Radiometry Analysis of Alluvial Deposits Samples Collected from Sharm El-Sheikh
Area, Southern Sinai. Egypt
At Sharm El-Sheikh area, alluvial deposits derived from younger granites which exhibit association of important minerals (alkali feldspar, plagioclase feldspar, quartz, allanite, zircon, monazite chevkinite and magnetite) were subjected to radiometry measurements using HP-Ge detector. Activity concentrations of the radionuclides were found to be near to each other except K which measure high values. Element content of thorium and uranium (eTh & eU) was calculated to estimate uranium migration (in / out) process for the studied locality. Most of the studied samples were found belong to forbidden zone except samples Yg9 & Yg10. The results indicated migration of uranium in percent ranges from 7.31% to 32.51% for the locality of the collected and studied samples. Detrital Th was calculated to determine the corrected Thd and applied to Th/U dating which found to range between, 27 to 28 Ky. Migration time was also calculated using uranium original values.
