Abstract
Ei-Rosis area is mainly covered by syeno- and alkali feldspar granites intruded into the granodiorites with sharp contacts. The alkali feldspar granite is dissected by WNW-ESE shear zone along which alteration products such as hematitization and kaolinitization are observed. The detailed radiometric survey along the shear zone revealed the presence of numerous radiometric anomalies. The X-ray diffraction (XRD) and Environmental Scanning Electron Microscope (ESEM) studied on the anomalous samples revealed the presence of cliffordite mineral (Ute309) and U-bearing zircon.
The distribution of uranium, thorium and potassium along the shear zone is also studied in detail and a radiometric contour map of each element is constructed to illustrate its distribution. The obtained contour maps show that the distribution of these elements is largely controlled by the fracture system developed along the shear zone and the presence of the alteration products containing iron and copper mineralizations. The alteration products and the minerals identified may suggest hydrothermal activity in the shear zone.
