Hawleyite (original) (raw)
Specific Gravity:
4.87 (Calculated)
Name:
Named in 1955 by Robert James Traill and Robert William Boyle in honor of Professor James Edwin (Ed) Hawley [September 27, 1897 Kingston, Ontario, Canada – April 20, 1965], professor of mineralogy at Queens University, Kingston, Ontario, Canada and a specialist in sulfide ore deposit theory.
Yellow powdery coatings that also look like greenockite. Much that is attributed to greenockite is actually hawleyite.
Approved, 'Grandfathered' (first described prior to 1959)
