Marrite (mar’-ite) is depicted by the chemical formula PbAgAsS3. It is the arsenic equivalent of mineral freieslebenite (PbAgSbS3) but also displays close polyhedral characteristics with sicherite and diaphorite. Marrite was named in honor of geologist John Edward Marr (1857–1933) of Cambridge England.
