Furthermore, geology is employed as a tool in identifying the causative element(s)/mineral(s) of the epidemic. This is achieved through desk study and field work aimed at identifying the host rock or soil and to map its lateral extent. Water sources such as lakes, rivers, streams and man- made wells are not left out in such studies. Mines, quarries and ore processing sites are all brought under the surveillance of geologists. This is achieved through a comprehensive mix of three aspects of geology: geochemistry, mineralogy and hydrogeology. | Furthermore, geology is employed as a tool in identifying the causative element(s)/mineral(s) of the epidemic.
