/ˈpɪrˌsaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Pearce , -ite suffix¹.

Etymology: < the name of Richard Pearce (1837–1927), British-born metallurgist and chemist + -ite suffix¹ (see quot. 1896).

Mineralogy.

A black, lustrous, brittle mineral consisting of a sulphide of silver and arsenic, Ag₁₆As₈S₁₁, occurring as tabular crystals of the monoclinic system and usually containing copper in place of some of the silver.

1896 S. L. Penfield in Amer. Jrnl. Sci. 152 18 The author proposes that hereafter the name polybasite shall be restricted to the antimony compound..and to make of the corresponding arsenic compound..a distinct species. For the arsenical mineral he takes pleasure in proposing the name pearceite as a compliment to his friend, Dr. Richard Pearce, of Denver.

1942 Econ. Geol. 37 491 Pearceite, recognizable only in polished section, is almost invariably associated with pyrargyrite.

1963 Amer. Mineralogist 48 567 The traditional polybasite and pearceite actually are members of two separate solid solution series in which Sb and As substitute mutually.

1995 Geochim. et Cosmochim. Acta 59 3573/2 We report reversal brackets on As-Sb partitioning between polybasite-pearceite and pyrargyrite-proustite.
