ABSTRACT: Evaluation of Marwit Rod El Leqah deposit as
pegmatite high purity quartz source for advanced applications was conducted
through the geological, mineralogical and geochemical studies. Elemental
analysis of a representative quartz sample showed that the quartz deposits were
classified as medium purity quartz with 99.575% average SiO2 content
and about 0.422% (4220 ppm) of accompanied mineral. Field study and petrography
investigation using optical polarized transmitted microscope and reflected
light microscope revealed that these impurities were mainly found as solid
particulates of iron oxide, muscovite, rutile, orthoclase, granitic rafts, and
as fluid inclusions as well. Moreover, structural undesirable trace elements
were also presented in the quartz sample.
