GEOCHEMICAL CHARACTERISTICS WITH RESPECT TO GOLD MINERALIZATION OF BENI/KAFIN-KORO AREA (PART OF SHEET 165, BISHINI SW), NORTH-CENTRAL, NIGERIA

A total of 21 samples were analyzed in the laboratory, Inductively Coupled Plasma-Atomic Emission Spectrum (ICP-AES) was employed in the whole rock analysis for oxides, total sulphide (TOS), total carbon (TOC) and loss on ignition (LOI), while Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) was employed in the analysis for trace metals including gold, and rare earth elements (REE) that were either associated with or served as pathfinder for gold. Statistical anal...

Radon soil–gas as a geological mapping tool: case study from basement complex of Nigeria

Abstract In an effort to quantify thegeogenic radon soil–gas potentialand appraise the use of radon tech-nique as a geological mapping toolin a crystalline basement rock terrain of Ile–Ife Nigeria, radon measure-ment concentration were made usinga radon detector instrument (EDARD-200) that measures radon isotopes by a scintillator cell coupled to a photo multiplier tube. The data were collected from soils derived from three different lithologic rock units. The observed values were then...

FORAMINIFERA BIOZONATION OF "WELL K-27", GREATER UGHELLI DEPOBELT, NIGER DELTA BASIN, SOUTH EASTERN NIGERIA

ABSTRACT Ditch cutting samples collected from interval 2590 3300 metres in Well K-27, Greater Ughelli depobelt, Niger Delta were studied for their lithology and foraminiferal content with the aim of dating and subdivision of the sequences penetrated by the well into biozones. The samples were processed using standard foraminiferal processing methods involving sample disaggregation and washing through a 63 micron mesh sieve, drying and picking and subsequent analysis of the foraminifera and ac...

FIELD REPORT ON THE GEOLOGICAL MAPPING OF IGARRA AREA

Basically, geological mapping involves the study of rocks; in situ, that is, in their natural environment and the representation of such rocks on a geological map. Furthermore, rocks of the Igarra area constitute part of the Basement Complex of southwestern Nigeria. On the basis of field relationships and petrological studies, these rocks can be grouped into gneissic rocks, meta-sedimentary assemblages, intrusive igneous rock bodies and sedimentary rocks (formations).   &...

EVALUATION OF LIMESTONE TEXTURAL AND GEOCHEMICAL COMPOSITION IN ONIGBEDU, OGUN STATE, IN RELATION TO ITS INDUSTRIAL USAGE AND DEPOSITIONAL ENVIRONMENT

Field relationship, petrographical studies and geochemical analysis were combined in investigating the depositional environment and industrial viability of limestone beds in Purechem’s quarry at Onigbedu. Field observation indicates a homogenous lithology of the beds with variation in textural and clastic composition. Petrographic study revealed that the limestone falls under the Biospamicrite and Wackestone classification based on the works of Folks, (1959) and Dunham, (1962) respecti...

SEISMIC CHRONOSTRATIGRAPHY: PROSPECTS IN PETROLEUM EXPLORATION

Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional eve...
