    The geochemical composition obtained by Xray fluorescence shows that the material of the study area are richer in SiO 2, Al 2 O 3 and Fe 2 O 3. The SiO 2 /Al 2 O 3 of all the samples were greater than 1 indicative of kaolinitic clays while Fe 2 O 3 /Al 2 O 3 are less than 1 indicative of the presence of iron based compounds.

  • Effects of phosphatization on the geochemical and

    Geochemical and mineralogical investigations of nonphosphatized and phosphatized crust layers revealed significant differences that are not simply dilution effects by CFA. Certain elements are depleted in old crusts compared to young crusts in the order Si > Fe > Al > Ti Co > Mn Pb others like Ni, Zn, Cu, Y, and REEs (rare earth elements) are mostly enriched.

  • Mineralogical and geochemical characteristics of coal ash

    The determination of the mineralogical composition was done for all of the groups the geochemical analysis was carried out only for group II. In accordance with the high SiO 2, Fe 2 O 3, CaO, and SO 3 content of the ash, quartz (SiO 2), hematite (Fe 2 O 3), and anhydrite (CaSO 4) are the major crystalline phases for all of the ash groups. The

  • Geochemical and Mineralogical Maps, with Interpretation

    Most often, the geochemical and mineralogical patterns reflect the composition of the underlying soil parent material with some modifications caused by leaching of the more mobile elements (for example, calcium and sodium) in the humid areas of the country.

    A number of studies showed that hydrothermal fluids have significantly influenced the geochemical and mineralogical composition of Lopingian coals in southwestern China (e.g., [26,48,86,93,94,95]). The evidence for the No. 1 Coal and carbonaceous rock benches subjected to hydrothermal fluids includes: (1) Chamosite identified in samples SGT1F1

  • Effects of waste deposit geometry on the mineralogical and

    The geochemical distribution of chemical elements at the surface of the waste deposit has also been interpreted using the Principal Component Analysis. Firstly, this technique was performed for 17 geochemical variables , accounting for 72.49% of all data variations. The first principal component (F1) contains 45.37% of the total variance and

  • Mineralogical and Geochemical Characterization of Gold

    Epigenetic, NS, NNESSW quartz veins crosscut metapelites and metagabbro in Maru area. The objectives of this work were to study field, mineralogy, and geochemical characteristics of gold bearing quartz veins and soils. Euhedral and polygonal magnetite with hematite constituted the major ore minerals. Quartz occurred as main gangue phase with appreciable sericite and chlorite. The
