Gabbro from different localities was collected and characteristic using XRD and XRF. The results from XRD analysis of samples of gabbro from Wadies Nesreen, Saal, El Akdar and Ferian revealed the abundance of amphibole (hornblende Ca (Mg, Fe, Al) (Al, Si)8O22(OH)2, actinolite {Ca2} {Mg4.5-2.5Fe0.5-2.5} (Si8O22) (OH)) and calcic-plagioclase (labrador-bytownite) as the main components. Quartz, clinochlor and mica are recognized in addition to olivine and pyroxene.</p><p class="abstract">XRF data revealed the abundance of a number of macro- micronutrients that are essential for plant growth (notably calcium, magnesium, and trace elements: iron, manganese, zinc, and copper) and relatively low amounts of phosphorus and potassium.  The average of the sum of the 4 basic cations (Ca, Mg, K, and Na in cmol/kg of crushed gabbro) provided a sound basis for determining the effective cation exchange capacity (ECEC) of the fraction. The cultivation of sesame in the saline sandy clay loam soil without gabbroic rock was failed. This failure attributed to the sensitivity of sesame to salinity. The height of sesame plants cultivated with ground gabbro excited 5 feet tall which revealed high fertility and high moisture content. This fertility could be attributed to the ground gabbroic rock as soil conditioner.</p> ER -
