Identical to dimethylbenzphenanthrene (Handbook of Mineralogy) but possibly a complex mixture of polycyclic aromatic hydrocarbons (PAH). Raman spectroscopy studies indicate that it may be a mixture of complex hydrocarbons including benzonaphthothiophenes (chemical formula: C16H10S) and dinaphthothiophenes (chemical formula: C20H12S) Approximate abundance of PAHs contained in idrialite from Skaggs Springs (Wise et al. 1986) : picene [40%], chrysene [7%], benzo-phenanthro-thiophene [10%], dibenzo-carbazole [trace], dibenzo-fluorene [33%], indeno-fluorene [7%], and benzo-indeno-fluorene [4%]. Potentially dangerous substance: the PAH contened in Idrialite are toxic.
Most Common Activator: Intrinsic organic material
