Qasr Al-Hallabat (QH) basaltic rocks were investigated aiming to understand their, mineralogy, petrography and geochemistry features, and to achieve that a total of eighteen representative rock samples were selected for both geochemical and petrographic analysis from several sites in the study area. Petrographic characteristics were analyzed by optical microscopy after preparation thin sections, for eighteen rock samples, which show that all basalt samples have minerals comprising: olivine, clinopyroxene (augite), plagioclase (labradorite), opaques and some secondary minerals such as (Iddingsite). Normative mineralogy by using CIPW norm showed that (QH) basalt samples dominated by olivine, augite , hematite, apatite, sphene, and nephline. and (QH) basalt can be normatively classified as alkali olivine basalt. Some textures that may be evident on microscopic examination such as porphyritic, vesicular, glomeroporphyritic, intergranular, embayment, seriate, trachytic , zoning olivine and ophitic to sub - ophitic texture. X - ray Floursence (XRF) was used for whole rock major elements (SiO2, TiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O and P2O5 in wt%) and trace elements (Cr, Sr, Zr, Ni, Ba in ppm). Geochemical analyse reveal that the basalt are alkaline and includes into sodic series. The normalized trace element diagrams suggest that (QH) product of the asthenospheric part of the mantle at >100km depth. The geochemical variation trends of (QH) basaltic samples supposing that the composition of these magma have been influenced by fractional crystallization without clear evidence for crustal contamination. |
