In this study, we sought to detect early PLS inf...

Structural and Petrological Evolution of the Shai Hills Tectonic Suture Zone, Southeastern Ghana.

ABSTRACT High Pressure (HP) mafic granulites (mafic garnet gneisses) in the Shai Hills suture zone occur as NE/SW trending isolated inselbergs in the Accra plains. They characterize the suture zone rocks of the Pan-African orogeny in Ghana. Various aspects of the Shai Hills suture rocks have been studied yet relatively little is known about its structural and deformational evolution. This work presents a new research into the structural, petrological and deformational evolution highlighting ...

INTEGRATION OF ELECTRICAL RESISTIVITY AND INDUCED POLARIZATION FOR SUBSURFACE IMAGING AROUND IHE POND, NSUKKA, ANAMBRA BASIN

ABSTRACT Integration of 2D geophysical methods, Electrical Resistivity Imaging (ERI) and Induced Polarization (IP) were used to study the subsurface geology and structures around Ihe pond, Nsukka in Anambra basin. The research work has delineated the geologic structures and strata responsible for the water in the pond, and determined the origin of the Pond. Three 2D resisitivity profiles of maximum spread lengths of 500, 400 and 500m were run around the pond. Horizontal profiling, using Wenne...

PALEO-ENVIROMENTAL ANALYSIS OF ANAMBRA BASIN SEDIMENTS. A CASE OF ACHARA-UGWUEME AND ENVIRONS, SOUTH EASTERN, NIGERIA.

Abstract:  Paleo-environmental study of Achara-Ugwueme in Anambra Basin was studied using Textural analysis parameters, which includes paleocurrent analysis, sieve analysis and pebble morphological methods. The paleocurrent result shows that the variance value is 1701 which indicates that the units were deposited in fluvial environment. The azimuth with rose diagram suggested southwesterly direction of paleocurrent during the time of deposition, thus pacing the provenance at northeast, p...

Effects Of Eucalyptus Plantation On Soil Physico-Chemical Properties In Thiririka Sub-Catchment, Kiambu County, Kenya

ABSTRACT Trees are very important in Thiririka sub-catchment of Kiambu County in Kenya for reasons such as income generation, soil and water conservation, biodiversity conservation, charcoal production, erosion control, among many others. Eucalyptus spp. (E. grandis, E. saligna and E. globulus) remain part of the dominant tree species planted in the Thiririka sub-catchment. Although these species are planted in various spatial patterns in the sub-catchment to meet the demand for fuel wood, ...

Geological Distribution Of Mineral Resources In Southwestern Nigeria

  ABSTRACT The occurrence and distribution of the resources of southwestern Nigeria are intimately associated with the geology of the area. The basement complex of southwestern Nigeria lies to the east of the West African Craton, an area that has undergone late Precambrian to early Palaeozoic orogenesis. To the east and south, the Mesozoic-Recent sediments of the Dahomey and Niger Coastal Basıns cover the Basement Complex, The mineral resources of southwestern Nigeria are grouped into thre...

Expected impacts of active mining on the distribution of heavy metals in soils around Iludun-Oro and its environs, Southwestern Nigeria

This present study is aimed at evaluating the level of environmental degradation and potential ecological risk in soils around an active (tantalum-niobium) mining site of Iludun-Oro, southwestern Nigeria. A total of 18 topsoil samples were randomly collected from different parts of the study area and analysed using the inductively coupled plasma-mass spectrophotometry. The concentrations of Pb, Zn, Fe, Cu, Cr and Ni varied between 0–678, 7–222, 1.64–8.87, 8.8–145, 1.4–81 and 1.6–9...

The use of Grimmen clay (TS-136) as a substitute for Geopolymer cement component``(Green Concrete)

Abstract The term Geopolymer was introduced to represent the mineral polymers resulting from geochemistry. The process involves a chemical reaction under highly alkaline conditions on Si-Al minerals, yielding polymeric Si-O-Al-O bonds in amorphous form. The actual compressive strength of the concrete depends on various parameters such as the ratio of the activator solution to fly ash, molarity of the alkaline solution, ratio of the activator chemicals, curing temperature etc. In recent years,...

Provenance and Tectonic Setting of Amasiri Sandstone (Turonian) in Ugep Area, Southern Benue Trough, Nigeria: Evidences from Petrography and Geochemistry

bstract - The p et rographic and geochemical study of sandstones of Eze - Aku Formation (Turonian) outcropping in Ugep area souther n Benue Trough Nigeria was carried out to ascertain the sandstone provenance and tectonic setting. Field studies show that the sandones occur in linear, parallel northeast - southwest trending ridges alternating with shale sequence. The sandstone facies show coarsening upward sequence, slightly bioturbated, cross - stratified, rippled bedded which infer fores...
