Idrialite or idrialine is a soft orthorhombic hydrocarbon mineral with chemical formula: C22H14. It is usually greenish yellow to light brown in colour with bluish fluorescence.Raman spectroscopy studies indicate that it may be a mixture of complex hydrocarbons including benzonaphthothiophenes (chemical formula: C16H10S) and dinaphthothiophenes (chemical formula: C20H12S).
