   <mods:abstract>Methodological aspects and results from the compositional-structural relationships of
su/phosalts are summarized. These sulphosalts correspond to 5-Bi-Ag and 5-5b-Ag systems
presenting pseudoisometric characteristics.
Attending to the paragenetic and crystallogenetic trends, they seem to be the result of
an epithermal late metallogenic episode. Thermal sequences into these systems have not
been detected.
