英文摘要	Tourmaline occurrences are found in the Eastern Desert of Egypt, particularly at the Wadi El-Gemal area, which is the locality of famous beryl mines dated back to the Roman times including the so-called Cleopatra's Emerald Mines. The collected tourmaline occurs in beryl-rich pegmatites and quartz veins. Infrared data of tourmaline indicate that dravite from three localities (Wadi Sikait, Wadi Um Sleimat and Wadi Um Addebbaa) can be distinguished based on the nature of the OH group and its vibrational bands. Also, reflectance spectra of fresh and altered dravite are distinguishable. Mineral inclusions (mostly hafnon zircon and REE-bearing apatite and monazite) in dravite affects the FTIR (Fourier transform infrared) spectra. Such spectra show influence of cationic substitutions in dravite, particularly M(2+)at the X-site and M3+ at the Y-site. Spectrometric measurements suggest that radioelements in tourmaline are not considerably high, whereas high radioactivity is restricted to the pegmatite bodies away from the metasomatic front with the serpentinite country rocks.
