Hawleyite is a rare sulfide mineral in the sphalerite group, dimorphous and easily confused with greenockite. Chemically, it is a cadmium sulfide, and occurs as a bright yellow coating on sphalerite or siderite in vugs, deposited by meteoric waters. It was discovered in 1955 and named in honour of mineralogist James Edwin Hawley, a professor at Queen's University in Ontario, Canada.
