Sulphosalts in the system AgSbS2-AgAsS2 have been experimentally investigated using dry methods. The solid solutions which form between ?-miargyrite and smithite have different structures. The EPMA data for the solid solution series show that there is an inverse relation between Sb and As. The cell parameters of the solid solution between ?-miargyrite and smithite increase up to about 50% of...

The ABS2 sulphides (A=Cu, or Ag), B=As, Sb, Bi) are a naturally occurring group of minerals, typically found in polymetallic vein deposits. Behind chemically simple, the minerals have a complex structure and undergo several temperature/composition phase transitions. In this study, synchrotron radiation is used to collect Ag, As, Bi, Cu, Cd, Hg and Sb K-edge EXAFS data from a series of synthetic...
