Assessment of radiogenic heat generation in a flood plain of crystalline Basement rocks
2019
Concentrations of radioelements in a flood plain of Crystalline Basement Complex are
determined, with the aim of assessing the radiogenic heat produced in the study area. Ten soil samples are
collected for analysis using Inductively Coupled Plasma Mass Spectrometry technique from ACME
Laboratories. The radiogenic heat contributions by each radioelement in the flood plain varied from 95.70
to 393.37 ρw/kg; 71.68 to 642.56 ρw/kg; and 0.0088 to 0.0188 ρw/kg for uranium, thorium and potassium
respectively. However, the total radiogenic heat production varied from 167.39 to 1034.9 ρw/kg, with
thorium being the major contributor to the total heat generated in the study area. Nine locations in the
study area are characterized by Low Heat Potential (LHP), while the remaining one is characterized by
Moderate Heat Potential. On average, the study area could be classified as LHP, which is in agreement
with some of the studies in crystalline terrain of Nigeria.
