英文摘要	The Abu Rusheid area, part of the Arabian-Nubian Shield, lies about 90 km southwest of Marsa Alam City. The cataclastic rocks in this area include protomylonites, mylonites, ultramylonites, and silicified ultramylonites. Mylonite rocks make up about 65.0% by volume of the cataclastic rocks, and many of them have high concentrations of visible orange-colored thorium and yellow-colored uranium minerals. XRD and SEM analyses revealed the presence of thorite, kasolite, monazite, zircon, xenotime, hematite, and ilmenite. The mylonite rock studied here contained high concentrations of thorium: > 1% in some cases, and an average of 3962 ppm. A sample assaying 10,000 mg/L was leached at 50 degrees C for 1.5 h by 6 M HCl using a S/L ratio of 1/6, which dissolved about 95% of the thorium. The thorium was precipitated from the leach liquor by oxalic acid. Highly pure thorium oxide was then prepared and identified via qualitative (SEM/EDX) and quantitative (ICP-OES) analyses.
