Formula:
Pb0.8Tl0.1Sb1.3As0.8S4
Simplified Pb(Sb,As)2S4.
Colour:
Black
Lustre:
Metallic
Hardness:
Crystal System:

Member of:
Name:
Named by John L. Jambor in 1967 in honor of Robert Mitchell Thompson (28 July 1918, Moose Jaw, Saskatchewan, Canada - 15 April 1967), professor of mineralogy, University of British Columbia, Vancouver, Canada. He had a special interest in ore minerals and deposits. Thompson means "son of Thomas"; the latter is Aramaic for "a twin". The name is doubly appropriate in alluding to the polysynthetic twinning present in the mineral.
