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

bstract -The petrographic and geochemical study of sandstones of Eze-Aku Formation (Turonian) outcropping in Ugep area southern 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 showcoarsening upward sequence, slightly bioturbated, cross-stratified, rippled bedded which infer foreshore to shallow...

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...
