MINERALOGICAL and physical characteristics of natural chromites from Oman ophiolites have been recently investigated using M6ssbauer spectrocopy (MS), X-ray diffraction (XRD) and Scanning electron microscopy (SEM) by Al-Alawi et al. (1996). From the MS analysis together with the SEM data, they derived the chemical formula for specimens collected from two separate chromite deposits named Tawiyah...
“Laoshan Jade” is located in the Yangkou area of Sulu UHP metamorphic belt. This first time a systematic research study performed on its conventional gemological characteristics, mineral compositions, geochemical and petrogenesis using polarized light microscope, an electron probe microanalyzer (EMPA), X-ray fluorescence spectrometer (XRF), Raman spectrometer. The characteristics are consistent...

The most important geological units in East of Sarbisheh are Upper Cretaceous ophiolites assemblages that are predominantly serpentinized ultramafic in composition (dunite, harzburgite and pyroxenite). Chromite deposits in these rocks have generally various forms such as lenticular, layered and disseminated with varying dimensions. Textural studies on Golab Chromites show that they have primar...
