Abstract
Small lensoidal bodies of massive and disseminated chromitites have been examined inassociation with ultramafic rocks of the Mawat Ophiolite Complex (MOC), Iraqi ZagrosThrust Zone, Northeastern Iraq. The Chromites ore have variable thickness enveloped bydunite and of, exhibiting transitional boundaries to harzburgitic host rocks.The primary Chromite composition exhibits high Cr varieties; the average Cr# ofChromite is 0.714, with < 0.3 % TiO2 content, which may reflect the crystallization ofChromite from boninitic magma. The result of the gravity survey leads to lateraldelineation of the ore body and estimates an area of about 2800 m2. The thicknesses of different Chromite pods were estimated to be in the range of 10 – 35 m. Structural feature show that such ore bodies have internal structure making angle of 10–12 degrees with dunite wall and surrounding peridotite which indicates that Chromite ore subconcordant type.
