Summary: Aguilarite, Ag₄SeS, occurs in a hydrothermal vein deposit associated with sphalerite, chalcopyrite, galena, and native silver. Physical and chemical data agree with descriptions from Guanajuato (type locality). Differential thermal analysis of synthetic material indicates an inversion temperature of 122±1 °C. The mineral crystallized late in the paragenetic sequence, probably slightly above 200 °C.
