Analysis of Rocks and Minerals Deposits from Khewra

摘要

The mineralogy and geochemistry of the Baghanwala formation and Khewra sandstone exposed in Khewra Gorge have been investigated in detail. Emission spectroscopy was performed prior to the use of any other instrumental techniques in order to determine various metals element present in the sample. The geochemistry of the samples was carried out using X-ray spectrometric and atomic absorption techniques. The mineral assemblage of Baghanwala formation and Khewra sandstone comprises quartz, feldspars, dolomite, calcite, chlorite, glauconite, muscovite and degraded muscovite (illite). The geochemical investigations carried out for major element analyses indicated the abundance of SiO2 with subordinate quantities of CaO, MgO, Al2O3 and Na2O. The correlations of the major elements with each other verify their presence in their respective minerals. The geochemical and mineral analyses indicate the arid, hot and Lagoonal palaeo-environment.
